- 100ms timeout is now immediately aborted if ACK failure is detected, i.e., no response to Slave Address being sent. Master sees NACK on 9th SCL clock.
- NOTE: If Slave is disconnected, Master must still have pull up resistors on SDA and SCL to properly detect an ACK failure. Without these, the I2C interface will see many Bus Errors (BERR) and potentially ARLO failure.
- Improved comments for I2C Receive routine (HAL_I2C_Request_Data())
- Added missing re-enable commands for interrupts in SW RESET function
- mode and ackFailure elements added to end of STM32_I2C_Info structure to preserve organization in memory for DYNALIB, allows older I2C apps to work with new I2C library.

Regarding dynalib and the STM32_I2C_Info struct - that struct isn't passed out to other modules (the definition is in a C file so no sharing of the struct event). Thus it's only used internally within the I2C HAL meaning versioning isn't a concern here - feel free to place the new values where they make sense. |

Ah ok cool, probably a good habit to get into anyway as structs rarely need to be organized :) |

Once I know this is working well for everyone, I can make the same changes to the Core. |

Fixes the build for the Core and newhal. 77de71b test application for backup ram. 8257a60 save a 4 byte value in memory which is used to detect if the retained variables need initializing. The feature `FEATURE_WARM_START` is derived from this, since this appears to be the only reliable way to determine if the contents are still valid or not. (Without this, the backup regulator can still be active even when the device has been powered down for 45s, but the backup SRAM contents are not valid.) 5ca64ae PARTICLE_NO_RETAINED define to allow disabling of the `retained` keyword for libraries already using that name. 398e811 always enable the backup SRAM so that we can read/write data.

This is invoked by Particle.process() when called on the application thread, allowing the application to pump it's own messages. Addresses the issue raised in #659 where a never ending application loop will not be able to service cloud function calls. The `system_internal` function provides a pointer to the ActiveObjectBase instance for the application thread so that we can test that the queue is serviced. 55a5b21 WiFi.dnsServerIP() / WiFi.dhcpServerIP() a137615 logging when the cloud connection is terminated due to inactivity (system or application not pumping cloud events.) 8fc3f56 Merge pull request #656 from spark/feature/pulsein a316e92 Merge pull request #681 from spark/feature/serialevent 9b30238 Merge pull request #691 from spark/feature/system-version-api af77c9d pulseIn() for Photon/Core/Electron, with tests 275466b spark_process() needed for non-cloud builds too. 9205307 fix for issue #680.

Previously the symbols SPARK_WIRING_NO_I2C/SPI were used to exclude these globals, but since this applies to a shared library, the build would then break when compiling other modules (e.g. the application) that requires I2C or SPI (Typically undefined reference to Wire.) The fix is to separate out the globals into a new module so that only the modules that need the wiring globals get them by depending on the new wiring_globals project. 83bffcb polarity of queue take/put was inverted, causing a hard-fault. 88ac7f3 Merge branch 'develop' (0.4.5 release) into feature/non-blocking a422698 Serial.printf/printfln bba379f Merge branch 'release/v0.4.5' into develop 72b855b fix a typo in system_mode() due to similarly named variables.

Checking gihub history, this was never added. d763c50 primitive release scripts 15c6b60 Merge branch 'release/v0.4.5' into develop 0176385 disable LTO for the core since it introduces instability in the cloud (but not locally) e729350 setting the unix time calls mallic, which is not allowed in this early startup phase. fixes #601 5f8c1fa fixes solid green LED when wifi connection goes down in automatic mode, and ensures network watchdog is set before attempting to connect (On the photon connection is synchronous, so the watchdog is cleared via a callback. If it's intiialized at the end then the net watchdog is re-armed incorrectly.) c1f649a move the network watchdog to network_connect so failed wifi connections are retried after 30s always, even in semi automatic mode when the application calls WiFi.connect() 3b7a0de ensure like signed/�unsigned comparison. 4.9.3 compiler versions generate an error here.

Tested on Core and Photon. 85ed93e fix for signed/unsigned arithmetic in handling the microseconds part of the delay, which caused some very large delays to be incorrectly computed. dee1f9d fixes issue (private repo) 99 - Core restarts when wifi drops. This was due to attempting to close the cloud socket on notification from the CC3000 of the wifi disconnect, causing a deadlock. 750a024 Don't issue QoS commands if not a 3G module 31e3e46 Merge branch 'release/v0.4.5-rc.2' into develop dfa5642 Merge pull request #591 from spark/feature/hidden-ssid 8a8dedd bumped version prior to release f105795 updated bootloader to include the DFU mode fix. And removed the features flags since this could disable DFU. 4ff04ac move appending the separator to TARGET_PATH until after build.mk has been evaluated, since it may update TARGET_PATH.

Hooked spark_function, spark_variable to work on the system thread (since these are one-off operations.) 6af583e platform headers (concurrent_hal_impl.h) required by system so removing the conditional. 1f5ac9f Merge branch 'feature/electron' into develop-feature/electron-merge 3798358 Merge branch 'feature/electron' of https://github.com/spark/firmware into feature/electron a767a67 Fixed missing interrupt handler issues... e0c6824 merged feature/electron into develop 033b664 common main() entrypoint for bootloader and system firmware 4ebd579 holy fatfinger batman 888fbab Fix tone_hal build issue for photon 358fc50 Merge pull request #584 from spark/feature/i2c_multiple_interface_support cec9ade Updated template and core's i2c_hal (similar to photon's changes) d2b2307 Removed old i2c3_hal.h includes. PMIC & FuelGuage PASS using Wire3 c3971a6 Updated FuelGauge class methods using Wire3(I2C3 peripheral) instance 1fb4962 Updated PMIC class methods using Wire3(I2C3 peripheral) instance 56bee2a Updated TwoWire class methods, new instances Wire1 and Wire3 added 7263b9e Conditional Wiring_WireN defines added to electron platform 1fcce6f HAL_I2C_Init API added to hal_dynalib_i2c.h b243ca4 Important: I2C HAL re-engineered to support multiple interfaces ae58e06 Delete redundant i2c3_hal files since i2c_hal would be extended (WIP) 3c86f80 additional files for threading 742b38c extended system-part2 SRAM by 2K. Need to find out what causes this large jump in static SRAM usage. c20fce5 run setup/loop regardless of system state when system threading enabled. ba19617 System threading conditionally compilable so is a no-op on non-threaded platforms. 1757888 system threading working. 13934a9 wip - synchronous calls / marshalling 8a657ef rewrite os_thread_xxx() functions to use FreeRTOS directly so they are compatible with the Electron too. Replaced cpp:channel with a RTOS queue just to investigate if that was the cause of the SOS. Current state: Device completes handshake then SOS's. 637379b imported cpp::channel (Go Channels) as the backbone for the ActiveObject implementation. Implemented required APIs from gthread to support STL concurrency primitives required by cpp:channel. afa7db5 separated spark_cloud into spark_cloud_internal so we can clearly see what is user facing and what is not. 3f4520b SYSTEM_THREAD macro, implementation and tests 5e99386 dynalib modules can be implemented in C++ 3ac6fb1 SYSTEM_THREAD macro 0e23434 Generate I2C STOP after slave addr NACK, I2C SW reset all timeouts 7dbfc6e Wire.endTransmission() returns unique values ff76ffd Core i2c_hal correction : address << 1 required since it's removed from STM32F1 driver d10cdf9 I2C hal fix for Core (Similar to that was done for Photon) b9db392 Important: Improved I2C Master Byte Receive API method d7ff6a6 Added I2C error management code to monitor and clear error events e2adef6 Improved I2C hal code for STM32F2 series 95998a1 Added I2C_BUFFER_LENGTH in i2c_hal.h for partial arduino compatibility. Fixes #475. f381b65 Factor cloud implementation into API functions and internal functions. 45e1383 module_system_part2.c -> cpp so that we can include headers with namespaces in. 203a7cb All SPI interface speed defaults to 15Mbit/s 2f062f4 changelog ac88ec1 simple account for network latency when computing time. addresses #581 0986ce0 Added clock configuration tool's application note d923512 Merge branch 'develop' of https://github.com/spark/firmware into develop a3c15be Added Clock configuration tool for STM32F2xx microcontrollers 0f61f66 reworked static IP API - useStaticIP/useDynamicIP 82a81b4 update changelog 819cbc2 Merge pull request #568 from spark/feature/wifi-scan 1af94a4 WiFiAccessPoint::ssid_size -> ssidLength, and max_data_rate -> maxDataRate. 347ab9e erase result output struct so that unassigned data is 0. (wifi scan channel is not reported by the cc3000 so this is unassigned.) 64ad8cf WiFI.scan for the Core 5bff614 #567 - WiFi.scan function b0b0c56 Merge pull request #571 from spark/feature/tcp_peer 171182d TCPClient.rmoteIP update changellog e911fe0 #551 TCPClient.remoteIP() to retrieve the IP address of the peer. (Typically the client that connected to a server socket.) 8009968 fix debug log referencing size rather than buffer_size eb42fdf Merge pull request #578 from spark/feature/wait_for 6b83757 Merge pull request #572 from spark/feature/time_format e2e5a8d Merge pull request #575 from spark/feature/servo_trim 9566269 tweaked API names as agreed with the team 926b29c Merge pull request #556 from spark/feature/fast-pin-using-bit-band 97f6009 Updated Core's interrupts_hal using the newly added gpio_pin_source 1ec21c8 HAL_RTC_Configuration() conditional code correction b4817c1 Updated HAL_RTC_Configuration() - Fixes #480, #580 7e37113 start to factor out OTA module handling from photon to shared stm32 folder so it can be used on the Core. 00c129a optional flag to not set the LED in network_on. On the core, the LED briefly goes blue while connecting to wifi. 9f8cfd9 platform header included just to be sure 11473a0 fix for FIRM-194 - P1 USB descriptor updated, and changed company from Spark Devices to Particle IO to match the descriptor in the Windows driver. 50684c9 Signed USB driver for the P1 460e605 make travis-ci build matrix output more verbose to assist in diagnosing severity of build failure ec997f8 Merge branch 'feature/build-matrix-bugfix' into develop 235bf4d Disabling USE_BIT_BAND : Bitbanding is much slower! as per @pkourany 75f73c2 removed deprecation warning on Spark. This was mistakenly introduced in 0.4.4. Will be removed for 0.4.5 (when many Core users will upgrade) and re-instroduced in 0.4.6 when we will publicly deprecate Spark APIs in firmware, and remove the deprecated APIs in 0.5.0 4c98931 fix regression in bootloader. 9ea71cb Merge pull request #543 from munirent/feature/wiced_last_error bb4021b Add a method to retrieve the last error on a socket 98b851a remove warnings in api tests. missing header. (Is being included indirectly, but make it explicit.) 2553b34 waitFor proposed implementation. #415 d2bdad1 Regression test and fix for #577 - timeStr() not concatenatable. f6deabd #455 - configurable format to Time.timeStr(), and a generic time formatter `Time.format(time_t, format_spec)` based on `strftime()`. Complete with API and unit tests. 7c3d9cc fix for broken Build on the core - socket_join_multicast/socket_leave_multicast didn't declare parameters. This caused gcc to fail. c63329b fix and tests for #576 - sprintf floating point support was not compiled in due to a logic inversion in the makefile. 91faefc basic release build script. c071773 missing file - should have been in previous commit. 145a487 map network interface to WICED WLAN interface constants in sockets layer. 2889d30 remove unfinished merge delimiters from recent PR 71bfef4 Merge pull request #573 from stevie67/develop 1e260f7 fix for #249 - add Particle.h header. 66362cb fix for #120 - provide a setTrim() method that users can minutely adjust the servo timing. Untested. 0f49b51 allow cipher to be passed to WiFi.setCredentials, which is needed in the Photon to fully specify the credentials, and not require scanning the AP. #574 0929892 Fixed merge conflict. 451da05 Merge remote-tracking branch 'spark/develop' into develop d182e33 this was not working as a result of flags. Before sleep, network_off() is called, which doesn't set the deliberate disconnect flag. In taking down wifi, HAL_WLAN_notify_disconnected is called, which then sets up a network watchdog for 2 seconds. When the 5 second timeout causes wifi to wake up, the watchdog has tripped, and this causes the exceptional path through manage_network() (same as when wifi is reset.) The combination of flags meant manage_network() did nothing and never restarted wifi on the background loop. d46c972 Update changelog. Remove warnings in api tests. 0df1758 Ensure LED Signaling (Application Control) is turned off when the system needs to control the LED. Fixes #362, #472, and #544 c5d13b5 add BusFault and MemManage panics to the photon a2f651f factored WiFiCredentialsReader into a generic base class and a WiFi-specific subclass. 0315184 rename WiFiCredentialsReader class to SystemSetupConsole 9e268ef rename wifi_credentials_reader to system_setup 0952c42 Merge pull request #451 from spark/feature/static_ip c301783 Merge pull request #452 from spark/feature/udp-dynamic-buffer ea3fa03 static IP support 6f87408 remove deprecation warnings, and fix use of VERSION_STRING define which must now be stringified before use since it's passed from make. 75b764d UDP.setBuffer() for explicit buffer management. This seems more managable than overloading begin() with that. 41cca9d implementation of dynamically allocated UDP buffers 8e8f95b Add directions on where to find help building the develop branch. ab94de5 bump version string (but not version ID so we don't block automatic updates of the final release of 0.4.5) fdc6979 Added unit test, pass if to wiced calls, extended return value doc 4a7eb05 missing ` (sigh) 5c78cfe github markdown fix - anchors in lowercase. #564 a598c18 Recipes and Tips section in build docs d7b4146 Merge remote-tracking branch 'spark/develop' into develop 63be76f Merge pull request #534 from munirent/feature/event-handlers-in-objects 6492505 fix for #563 - the scaling operation was causing values greater than 4294.965149 to be incorrectly converted due to overflow. Using 64-bit precision fixes this. 75e42b2 clear the network config when the network is disconnected so that the background loop re-establishes the details on the next connection. Addresses #560. 8c2c417 fix for #588 - ensure the connect flag is cleared. 13469d8 signed electron USB driver 556ce50 Address review comments c06836d CortexM3 Bit-Band access to perform fast GPIO atomic read-modify-write 5971bf8 Added gpio_pin_source to PIN_MAP in Core's pinmap_hal 7a2106c Change Spark in comment to Core 2b65627 Renamed join/leave multicast to camel caps 3cde3a2 Added joining and leaving multicast groups b49030e set ANT_INTERNAL as the default, bump versions for release. 690322a return success from UDP.begin() 2978a3f fixes #552 - UDP.begin/write now return expected values. f6550ca Merge pull request #549 from pkourany/patch-2 d144e7a Added link to debug build docs e7aadf6 Update fast_pin.h c747f9c store version string in one place (build/version.mk) ec28f84 bumped version 86f59bb ANT_AUTO is the default since it prevents photons with only an external antenna from connecting. 4ab10b7 fixing a typo - debugging.md f89e23b Add pinReadFast(_pin) 2c8b5d0 Merge pull request #548 from spark/feature/otastress 466962f brief docs on how to use d41f66b removed default antenna selection ddf9e20 the address of spark_receive_last_bytes_received is always > 0. The intent is to always read if the previous read was successful. Yet removing the & causes the cloud to never connect, being stuck in a slow flashing cyan forever. 28db6fc don't send chunk missed messages when not in fast OTA mode since these can lead to duplicate chunks, and a corrupted mage (since chunks are not indexed.) 258dc26 OTA stress test 9acd451 added socket locks 2c98d1c FIRM-184 - XHR headers on all HTTP responses during SoftAP. Requires changes to WICED. bf33533 updated test application with newer test functions e1c98c4 regression: output filename when specifying APPDIR should match the last directory in APPDIR. a8295a6 fix for missing slash separator when specifying TARGET_DIR d09f8a2 rename bootloader main() to application_start() temporarily for electron 593dc21 Add new feature C++ handler #534 to changelog 54fcd90 Check handler_data in event_handler_exists ec614e3 Add C++ handlers and handler_data to subscribe f1d2773 Add tests for C++ handler Spark.function, Spark.subscribe, attachInterrupt 99349b8 changelog for #545 a3c4ed1 Fixes randomly inverted RX, TX PWM. Thanks @janne68! 6b0ffb1 remove rundunant socket count for http server and increase task stack size to avoid hard fault. HTTP SoftAP test passed. c735044 revert to minimum version of 4.8.4 for arm gcc. The libraries have a different suffix (_s for 4.8.4, _nano for 4.9.3) so the suffix is conditional on the version. 5e3ebbf reverted fix for #542. The full fix requires more time than is available before making the release candidate. 9d922de github, you mad about tabs bro? 47ed5e7 fixed tabs, commented out debugging pauses bc0f142 added more test commands to serial3 app ed40ffc compiled wiced libraries with interruptable AP join. 8182282 added `PARTICLE` define to all builds as part of #421 6874c11 update changelog with recent fixes 073f331 updated electron test firmware and pmic library de1ca0a attachInterrupt() fix for electron's C0 pin 94bcb08 P1 has normal RF switch logic 76be005 TEST=wiring/no_fixture fail fix (should pass now) 0ee169c fixes #542 - register a callback handler with WICED but also double check that the socket hasn't already been disposed of. There is a race condition inside WICED where the dispose callback is called after the socket has been deleted. f6be5b2 wlan_connection_finalize() is now fully cancellable - either when joining the wifi network or retrieving a DHCP allocated IP address. This will make the setup button more responsive when connecting to WiFi. b67fd7c WICED libs updated with cancellable network connect and `wiced_wlan_connectivity_initialized` function. a8912ca if write returns an error code, stop writing. Return a positive (non-zero) result if data already succesfully writen, return the error code is no data was written. 3ab6ef7 close the TCP client socket using both available methods in WICED. Fixes #536. 46e6133 Stop existing TCPServer before trying to create a new one. 63943d7 Clean up any existing connection in TCPClient/TCPServer. Prompted by issue #538 79e7438 Calling WiFi.connect() when the system was connected to the cloud caused a green LED. Fix is to add additional checks that WiFi isn't already connected. 5e93e30 only delete sockets that were in the list. This ensures that when the system closes sockets (e.g. when WiFi is taken down) then a subsequent client calling socket_close() won't cause a double-delete. c9c3436 re-instate socket dispose now that the double-free problem in wiced_delete_tcp_socket is worked around. 683d4ea `STARTUP()` macro as a convenient way to declare code that executes very early in the startup process. 8f417c6 fix for recursive definition of TARGET_PATH when specifying APPDIR dfa55cc additional unit tests f647661 allow the RGB.onChange handler to be removed. Note that this presently causes a memory leak. 5c4912d fixup unit tests, removing compiler warnings and test errors. 0f742b8 `System.freeMemory()` API 73ddc6d `Spark.` --> `Particle.` 2fa9708 Merge pull request #539 from munirent/feature/wiced-tcp-connect-crash-fix 5417ffa Cleaning up the gettingstarted.md documentation :pencil2: 687f67b Add I2C…
