###HydraFW TODO/IDEA:

Generic:

• Add new utilities:

  • SPI for non intrusive sniffer for MISO/MOSI line (with support of /CS) => Already supported by Binary SPI mode
  • I2C for non intrusive sniffer for SDA line (with support of /CS)
  • Multimeter up to 3.3V/7.2MSPS(12bits) with logging in µSD file in real-time.

• Bootloader idea using official HydraBus (bootloader) OpenMoko USB ID:

  • USB DFU boot like implemented in actual firmware by keeping UBTN pressed during power ON.
  • Read a configuration file from SDcard(if present) and boot a custom firmware from SDcard(execution in SRAM).
  • other idea TBD.

• Protection/Debug features(for developer):

  • Implement basic stack overflow/underflow check with canaries between each stack (probably need chibios patch)
  • Implement advanced stack overflow/underflow protection using M4F MPU

To be checked depending on latest ChibiOS v16.1.4 or v16.2.0 USB CDC driver performances.

• Implement new USB stack(replace the one from chibios) based on STM32Cube USB Host/Device
  • Implement for USB1, USB Composite with:
    • USB CDC(for terminal)
    • Raw Bulk IN/OUT(used for binary mode)
  • Implement for USB2, USB Composite with:
    • USB CDC(for terminal)
    • Raw Bulk IN/OUT(used for binary mode)
    • Mass Storage (using microSD card)
  • Implement Ctrl-C Abort which work like UBTN press to stop waiting.
• Implement new SD card driver(replace the one from chibios) based on STM32Cube HAL
  • Implement detection & setting of high-speed microSD, in order to set frequency to 48MHz (instead of default 24MHz).
  • Check possibility to avoid IRQ and use DMA for microSD access in order to use microSD to read/write during real-time task (SPI/UART/I2C sniffer, read ADC, read GPIO, NFC sniffer/log...)
• Implemente Binary Mode (Raw Bulk IN/OUT):
  • In Firmware for USB1 and USB2(using Raw Bulk IN/OUT dedicated to binary mode) supporting SPI, I2C, UART.
  • In Host tools(Windows/Linux... using libusb) to communicate with binary mode SPI, I2C, UART.

HydraBus specific:

• Use "SPI1", "UART2" etc instead of 1/2 when specifying device to use the same for "DAC1" & "DAC2"...
• Generate DAC output advanced mode using waveform and DMA to generate Sin, Square ...
  • Add Offset and Frequency parameter for waveforms.
• SD commands:
  • New feature: Replay some terminal commands from a specified sd file, command name TBD
• i2c:
  • Slave mode
  • Number of bits (7, 8, 10)
• spi:
  • Number of bits (any number)
• Measure frequency (from 1282Hz to 84MHz, 128Hz to 8.4Mhz too, autorange ...)
• Waveform generator
• New modes:
  • Parallel Bus (2 to 32bits) with mode sniffer, read and write (with option to log data in realtime to MicroSD) (depending on feedback)
  • 1 or 3 Wire with mode sniffer, read and write (depending on feedback)
  • Basic Scope up to 3.3V and up to 7.2MSPS/12bits
  • Nand Flash x8 and x16 support (see Nand support #12)
• USB 1.x/2.0 LS/FS sniffer mode (using special passthrough mode with logging directly to MicroSD) (see USB sniffer capability #21)

HydraNFC specific:

• Cleanup files trf7970a/src/trf797x.c & trf7970a/src/trf_spi.c and change license to Apache 2.0
• NFC:
  • Scan:
    • support 10-byte UIDs (If someone find Tags with 10 bytes UID)
    • implement real anti-collision (be able to detect 2 tags)
  • Sniffer:
    • real-time write in SD card to sniff during ultra long session (limited by SD card file size and not by the internal 64KB buffer)
    • add optional timestamp global and relative(between data) with at least 73.75ns resolution(for 13.56MHz)
    • Mode for ISO14443B and ISO15693 or lot of other mode TBD (raw specific mode)
  • Emulator mode (Card Emulation) is planned and lot of other modes TBD (like raw mode to modulate even proprietary protocol on 13.56MHz)

###Hardware Extension/Shield

• Extension using EEPROM:
  • Implement support of EEPROM extension detection with same hw & content as Beagle bone defined here

###Development Environment:

• Tutorial for EmBitz to load project and debug it (Windows only)
• Tutorial for Eclipse/ChibiStudio to load project and debug it (Windows only)
• Tutorial for Eclipse to load project and debug it (Linux)

###DONE (please test with HydraFW v0.6):

• CAN1 and CAN2 with HydraOBD Shield
• JTAG (with different MCU/CPU and report what work what do not work ...)
• 2-wire (I have tested mainly the write with different speed need to check the read ...)
• Logic Analyzer mode (to do more tests)
• I2C binary mode to be tested
