Description

RP2040 (Raspberry pi pico) earlephilhower library) compatibility problem:
warning "OneWire. Fallback mode. Using API calls for pinMode,digitalRead and digitalWrite. Operation of this library is not guaranteed on this architecture.
Right!. No way to run. Don't wire any gpio. Run only on mbedRP2040 boards.

Steps Fix the Problem

open OneWire_direct_gpio.h.
just write line 445 at place of #define PIN_TO_BASEREG(pin) (0)
by #define PIN_TO_BASEREG(pin) (pin)
comment boths warning (line 442 and 455 (//#warning ("OneWire. Fallback mode...
it's work like a charm on any gpio of the Pico, Pico-Zero, and Pico W

Hardware & Software

Raspberry pi pico, W, and Zero.
Arduino IDE version 1.8.19 with earlephilhower library.
Version 2.6.3 https://github.com/earlephilhower/arduino-pico
Operating system
MacOS Sierra

use at the top #include <Arduino.h> and #include <DallasTemperature.h> for the sketch.
you can use any library from Arduino, it run with..

The https://github.com/pstolarz/OneWireNg library does support RP2040 platforms, you may want to try that instead.

Yes! your right just 25 days written. I try it and feedback the result. Problem was only to use non mbedrp2040 for this alternative onewire library. cannot use arduino.h for pin definitions. never worked except embed Cool to transmit information, that open a way to use onewire on pico picoz and pico w with earlephilhower library !! ....;) All with the great Arduino IDE and a large library easy to use. It's nice for each one who dont work on python or c++.. Thanks a lot for your work, am not really developper just using different library and test.. this is the modified OneWire_direct_gpio.h and for me it's really working dont know why, no problem. Sure, correct with a good library it' really better. you can take off my issue off and specify this location library for pico lowers...;) have a good day! This is only what I changed. no error and good dallas temperature why any gpio on the rp2040. correction is only if no board end of is detected by default. Arduino IDE 1.8.19 with earlephilhower library include arduino.h. here it's the really short working sketch. joy.

So nice. tested . really cool to use on any rp2040! Good job, nice beerware! have a fresh one! top guy! joy

Thanks for this information. I'm almost a novice so can you tell me once I open and edit the Onewire_direct_gpio.h file, How I then call it in a sketch. There is no install option listed for this library in Arduino 2.0.3. Thanks

I am having issues too. My PICO is completely becoming un-usable until I flash Nuke it.

I have tried the following boards and libraries.
Boards:

• Raspberry Pi Pico/RP2040 (Earle F. Philhower, III) - v3.2.1
• Arduino MBED OS RP2040 Boards (Arduino) - v4.0.2

Libraries:

• OneWire - v2.3.5 and v2.3.7
• DallasTemperature - v3.8.0 and v3.9.0
• Arduino_Unified_Sensor - v1.1.9

None of them work. Please read further for output logs and windows error when my PICO bricks.

I have attached the code in a zip file.
This is compilation and upload warning(Earle_Philhower board): Raspberry Pi Pico/RP2040 (Earle F. Philhower, III) - v3.2.1 ; OneWire - v2.3.7

I have tried with Earle F Philhower's board as well as Arduino Original: MBED_OS_RP2040 board.

Both of them are causing my board to brick. Windows fails to recognise the device.

I have searched the folder it mentioned and any other folders where libraries may be stored, but there are no duplicates of the libraries.

[joyfab]

Sure you have mutiple OneWire libraries (Multiple libraries were found for "OneWire.h") so it's not the good one. uninstall all OneWire libraries firth included AdaFruit_sensor may be it have. then install PaulStoffregen OneWire library.(https://github.com/PaulStoffregen) and verify this is the only one. Dont modify anything (bug has been corrected).
run dallas to check it. I work on mac but you can run windows same. If your RP2040 dont want to mount on usb UF2, you have to reboot it and re-write any correct code cause you have corrupted the firmware. It's not dead.

[chandradharkoneti]

I have manually searched for the OneWire library's duplicate. I haven't found it anywhere(Including in any of adafruit/other third party libraries).
Anyhow, I'll try uninstalling Adafruit_Sensor library and let you know if that works.

But Adafruit library is needed for a lot of my codes.

Click File > Preferences and turn on verbose output during compilation. This will cause Arduino IDE to show the full pathnames of all libraries used. It will also show all the compiler commands (a lot of text) which have the full pathnames to files used.
