DS18B20 on STM32F103C8

Hi All,

I'm building a project of motorcycle computer like device. It displays some important informations for bikers. It works on Arduino Nano but Nano was too slow. Now I'm trying to port it to stm32. Almost all works fine but I have a problem with OneWire library. I would like to use DS18B20 temperature sensor but it require OneWire library. Unfortunatelly it doesn't work with my STM32F103. During compilation it returns error that it can't be compiled for this type of board. I saw OneWireSTM library in Arduino IDE but how to use it instead classic OneWire? Should I change definition in DS18B20.h file from onewire.h na onewirestm.h? What about declaration or initialization? Should I use onewirestm.begin (); or other? Or maybe there is a modified version of classical library. Did someone has the same problem? Could you please help me withthat?

Best regards and Merry Christmass,
Greg.

Hi, which core you used? I guess you used libmaple core ?

Which board have you selected in Arduino IDE?

Hi,
I use STM32F103C8 "black pill" board with 64k memory. In board manager I've selected STM32F1xx/GD32F1xx boards ver. 2020.12.17 by stmduino and use Generic STM32F103C series with ST-Link programmer. My program works well without OneWire.h and DS18B20 libraries and commented all lines which use these libraries but if I uncomment them and libraries, I receive error.

You should use in your sketch

Code: Select all

#include OneWireSTM.h
as shown by this example: https://github.com/rogerclarkmelbourne/ ... rature.ino

can we use this OneWireSTM library if our core is Arduino_STM32 core (not the rogerclark one)?

Fot STM32 core use the standard OneWire library.
