This code, partially generated by Copilot, does only print "="At the same time, I do see that the device PB6(SCL) and PB7(SDA) recieves packets adressed to it, requestng data. #include <Arduino.h> #define I2C_ADDRESS 0x0B volatile int x = 0; volati...

Please see:https://github.com/stm32duino/Arduino_Core_STM32/issues/2585#issuecomment-2517922666 I am stuck, being unable to use the device as a I2C slave.

I connected this resonator https://jlcpcb.com/parts/componentSearch?searchTxt=C341522 And the code runs. - however - USB fails to enumerate.If I upload the same code to a BluePill board, the code runs *and* the USB works.I suspect it being due to s...

I am trying to flash STM32G431 (UFQFPN32 5x5) Other STM devices like x103 are flashing just fine, but this one fails.I even desoldered it from the actual project PCB, and hooked it up with the four SWD pins only, and still fail.the main difference ma...

The datasheet suggests load of 20pF .Due to size constraints, I hope to use https://jlcpcb.com/partdetail/318914-CSTNE8M00G550000R0/C341522Most 8Mhz resonators of this size seems to have 33pF

Thank you very much for a perfect answer, well spotted.I reworked the 0402 to the neighbouring (D+) track, and it works perfectly!

Thank you, I managed to get some work, and I suspect its a issue with the way I moved the G431 to another PCB to access the SWD pads (that I overheated, or gave it a thermal shock.) I did use STM32_Programmer_CLI -c port=SWD ... woth both STLink and ...

Ah, thank you - I knew about 64Mhz, but that is plenty enough, but the USB was a good point

@STOne-32 The application consists basically of the device doing AD , communicating on I2C (100khz) and serial(USB) I have simply no low frequency oscillator as there is no clock/sleep.I must say I did not even look at the option to use HSI.The d...

Thank you, will test. Startup time is not an issue, nor is the frequency precision very important.
