Hello,I am coming to you because I have a rather difficult issue to identify.I have a screen mounted on I2C that originally communicates with an Arduino board via its address 0x3C. I have verified that I can communicate with this address using my Nuc...

The resistors are with the level shifter. And it works perfectly on other mics. 33 to 5V and tolerates 5V to 5V.We can isolate this problem.

Yes, I know, like all compilers.But in general, that of ST is still verbose. And there, nothing...However, randomly the variable res does not remain null!

Thank you very much.Thank you for the link. Very interesting.My signal is well routed, since we see it appear with a SCL and a SDA with pinoches configured by cubeMX.The screen has already worked under STM, but not in a correct and durable way. I did...

Good morning,Thank you for that answer. I started by doubting the hardware, as you do. The steps I followed to conclude on a different problem from the hard are:- Disconnect the display and both resistors (real and physical connected)- Reconnect the ...

I’m trying to understand. 0xE0 is supposed to contain 0x00 + 0x38 -> but then, is it the HAL that combines the two pieces of information? Is it one address per pointer?You’re completely losing me with your answer.
