Hi everyone!It's my first post and I'm trying to make something with the SPI but I met the problems. Even if I configure the interface (hopefully correctly), I can't communicate with any SPI device. I bought BMP280 as a simple sensor to communicate w...

@TDK You're right. The other pin works well with 2MBit/s. It doesn't matter how I set the pin frequency. How did you know that? Is the 2V value with resistors related? Or only because of capacitance?

I got an oscilloscope and here's the result and other Logic Analyzer. Conclusion:- Peaks came from a probably broken Logic Analyzer. Something was wrong internally, maybe just separation between channels.- I noticed that every module I tried to use h...

I tried swapping pins but as "expected" - one channel is broken. After the weekend, I will try a different logic analyzer and then consider buying a new board. I'll let you know about the results. Thank you!

Sorry, but I forgot about it before. Switching SCK also results in MOSI peaks.I'm using Nucleo-H743ZI2 (NUH743ZI$AT3). I looked at the schematics before I posted (schematics). Nothing is connected to PC2/3 or PD3. PD3 can be used with USART as a CTS ...

My previous answer in measured without BMP connected. Only the logic-level analyzer and board.@Sebastiaan I decided to use registers instead of HAL because I had the same problems with it so I thought maybe something was wrong with SDK.I have changed...
