Hi,

It would really help if you shared some code. It's difficult to help you without knowing specifically what you do.

Hey Jared,

On both the SPI and UART lines, all I see is random noise. I was using a logic analyser to analyse the UART and SPI signals, and I got a framing error for UART, and the data transmitted over SPI was random.

I was able to build the project after copying over the UART example's sdk_config.h into the SPI example's sdk_config.h. Moreover, I had to add some include directories and files.

Please let me know how I can get them to work concurrently.

Thanks,

Urvaksh

Hi,

Could you describe your problem more in detail? What exactly doesn't work? Are you able to build the project without any errors? Do you see any activity on the UART or SPI lines?

regards

Jared
