Part Number: ADS1263
Other Parts Discussed in Thread: ADS1247, ADS1235, ADS1248

Tool/software:

Greetings,

I have bought ads1263 waveshare module via online shop. I have connected the module with raspberry PI board for easy power connections and for spi communication i am connecting it with my stm32 board.

The issue with me is while reading register it always sends me 0xFE. I have checked all my spi connections and code as i have already worked with ADS1247, ADS1248 and ADS1235, but in this ic i am stuck. Any help will be highly appreciated.

Thanks.

    Hi Nimit Vachhani,

    Can you please send us logic analyzer captures that show the communication between the ADC and the controller? We need to see the CS, SCLK, DIN, DOUT, and DRDY signals. Please make sure the timing information is provided as well as the plots are clearly labeled

    Can you also send us your register settings?

    Finally, note that TI does not directly support the waveshare boards. If you have an issue with that board you must reach out to the manufacturer.

    Well Bryan,

    It turned out that my STM32 board had spi issues. It worked with another board and working fine with RPi. Thanks for post and sorry for trouble.
