Tool/software:
Unfortunately I am not getting a response from the ADS131M08. I work with the Zephyr RTOS and have implemented a driver there. Unfortunately without success.
I use two different evaboards, one original TI and one from another manufacturer. When I connect the TI board, I can communicate with the device via SPI using the IDE for the ADS131M08 EVM. So I believe that the ADS works.
If I now use my board with the Zephyr driver, I get no response. The following situation, I now reset both Evaboards, my µC board and the ADS131M08Eva. After booting, my EvaBoard sends the first command directly, it should read the ADS131M08 ID, as a response I expect a response 0x28 in the second telegram, but nothing comes at all. I have already tried several clock frequencies, 1MHz, 4Mhz and 15MHz, nothing.
What could be the reason for this? The SPI is configured as master and with CHPA= 1.
