Hello,
We are currently trying to get the ADC measurements from all 16 channels from ADS7953 chip - we are using ADS7953EVM board for testing purposes.
I tried to use the driver in Auto 1 mode, so the sent sequence looks like this:
- 0x8000 - enter Auto 1 program mode
- 0xFFFF - use all ADC channels
- 0x2C40 - send Auto 1 mode configuration
- 0x0000 in a loop - continue operating in Auto 1 mode
Here is the screenshot of all signal from logic analyzer:
If I understand the datasheet correctly, the ADS should be sending measurement data starting with 4 address bits and 12 data bits.
Could you please me if this situation is caused by wrong MOSI data, or is it some other problem?
Best regards,
Przemyslaw
