Hi,
I tried checking the ADS7138 in manual mode, it works fine.
However in case of auto-sequence mode I have issue with ADC register read. I m trying to read 16 registers from 0xA0 to 0xAF. I have configured ADC register value with Channel ID. My data is getting shifted, sometimes I get Channel ID 0 data in 0xA0 and 0xA1 register but sometimes I get Other channel ID data in 0xA0 and 0xA1 register. Kindly suggest solution for this issue.
Kindly suggest.
Hello,
When reading register data, you should not be getting any Channel ID info in your SDA.
There are two methods to read register data, a single register read, or a continuous block, shown below. Either method needs 8 bit frames, which means there is no ADC measurement data involved. This indicates that no Channel ID data would be included.
Would you include a scope shot of the entire read register transaction, this would be a minimum of three frames
