I showed that i was writing 0xFF to MUX0 then reading it back. I put a breakpoint in the WReg() and RReg() functions in order to capture this. I never see the data buffer in RReg coming back with...

Hi Tim, That is your code information. Interpret for me the 16 SCLKs you showed in your last scope shot. Either the RREG or WREG command requires 24 SCLKs. The last thing you send to the ADS1248 is...

The 16 SCLKs are controlled by the STM32H HAL SPI functions whenever i do a Transmit/Receive. I wasn't trying to send a NOP, just Write 0xFF to MUX0 and read it back. The ADS expects the SCLK phase...

Hi Bryan, Sorry, I have one more question on this topic. Regardless of the magnitude of the load regulation error, wouldn't the ratiometric measurement remove it anyway? -Drew

Hi Drew Nakamura, Yes, the ratiometric measurement should theoretically reduce the error due to shifts in the VREF voltage -Bryan

Hi Tim, You would have to check the datasheet for the processor to know whether CPHA should be 0 or 1. As it is currently wrong on the scope shots and you are using 1 then it must be 0 instead. As far...
