Hi Mike,
Thanks - My aim is to synchronize each conversion to an external source. I've taken your advice and run the ADC in ScanMode2. I'm also keeping it in Active mode so IB1&2 are always energized.
The external source is running at 22 Hz and the ODR is set to 26.83125 Hz. This means I'm sending the RESTART command for every conversion.
The sequence seems to work, since I get ADC_DOUT at the expected rate. However, after 2 or 3 conversions the OFLO_FLAGS is set to 1 and remains there for subsequent conversions (ADC_DOUT got clamped). The short circuit and rails flags are clear.
When running the ADC without sending the RESTART command (i.e just free running) I consistently get valid ADC_DOUT.
Is there a problem sending the RESTART command for every conversion?
Thanks for your help.
David.
