Forum Post: RE: ADS1241 Registers

Hi Hamid,

Engineering is fun, right? It is stressful trying to get things to work the way we want, but then it is a great feeling of accomplishment when it is finished.

Here is the total process:

1. Poll DRDY (better to use a controller interrupt, but we can work with polling) and wait until it goes low
2. Write the register to change the MUX to the next input
3. Wait 4 tosc periods
4. Send RDATA command
5. Wait 50 tosc periods for results to be placed in the output register
6. Read three bytes of the result data
7. Loop back to item 1

What needs to happen as soon as possible at the end of the conversion cycle is the MUX change so that the next conversion is accurate.

I hope that explains the process a little better.

Best regards,

Bob B
