Other Parts Discussed in Thread: ADS1261, ADS1255
Hi,
I'm just getting started with the ADS1261EVM; I want to pick a channel and calibrate it; I've found the SYOCAL, SYGCAL and SFOCAL commands but what do they do exactly?
Do they calibrate all channels in one go? If not, how do I pick a single channel?
Other questions are:
Does SYOCAL short the PGA inputs or is it for a full system calibration, i.e. including my external circuit?
Assuming SYGCAL does a full system calibration, what gain is it set to?
What does SFOCAL do exactly?
Do any of these commands connect in Vcom? If not, how do I do that using the commands available?
Do I need to use these commands in conjunction with others?
Do you have any script examples I can use?
Any other insight would be greatly appreciated.
Many thanks,
Elton
