I’ve been experimenting with a few circuits to find out that the accuracy of the analog inputs varies a bit.
To make a simple case, I’e attached one of the analog outputs to 4 of the inputs and read the voltages:
DA1 out set to full at 10v
Digital Meter: 10.05
AD1: 997
AD2: 990
AD3: 1003
AD4: 994
Is this a result of poor assembly or is this to be expected? I could always create a table to pad these values in the software, but it seems that I should not have to do that.
Thanks
