[ts-7000] TS-7260 ADC calibration values

["Rekcut_Nod" <>]

Is there a way to determine how good the ADC calibration values are, or to 
recalibrate the ADC?

Running the sample code adc_7250.c, the executable tells me that the board has 
been calibrated by Technologic Systems, but the voltages reported seem 
unrealistic (e.g. channel 1 reports as at -708V, and user input 0 reports as at 
1.5V when it is grounded).

If I comment out the part of adc_7260.c where it checks if the board has 
already been calibrated (i.e. force it to NOT use the calibration values), the 
results seem more realistic (e.g. channel 1 reports as 0.808V and user input 0 
reports as 0.08V when it is grounded).

I sent TS a question about this earlier, but have not yet received a response.
