Reading from digital pins

[renderit]

Hey great work with this! As I understand you can read the analog pins(analog sensors) with this module.. Is it possible to read from the digital pins(PWM) of the High precision board as well--which is a DAC8532 as shown on the wiki?

Hi renderit,

As the onboard sensors on the analog pins currently returns voltage readings on ADC channels 0 and 1, it's only necessary to change the jumpers on the board to read them as single ended readings instead of something wired externally on these channels.

About the PWM: you have tested what you need with the DAC8532's C sample code that comes with the oficial C lib ? It's here: http://www.waveshare.com/wiki/File:High-Precision-AD-DA-Board-Code.7z

If it works, then yes ! It's possible to implement on Python library, because it's a wrapper that works with the original C code. Currently, i've based on the C example "ads1256_test", so it's necessary to add a wrapper to the DAC8532 sample code too.

Hi fab,

Great Work! May I know the procedure that you followed to create the wrapper for ADC, since I need to create the same for DAC8532 as well!
