How to get access to the ADC on dm365?

Josep Bernardo Clari,

Please refer to the DM365 EVM Technical Reference document located at:

http://support.spectrumdigital.com/boards/evmdm365/revc/

Page 2-23 describes how each ADC_CHx is connected and the Test Point (TP) to access the corresponding value.

ADC_CH0 => CCD_PSMON, ADC_CH1 => VCC_3V3, ADC_CH2 => CPU_VCC_1V8, ADC_CH3 => VCC_1V2

ADC_CH4 => TP37, ADC_CH5 => TP36

The DM365 schematic (page 11) will show the pin number that is associated with the ADC_CHx

E8 => ADC_CH0, B7 => ADC_CH1, A7 => ADC_CH2, D8 => ADC_CH3, D7 => ADC_CH4, A6 => ADC_CH5

Thanks for the reply Marcus, but I know how to get physical access to the pins.

We need know how to get access in software. That is, the library to obtain the value of the analog signal with the software.

Thanks

Josep,

The following thread discusses this topic.  I will move this request to the linux forum; perhaps someone from this forum

familar with the ADC driver can provide additional information.
