ADC on Odroid W

BracketMaster · Unread post by **BracketMaster** » Sun May 28, 2017 2:52 pm

I recently became aware that the PIMC Ricoh module on the ODROID W has a an ADC on it, which I would like to use instead of a separate ADC chip. I cannot however find adequate documentation regarding how to access and read values from the ADC. All I found was a header file on https://github.com/hardkernel/linux/blo ... 4740-adc.h that seems to have something to do with the ADC i guess? It's not very clear. In addition, I don't have any information about the registers for the ADCs or the ADC clock-speed. Any information would be greatly appreciated. The project I'm working on is urgent and replacing separate ADCs with an onboard ADC would be a great help!

You may have to elaborate. Upon attempting to follow the instructions on viewtopic.php?f=104&t=12047, I find that I have no directory iio after /sys/bus. Also, what do you mean by search kernel source with rc5t619? Are you reffering to searching this branch? - https://github.com/hardkernel/linux
I didn't find rc5t619 there...
I am running Raspbian with Linux Kernel v4.4.50
