Select Channel for /dev/adc
Posted: Mon Jan 16, 2012 8:34 pm
Hello, is it possible to select the desired analog input? /dev/adc simply returns the value of AINT0, but I also want to access AINT1, AINT2, ...
I know it is possible to perform this by writing to rADCCON:
2440addr.h:
#define rADCCON (*(volatile unsigned *)0x58000000) //ADC control
but I want to select the input within Linux.
Thanks in advance.
