Hi, I want to use AIN0, for external temperature sensor, instead of pot. mini2440 doc says "remove the pot or cut the trace from the pot center pin to pin5 of CON4. But not sure how do I do this. Anyone has more information about it Thanks Tej
If you are not sure how to do that then I would suggest that you either, find someone who knows how to use a solder rework station or use another ADC input. There are other ADC inputs for general use. Search for "AIN1, 2, 3" and "Analog input (ADC)"
Yup, used AIN1 port instead, using following changes Changes in drivers/char/mini2440_adc.c , in function s3c2410_adc_open changed the value of adcdev.channel to 1. Compile the kernel and everything worked as expected. Thanks Tej
