Mini 2440 , How to use ADC pins on GPIO
Hi My Friends ,
I have a ARM 920T based board called Mini 2440 . Qtopia is installed on it . I am developing app by using QT programing language . I have made simple app . My app reads analog value from pre -installed pot on Mini 2440. This is Okay . App works well . Pot is conneccted to AIN0 pin on GPIO as default . But I want to use AIN1 pin . Because I will connect a device that generates analog signal.
I read file dev/adc for AIN0 , but ı can't access AIN1!. How to solve this problem . İs There any idea for this problem. Thanks Already .
