Starterware/PROCESSOR-SDK-AM335X: Capture multiple ADC channels in AM335x starterware

Fabio Martins

Tool/software: Starterware

I have an application where I will use a Display with Touch, and I have some voltages (like the voltage of a Battery) to be read by the AD.

My question is: Can I configure the "TouchScreen Controller" to read the Touch and the voltages at the same time?

Or if I set the "Touch Controller" to trigger a reading when the screen is pressed, can not I set the Battery reading even if it is by pooling?

Thank you

Fabio,

If I understand correctly, you want to use 2 separate ADC channels? One for polling the LCD touch events and another to monitor battery voltage?

Hello Lali,

I will use the AIN0, AIN1, AIN2, AIN3, AIN4 for the 4 and 5-wire touch and the AIN5 to read the battery voltage.

Thanks,

FAbio
