This patch is for ADC touch screen , generally resistive touch screen will have 4 lines for ADC X+ X- Y+ Y-
so , this will cost 2 ADC for my understand , this round robin is just between this 2 ADC , instead of two sensors in one ADC converter. >From top thread , if you want to use over 10 sensors for ADC , you need external ADC chip . and do some communication work with am3358 If you want to have some flexable and no much than 10 sensors , what about add a stm32 ? 2014-02-14 5:01 GMT+08:00 <[email protected]>: > > > On Wednesday, February 12, 2014 8:42:27 PM UTC-5, Karl Longen wrote: >> >> DOH >> >> You make a good point...I thought that the GPIO were configurable between >> analog and digital. >> >> as ADC I've found this: not sure if it is right for me thou.
