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
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.

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. I need these
sensors to shoot data concurrently, while I think this board, allow only
one signal at time, unless you switch input
http
Maybe you need more ADC chips .
I dont know how to use gpio as as analog reading , As I understand , GPIO
only get 2 level input 1 or 0 , and if your analog signal over 2 levels
,how to measure ?
Another idea is
use TDM switcher , maybe you can find some chip can do switch several ADC
input and 1 o
Was wondering how many of the GPIO I can use for analog reading. I have
many sensors that output only in analog; so I was wondering if that may
work, since the BBB has only 7 Analog IO, while the rest are all digital.
If I can't plug more than 7 analog IO, how could I plug in more? Thanks.
