[AM335x]Linux examples to work touchscreen driver and adc driver together

Sung-IL

Dear Champs,

Could you please let me know how the touchscreen driver and ADC driver should be configured to work together?

In long touch scenario on touch screen, My customer found touching was discontinued when there was ADC input although they want to make usecase for long touch and short touch separately.

I think it can be achieved if 2 FIFO buffers connected to touchscreen driver and ADC driver at each and MFD driver was used, right?

Could you please provide more details how they can achieve to work touchscreen driver and ADC driver together?

Thanks and Best Regards,

SI.

Hi SI,

This is the wiki resource: http://processors.wiki.ti.com/index.php/Linux_Core_ADC_User's_Guide

Thanks,
But it seems this is explaining only ADC driver implementation, and did not explain how ADC can be worked with touch screen driver.
They found touching on touch screen was blocked by ADC input as I described before although they referenced this wiki already.

Thanks and Best Regards,
SI.
