Hi, Igor,

Thank you for reply.

Do you mean hardwear trigger is only for touch screen?

There is a description of touch screen in reference manual Chapter 54 Touch Screen Controller (TSC).

Hi Sugiyama

answer was provided for ADC hardware trigger.

>However, i.MX6UL/ULL support touch screen function with ADC. Is it right?

Touch screen function with ADC is supported.

Touch screen function with ADC hardware trigger is not supported.

From sect.51.2.2.5 ADC-TSC co-working i.MX6UL Reference Manual :

"TSC starts ADC :
TSC sends two signals: trigger and hardware trigger select signal: HWTS[4:0]."
