Tearing effect and TouchScreeen Blocking

Hi All,

I'm developping an custom board with an SPI Display (480x320 poixels).

When I enable the TE pin on display and when I managed by Stm32 by interrupt,

the touch screen stop to work because TouchControll::sampletouch(uint32_t x, uint32_t y)

is no longer called.

The IRQ trigger call touchVsync callback. TE interrupt trigger every 16ms.

What is the reason of touch screen blocking?

Thanks in advance
