FT5426 (touch controller )status register not reset automatically

[N Sornakumar]

Board : STM32F746BGT6

Previously I use stm32f7-discovery board, my touch controller is ft5336 it’s working fine, when I read the status register (0x02) every time ,after read it’s reset automatically

Example(FT5336):

Read status register( 0x02) = value ‘1’

After, Read status register( 0x02) = value ‘0’(goes automatically)

Same thing I do in ft5426 every time read status register(0x02), after read it’s not reset, it’s maintain previous value why ??

Example(FT5426):

Read status register( 0x02) = value ‘1’

After, Read status register( 0x02) = value ‘1’

Hello N Sornakumar,

Since the driver is different maybe your implementation of the ft5426 is not completely correct. The behavior should be explained in the datasheet.

Personally, I haven't worked with this driver. I hope someone of this community who knows about it can help you.
