Hello CYPRESS Community,

We use the CYAT81688 Touch Screen controller and we received the linux driver "TSG6_Driver_Reference" wrotten to manage the CY8CTMA1036/768/45 Touch Screen controller.

Does this driver also useful for managing the CYAT81688? If no, where to download CYAT81688 touchscreen linux driver source code?

where to download developpement guide documentation for the CYAT81688 (registers, functionnel mode, read position,....)?

when dumping the CYAT81688 registers via I2C, all registers are 0x01(It is as the CYAT81688 stay on this boot mode)

Can you help me please ?
