The T-Watch uses the FT6236U touch controller to detect touch input. This task involves reading touch coordinates and displaying them.
Implementation Guidance
– The FT6236U communicates over I2C. Note that its I2C address (0x38) is not always clearly listed in the datasheet
– Use an interrupt-driven approach to detect when a touch occurs, rather than continuously polling
– Keep your touch interrupt handler minimal, similar to other interrupt patterns in this project
– Ensure you’re correctly parsing the x and y coordinate bytes from the controller’s registers
