FT81x Block Diagram FT81x with EVE (Embedded Video Engine) technology simplifies the system architecture for advanced Human Machine Interfaces (HMIs) by providing support for display, touch, and audio as well as an object oriented architecture approach that extends from display creation to the rendering of the graphics. Serial Host Interface By default the SPI slave operates in the SINGLE channel mode with MOSI as input from the master and MISO as output to the master.
TFT Timing Characteristics Shown below are the FT81x registers that control the TFT’s timing (clock and sync signals), along with the values recommended to use for this EVE2 TFT Module: Horizontal Timing Vertical Timing Clock Settings Register Value Register Value Register Value REG_HSIZE...
Touch-Screen Engine The Capacitive Touch Screen Engine (CTSE) of the FT813 communicates with the external Capacitive Touch Panel Module (CTPM) through an I2C interface. The CTPM will assert its interrupt line when there is a touch detected. Upon detecting CTP_INT_N line active, the FT813 will read the touch data through I2C. Up to 5 touches can be reported and stored in FT813 registers.
