    tr8plus

    The on-board Cortex M0+ Kinetis MCU on Trizeps8Plus type modules is used for following functions: resistive touch, adc inputs, gpios and reset control with bootmode selection. It may be also used for realtime processing and power-management.
    It is capable of reading multiple 16bit analog inputs (i.e. to emulate a resistive touch controller).

    Programming

    The MCU may be programmed through JTAG using connector J401 (see datasheet for details) or in system through I2C. In-System-Programming through I2C has not been verified yet.

    Firmware

    Customers may request access to the source-code of the firmware to modify it for their needs.
