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).
