Solution verification board for touch chip TTP224B

This project is used to verify the solution verification board design of the Lichuang Mall microcontroller touch chip TTP224B ( product number: C94149 ). This project is  a sample project for the Solicitation Order for Lichuang EDA open source hardware platform solution verification module . 

TTP224B is a touch IC designed using the capacitive sensing principle. Provides four input ports, and four direct output ports.

In order to facilitate debugging and different needs, this verification version can use jumpers to meet different needs.

1. Eight output modes can be selected by soldering jumpers (J1, J2, J5).
2. The trigger mode (single-button trigger, or multi-button trigger (can be changed to sliding trigger after programming by microcontroller)) can be selected by welding the jumper (J4).
3. The triggering effect (i.e. whether to self-lock) can be selected by welding the jumper (J6).
4. You can select the working mode (low power consumption, and fast trigger) with different requirements by soldering the jumper (J3).
