Modify and program the Hanshow 2.13 inch price tag as an EPD clock.
The Hanshow 2.13 inch price tag is very interesting device. It is a small MCU system with EPD to display the price. We can re-program it to realize some new functions. The goal of this repository is making an EPD clock.
It contains:
- 2.13 inch EPD
- MSP430G2553 MCU
- 25VQ21 256KB SPI Flash
- A7106 RF chip
This branch is used for EPD Clock.
Todo List:
- Display time and date on EPD.
- Software UART.
- Configure time and date via UART.
- COnfigure time and date via RF.
Modify the hardware to add 32768Hz crystal for RTC function.
- Cut off the connection of P2.6 and P2.7.
- Connect crystal to P2.6 and P2.7.
- Connect the EPD_POW and RF_POW to P3.2 and P2.1
