How to use

• The e-paper libraries are based on HAL and you can migrate them to other STM32 boards with STM32CubeMX.
• The projects are built in Keil V5.

1. open the project /stm32/MDK-ARM/epd-demo.uvprojx by Keil V5.
2. click "Build" to compile the project.
3. click "Download" to download the program to your target board.

How to migrate the project to other devices

1. open the .ioc file with STM32CubeMX.
2. set the toolchain/IDE (MDK-ARM V5 is recommended).
3. generate source code based on user settings.
4. open the project in the IDE.
5. add the directories BSP/Fonts to the project.
6. build the project and download it to your STM32 chip.
   • this project is created on STM32F103ZE but you can migrate it to your own chip, see the .ioc file.
   • for other chips, you may have to edit the epdif.h and change this line #include "stm32f1xx_hal.h" according to the target chips.
