Refer to Hardware
folder. The board is drawn by Altium Designer 21.
The hardware circuit design refers to the open source project of mightyohm.
Refer to Firmware
folder. The firmware is based on Arduino platform and PlatformIO IDE. The demo runs on a stm32 board and a ssd1306/ssd1315 oled screen. You can modify the pins of the OLED screen and the external interrupt pins of the counter by modifying the pin definitions at the beginning of the program to migrate to other boards that support Arduino.
