DWIN displayinteracts with MCU
1) Arduino (esp32 and STM32 are also available) communicates with DWIN screen serial port through 82/83 protocol. After power-on, MCU sends boot information, and sends instructions to make DWIN screen buzzer beep once at the end;
2) DWIN screen user database function demonstration: the saved data will not be lost when power is off, and the instructions sent by MCU are re-read to the VP address of the screen when power is on.
3) DWIN screen C51 function demonstration: including login password, sidebar slide-out menu, and screen saver function.
