This repository provides a C library and accompanying resources to facilitate communication between STM32 microcontrollers and DWIN DGUS-II UART displays.

• Modular Design: Easy integration into existing STM32 projects.
• Advanced STM32 UART: Uses DMA transfer and Idle Line Detection of STM32 uart peripheral.
• API for display update callbacks: Uses callbacks instead of polling display VP addresses.
• Example Project: Ready-to-use STM32CubeIDE project to kickstart development.
  • MCU: STM32L431VCT6
  • Display: 7" COB UART Touch Panel (DMG10600T070_09WTC)
• UI Tools: DGUS and GIMP project files for customizing display interfaces.

• Hardware:

  • STM32 microcontroller development board.
  • DWIN DGUS-II UART display.
  • ST-Link Programmer for flashing the microcontroller.
  • USB-to-UART TTL converter or SD card for updating the display.

• Software:

  • STM32CubeIDE
  • DWIN DGUS Tool
  • GIMP or suitable image editor.

1. Clone the Repository:

   git clone https://github.com/alexantony13/dwin-stm32.git

2. Open Example Project:

   • Open STM32CubeIDE.
   • The exapmle project is located at exapmles/STM32CubeIDE/dwin-stm32-testing.
   • Open the example project using File > Open Projects from File System... menu option.
     • Note: The library is added as a linked source folder.
   • Open dwin-stm32-testing.ioc file and review the UART, Clock and GPIO settings.

3. Build and Flash:

   • Compile and flash the firmware to your STM32 board.

4. Load DGUS Project:

   • Open DWIN DGUS Tool.
   • Open the example project: examples\DGUS\dwin-stm32-test.
   • Upload to the display

5. Connect display and STM32 uart pins:

   • Connect STM32 UART Tx to Display Rx
   • Connect STM32 UART Rx to Display Tx
   • Connect STM32 GND to display GND
   • Use level shifters if needed. (If stm32 uart pins are not 5v tolerant.)

• API for writing data to VP addresses.
• API for registering display event callbacks.
• API for reading data from VP addresses.
• Implement CRC handling.
• Add utility functions for display manipulation.
