Application running on STM32F746G.


TouchGFX.

This project is built on the stm32f746g-discovery board. It was intended to be an diy solution to a race dash.

IDE used: STM32CubeIDE 1.3.0. Gfx tool: TouchGFX 4.13.0 Designer.

1. You need an can bus tranceiver, I have used the SN65HVD230.

1. 3d printable case is in the making.

1. Clone project.
2. Install STM32CubeIDE 1.3.0 and TouchGFX 4.13.0.
3. Open EcumasterBlackCanWithTouchGFX.IOC.
4. Click Additional Software.
5. Make sure STMicroelectronics.X-CUBE-TOUCHGFX 4.13.0 is installed and Application is set to TouchGFX generator.

• Project uses C and C++.
• To work on GFX open: project root/TouchGFX/EcumasterBlackCanWithTouchGFX.touchgfx with TouchGFX.
• Text resources in TouchGFX are set up as wildcard buffers.
• Mapping of data to screen buffers are done in MainView::updateVal(uint8_t* newValue) which you find in : project explorer/TouchGFX/gui/src/main_screen/MainView.cpp. If you are planning on extending the struct you need to do a search. Data is sent from main through a FreeRTOS queue. And handled in TouchGFX part of the code.
• Canbus input data is handled in project root/Core/Src/main.c in function void HAL_CAN_RxFifo0MsgPendingCallback(CAN_HandleTypeDef *hcan).
• Do not be afraid to experiment. Have fun!
