The hardware setup is done using CubeMX to create the project with AzureRTOS threadX enabled on both cores. The DCMI, LTDC and DSI are also configured from CubeMX. USBX host for mass storage device is enabled on M4 core.

A camera module needs to be attached to the main board.

• M4 will : 0. Start DMA on DCMI in continuous mode

  1. toggle the orange LED twice per second using 1 tx thread
  2. restart DMA when the frame complete event is received from DCMI, write some things on the UART once per second using 1 tx thread
  3. read data from I2C4 and put the retrieved data in shared memory for M7 using 1 tx thread
  4. initialize USBX and FileX, try to mount a USB device and write some test data

• M7 will :

  1. toggle blue LED once per second; retrieve touch screen data from the shared memory wrt attached touchscreen and post PEN events for guix
  2. start guix using 1 tx thread - a few GUIX items are displayed
  3. write some status messages on the display once per second

GUIX was added as a git submodule

The display is generated from GUIX Studio
