MicroPython board definition files for the MCUDev black STM32F407VET6 dev board.
Brand: MCUDev
Markings: STM32F4XX STM32_F4VE V2.0 1509
You can buy one for around $16 AUD (Oct 2019) on AliExpress.
Clone the board definitions to your MicroPython ports/stm32/boards folder.
cd micropython/ports/stm32/boards
git clone https://github.com/mcauser/BLACK_F407VE.git
cd ..
make BOARD=BLACK_F407VEThis board can be flashed using DFU. To put the board in DFU mode, disconnect USB, set BOOT0 to ON by connecting pin BT0 to 3V3 and reconnect USB.
Now you can flash the board using USB with the command:
make BOARD=BLACK_F407VE deployOnce the upload is complete, disconnect USB, set BOOT0 to OFF by connecting pin BT0 to GND and reconnect USB.
Alternatively, you can use the MicroPython command pyb.bootloader()
to get into DFU mode without needing to use the switch.
Currently, you need to unplug and replug the board in order to switch from DFU mode back to regular mode.
Once built and deployed, you can access the MicroPython REPL (the Python prompt) via USB serial.
