Board definition moved here:

Using @dhylands approach, with separate git repos per board, and clone them into stmhal/boards when needed

Hi. Need some advice. I bought one of this boards and confused with led light.
I used code from vcc-gnd.taobao.com for led it works. But what if i want to use cubemx?
Used Cubemx and then used simple code but it doesnt work.

HAL_GPIO_TogglePin(GPIOB, GPIO_PIN_9);
HAL_Delay(500);

Does this board work with Hal drivers? May be you can add example with hal driver?

The board works with the HAL, since micropython uses the HAL.

Did you also configure the pin as an output? and enable the clock for Port B?

Do you have a complete code example?

I have a small repository here: https://github.com/dhylands/stm32-test and if you check that out and do: then that builds a small app that flashes the BLUE Led on the board (and uses the HAL)

I set the board to DFU mode , and download the flash using:
$make BOARD=VCC_GND_F407 deploy
It worked in MACos, but met a driver trouble in Win7 X64. It can be read as a mass strorage, but the VCP cannot work.
What is the problem?

I just ordered one. And I feel a bit dirty.

Can we have a way to throw money at the project other than buying Pyboards? A donate-button would be cool, but also something that can be billed - companies need billing.

IIRC you can buy stickers to support the project.

From Adafruit, shipping them from New York to Munich

Great option to add to my next Adafruit order.

There are even better boards with [b]STM32F407ZET6[/b] for ~13-17 US$ with optional external [b]SDRAM[/b] (1 MByte IS62WV51216BLL, ~2-5 US$)

I'm not shure if MicroPython suppports external SDRAM , but it would be fantastic to run MicroPython with more than 1MB of free RAM on 15-20 US$ board

Links to documentation for many of those boards can be found in this forum:

Thank you for the schematics! The STM32F407ZET6 just replace the Arduino DUE and with the STM32F407ZET6 LCD it screams!
