[Black STM32F407VET6] Pin map

[ProudPagan]

Hi,

I am looking for the MicroPython pin name <--> board pin name (PX-## etc.) mapping for the
Black STM32F407VET6.

Could anyone point me to that?

Thanks

I found a blurry photo of that board, looks like they're labelled with their "CPU" names (like you say -- P<port><num>).

The easiest way to use them is machine.Pin.cpu.<port><num> (or machine.Pin('<port><num>')

[jimmo]

Which board definition are you using? If it's https://github.com/mcauser/BLACK_F407VE then it should even just work directly using what's printed on the board as e.g. machine.Pin('PA10') or machine.Pin.board.PA10

Can you run dir on machine.Pin.cpu / machine.Pin.board (this is the output for my Pyboard 1.1 for comparison)

Code: Select all

>>> dir(machine.Pin.cpu)
['__class__', '__name__', 'A0', 'A1', 'A10', 'A11', 'A12', 'A13', 'A14', 'A15', 'A2', 'A3', 'A4', 'A5', 'A6', 'A7', 'A8', 'A9', 'B0', 'B1', 'B10', 'B11', 'B12', 'B13', 'B14', 'B15', 'B2', 'B3', 'B4', 'B5', 'B6', 'B7', 'B8', 'B9', 'C0', 'C1', 'C10', 'C11', 'C12', 'C13', 'C2', 'C3', 'C4', 'C5', 'C6', 'C7', 'C8', 'C9', 'D2']
>>> dir(machine.Pin.board)
['__class__', '__name__', 'LED_BLUE', 'LED_GREEN', 'LED_RED', 'LED_YELLOW', 'MMA_AVDD', 'MMA_INT', 'SD', 'SD_CK', 'SD_CMD', 'SD_D0', 'SD_D1', 'SD_D2', 'SD_D3', 'SD_SW', 'SW', 'USB_DM', 'USB_DP', 'USB_ID', 'USB_VBUS', 'X1', 'X10', 'X11', 'X12', 'X17', 'X18', 'X19', 'X2', 'X20', 'X21', 'X22', 'X3', 'X4', 'X5', 'X6', 'X7', 'X8', 'X9', 'Y1', 'Y10', 'Y11', 'Y12', 'Y2', 'Y3', 'Y4', 'Y5', 'Y6', 'Y7', 'Y8', 'Y9']

An observation:

Code: Select all

machine.Pin.board.LED_D2.off()

turns the LED on! Same with

Code: Select all

machine.Pin.board.LED_D2.value(0)

Then most likely the LED anode is connected to Vdd, such that it requires a low level to shine.

I see.

The header directly opposite to the JTAG connector is marked "For mcudev/TFT" -- looks like the parallel LCD bus... is this documented somewhere?

I found all the GPIO pin mux in ports/stm32/boards/stm32f405_af.csv. This is referenced by boards/BLACK_F407VE/mpconfigboard.mk.

stm32f405_af.csv contains ports PF## through PI## which don't show (are not available?) in MicroPython.

Thanks

The TFT header is a copy of the needed pins on the side to use the 16bit parallel FSMC peripheral.

U can find the TFT pin-out here https://wiki.stm32duino.com/images/a/a8 ... AG-TFT.pdf

And here is a pic of the pins used but the MCU for the FSMC peripheral

Thanks, that PDF is what I was looking for!

[mcauser]

There are also pin diagram images here showing which pins are on the TFT header:

Great, thanks.
