Re: [Black STM32F407VET6] Pin map

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

Re: Serial - bit banging

What is wrong with the code? How can I set the M bit in the UART control register Ok, I've found the mistake... d1 = u1.read(2) I need to read 2 chars to all 9 bits. ;-) But I still don't see the wakeup bit. How can i do it? Ok I have not yet ever needed to use 9 bit UART so had to do a bit of goog...

Re: Send Data from XBee3 Module to PC via USB Cable

I have done this via USB myself. On the PC I opened a serail port on the USB like this https://pyserial.readthedocs.io/en/latest/shortintro.html Then on the Micro-python MCU I attached a URAT to serial converter like this 1 https://www.aliexpress.com/item/1PCS-CP2102-USB-2-0-to-TTL-UART-Module-6Pin-...

Re: SPI hardware

I am not sure what port of MP your using but check if the CS pin is going low or not as the main supported method for pin control is cs.value(0) or cs.value(1)

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

I was wondering if anyone had implemented it in the firmware with a FAT system so that the standard python file handing functions could be used Not a firmware, but an integration into the MicroPython VFS via Python: https://forum.micropython.org/viewtopic.php?p=22478&sid=134947f7ca978bac7192910b0e7...

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

Do you know if the the external Winbond W25Q16 16Mbit SPI Flash is implemented in MP? https://github.com/SpotlightKid/micropython-stm-lib/tree/master/spiflash Thanks for that. I see this is implemented in python and can write and read to the flash and this makes it use able. I was wondering if anyo...

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

@OutoftheBOTS_ it looks very similar to the other black boards, only slimmer. I’d start with this one: https://github.com/SpotlightKid/BLACK_F407ZG Thanks that looks like it is very similar setup to my new board. Do you know if the the external Winbond W25Q16 16Mbit SPI Flash is implemented in MP? ...

Re: Serial - bit banging

The STM32F407 MCUs have 5 UARTS (3 x USART and 2 X UART). I prefer the STM32F407VGT6 with 1 mb of flash on the MCU and this board has another 16M-BIT of flash on a separate IC and is under $10US https://www.aliexpress.com/item/STM32F407VET6-STM32F407VGT6-STM32-System-Board-Development-Board-F407-Si...

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

I've created stmhal board definitions for these two generic unbranded dev boards from China, labelled STM32F407XX. For lack of a better name, I've simply called them BLACK STM32F407xx. Originally located at: https://github.com/mcauser/micropython/tree/black-stm32f407 Now, moved to their own repos: ...
