MicroPython Forum

Hi Forum Admins,

Is it time to split Other Boards forum into a few port specific forums?
STM32, NRF, PIC, SAMD etc?
So it more closely matches ports in the MicroPython repo?

The unpopulated U3 pads on the bottom is for a W25Q32JVSSIQ 32M-bit SPI flash, according to the datasheet

YXZhu has already made board definitions for both the F401 and F411 boards: https://github.com/YXZhu/micropython/tree/master/ports/stm32/boards/WeAct_F401CC https://github.com/YXZhu/micropython/tree/master/ports/stm32/boards/WeAct_F411CE STM32F401CCU6 and STM32F411CEU6 download link: https://pan.bai...

Anyone using this new $7 WeAct STM32F411CEU6 board? https://www.aliexpress.com/item/4000084631884.html Comes in 2 variants: STM32F401CCU6 core board 64KB RAM 256KB ROM STM32F411CEU6 core board 128KB RAM 512KB ROM Looks like an upgrade of the old "blue pill" with a more powerful CPU and USB-C https:/...

Your link 404s. Clicking on it goes to "%5Bb%5Dhttps%3A//github.com/jczic/motor ... 49%5B/b%5D"
Try removing the "[ b ] [ /b ]".

It's coming up as 'pyboard' as that's the default for the STM32 port.

The Q1 or B1 in the schematics is the RTC battery (bottom right CR1220 lithium cell on the board). It's designed to be a backup 3V power source to maintain the RTC datetime while you unplug / plug the primary power source. Schematics are available on Github. See the links in the readme footer. https...

On boards such as the MCUDev Black STM32F407VET6 , there are 2x user buttons. In the board definition I've defined KEY0 as the main switch. Is it worth updating pyb.Switch() to support multiple switches? eg. pyb.Switch() == KEY0 pyb.Switch(1) == KEY0 pyb.Switch(2) == KEY1 Or is pyb.Switch deprecated...

Yeah, it's been working for a while now. See: https://github.com/micropython/micropython/issues/2335 You need to write esp_init_data_default.bin at offset 0xffc000, then write your firmware at offset 0x00000. This is how I got it working on my Wemos D1 Mini Pro (the older blue one): esptool.py --por...

You could try requesting it from the seller on AliExpress. Alternatively, try to find the product on Taobao.com. Sometimes they have pan.baidu.com links to zips loaded with useful into, schematics, datasheets, etc, however sometimes only in Chinese, so you need to wash through a Google Translate. Th...
