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.

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: ...

Re: IR encoder pyboard V1,1

Thanks for this info I appreciate this. Looks like it is a quadrature encoder. I looked at each side of the encoder and I only see one sensor on each side.

Re: IR encoder pyboard V1,1

I have been googling most of the day attempting to understand the IR encoder and disk with pyboard https://images.app.goo.gl/aTNkSUFWzMHfjQeR8 The red wire + on the encoder is connected to a 5v power source and black wire - to ground. The disk is freely spinning between the encoder sensors. output1...
