Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

I guess I don't get it or I'm missing on something. The biggest issue I have seen with the "other" boards(not Pyboard, Maple, ESP, etc.) is the lack of tech support for them. Now grated some of the other boards quality is so-so(some Blue pills) but there are many that have very good build quality. ...

Re: Convert Image To Pixel Array Function

I have used both OpenMV cam and NodeMCU with Micro-Python. All RAM is linear so any array including 2d image array is stored in memory as linear bytes. You should be able to send the image from OpenMV straight to the UART without any formatting then have the NodeMCU forward it on to the web before f...

Re: IRQ SPEED

The STM32 MCUs of the PYBoard also have hardware encoder counters on their timers.

Re: How to communicate over 433mhz radio?

Using radio link requires checking of data received is correct. A simple way to do this is use a checksum. Either way it will require a 2 way link so that the receiver can send back to the sender if the checksum added up correctly before the next packet of data is sent. The exact hardware used also ...

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...
