Re: MCUDev Black STM32F407VET6 + STM32F407ZET6 dev boards

Wow, that's amazing, thanks for doing this! I wonder if jupyter + micropython can be shared somehow to avoid duplicating work, I seem to have typed exactly the same thing. For reference, help(stm) outputs the following (see below), so the register address is stm.RCC_AHB3ENR and FSMEN (according to ...

Re: MCUDev Black STM32F407VET6 + STM32F407ZET6 dev boards

Hello Many thanks for the code, I understand the first 2 paragraphs but I seem to be confused where this code would go, does it have to compiled in the firmware ? Regards Mike As I stated above I have only used this in C and haven't yet compiled it in to the MP firmware. My story is this I only sta...

Re: MCUDev Black STM32F407VET6 + STM32F407ZET6 dev boards

First you need to understand how FSMC works with these screens. It utilizes the 8080 ram interface, this basically has 16 data lines and 16 address lines then a few control lines(chip select, read, write). With the TFT they don't use all the address line to address the RAM but rather uses only 1 add...

Re: Neo pixel

I would always advise using ESP32 rather than ESP8266 because ESP32 is so so much more capable than the ESP8266 and is not much more to buy. I started with ESP8266 but for a number of my projects I kept hitting a wall then I switched to ESP32 and it broken all the walls I was hitting.

Re: Neo pixel

This is something that ESP32 running micro-python is able to do

Re: DEVEBOX STM32F407 mini

It is definitely a problem with the boards definitions. The board that I am using is a MCUDEV_DEVEBOX that has a STM32F407VGT6 MCU. IF I compile the STM32F407VET6 definitions here https://github.com/mcauser/BLACK_F407VE it will compile and deploy then show up as PYBFLASH If I compile the STM32F407ZG...

MCUDEV_DEVEBOX_F407VGT6 dev boards

@lukesky333 I put together these ones for the board: https://github.com/mcauser/MCUDEV_DEVEBOX_F407VGT6 - 1Mbyte flash https://github.com/mcauser/MCUDEV_DEVEBOX_F407VET6 - 512Kbyte flash Both are 100 pin LQFP chips and it looks like larger flash is the main difference. I guessed some of the pin num...

Re: MCUDev Black STM32F407VET6 + STM32F407ZET6 dev boards

I have used the the STM32F407VET6 black with a ILI9431 TFT in 16bit parallel using the FSMC peripheral but only in C but 1 could use my library then wrap it up to be called from MP. Here is a video of me using a ILI9431 TFT that I brought and soldered down to a breakout board then connected to the S...

Ok when I deploy it appears to flash the firmware although aftre flashing is finished then it gives errors see output but after I unplug and remove the boot jumper then plug it back in neither linux or windows will see it on the usb like the firmware isn't talking at all Writing build-MCUDEV_DEVEBOX...
