Hello, I tried to make this module as simple as possible to try and understand how to use mp_hal_delay_ms() in a native module. It's just a wrapper called mydelay. So I have these two files (based on the factorial example ). mydelay.c and Makefile as follows: // Include the header file to get access...

@holberg, thank you for your efforts, this is definitely going in the right direction! Just a note about viper magic, I tried this for fill() instead of your code: import utime import machine LCD_REG = const(0x60000002) LCD_RAM = const(0x60080002) @micropython.viper def fill(n: int): width=320 heigh...

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 t...

Hey @OutoftheBOTS_ a native solution based on your C code would of course be the best solution, but would a micropython implementation be fast enough to get started? I've been playing with jupyter notebook + micropython remote ( + vim-binding ) and have started converting your code. This is way more...

Wow, thanks guys, today I learn! I also found a stm32duino thread after @mcauser mentioned FSMC. @OutoftheBOTS_ -- Super useful video thanks, I wasn't aware there was any kind of processing involved to get an accurate position out of the touchscreen, so there you go, something else I learned! I have...

Hey mcauser, I just got the LCD module for the BLACK_F407VE board from Aliexpress and was wondering if you had any thoughts regarding driving it from micropython (and reading the touch screen)? And the reason why I needed the sdcard to work on BLACK_F407VE is that the filesystem is about to get real...

Hey @okwatts, just got the sdcard working I think. I modified ports/stm32/sdcard.c as per @lmamakos's instructions https://forum.micropython.org/viewtopic.php?f=12&t=3086#p18286 // configure the SD card detect pin // we do this here so we can detect if the SD card is inserted before powering it on #...

Thanks Robert, it was definitely on my TODO list to try and test your editor. I am completely new to micropython development, so one of the reason I went with the kilo editor was to learn about developing modules in C. A single file (kilo.c) made this relatively painless. It'll be interesting to com...

I was looking for a small text editor that I could integrate with micropython as a C module and found kilo http://antirez.com/news/108 Someone in the comments even talks about running it on a microcontroller and gives pointers to reducing its memory footprint. For now, I've only tested this on the u...

Sorry to be resurrecting yet another old thread! I bought a few "CH340G NodeMcu Wireless WIFI Module Connector Board Replace ESP-12E ESP8266 UK" off ebay and was not able to flash them without adding --flash_mode=dout The board is labelled "HW-628 V1.1" and comes with a 4MB flash memory chip. My esp...
