MicroPython Forum (Archive)

we are building forum now, will online next week. Hi, where can we find your forum? Also I tried compiling MP from the git repo and ran into problems when it tried to link it: CC ../../lib/libc/string0.c CC ../../lib/mp-readline/readline.c CC ../../lib/netutils/netutils.c CC kendryte-standalone-sdk...

Hi, the default Maixpy firmware is run on 160MHz to get lowpower consume. K210 stand freq is 400MHz, and can be up to 600MHz without increase voltage, and able to 800MHz when increase core voltage to 1.1V. We test your test in 390MHz, it is about 1.3~1.4s Here is the video: https://youtu.be/r5fVphv...

Found an 128x32 oled skin https://www.ebay.com.au/itm/222600318809 And this ESP8266 skin https://www.ebay.com.au/itm/322629257534 It is interesting that the price of the pyboard (from the same seller) is 15.5 US$ and the Skin boards are sold for ~17 US$ and the cost of the componnents on the skin b...

2) With the uart class is there a way of dealing with true TTL level RS232. we are currently testing a system that uses the pybaord to log data from an ultrasonic sensor that ouputs the data as TTL level RS232 but we are getting garbage comming through so i assume that the data stream is inverted -...

Hi Dave, I saw your info for compiling MP for Teensy 3.5/3.6 (https://github.com/micropython/micropython/wiki/Board-Teensy-3.1-3.5-3.6) and appreciate the work you put into this. I did try compiling with a current git copy and ran into issues flashing the image to a Teensy 3.6; the Teensy loader com...

The 405 chip includes something called DMA2D which is specifically designed for blitting to shared display memories. Personally, for about the same price $61.25 US) you can get a 469 Discovery board: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/data_brief/DM00218382.pdf ...

Just a quick note, looks like there has been even more progress on badi's STM32F429 fork: https://github.com/tobbad/micropython Under the simple_lcdctrl_support branch there is working code to initialize the LCD, paint pixels, and print text-- great job badi!! Once you flash the image the LCD is ini...

Hi Dave, Thanks for the makefile and instructions. I still ended up having problems with the firmware that was generated and so I decided to try and build it in another tree I keep around for situations like this (That hasn't been modified at all). That build worked, so I suppose I did something wro...

Hi, I went to pull any updates from badi's repo and it appears that the changes have been removed (The entire integration branch) and rolled into the main MicroPython repo. That would be fine but something got broken along the way and it no longer boots with USB CDC/mass storage support. I haven't g...

Brilliant! Great work, badi. I can confirm it works as well, both for the CDC device and mass storage.
