Thank's for info. I have updated the driver.Damien wrote:DMA transfers are now supported by the SPI bus, so you should no longer need to disable interrupts while doing the spi.send call.

Re: Ported to esp8266!?
I think there is no need for reverse engeneering. Schema, datasheet, FW, SDK... everything is available: https://nurdspace.nl/ESP8266
Flashing MicroPython into these modules shouldn't be hard. If anyone already tried it, how-to would be appreciated

I used it in Python without any library import it works. what can be the issue and solution?
Code: Select all
generator.next()

Re: Driver for WS2812 RGB LEDs (NeoPixels, ...)
I have played with 4 meters of NeoPixels Strip which has 240 RGB LEDs in total.
Driver works fine. I just released v1.1 with some speed optimizations. Should work for much more RGB LEDs

Re: Re-import module?
Hi stijn, I have some suggestions for you: 1) Use static source code checker like flake8 . Modern source code editors usually has plugins/extensions to integrate them and check you code on save. 2) Use pyboard.py to run and re-run your scripts on pyboard. 3) Use REPL to live debug/change your code r...

Re: Use FadeCandy with an USB hub connector
I would like to talk to a fadecandy board from my upython. The object being to send images to my Adafruit Neopixel 8x8. It seems like connecting the upython and fadecandy through a USB hub would be a simple way. Is this possible? Do I need a PyUSB library? Is there one? thanks Tom I think much simp...

Driver for AdaFruit 8x8 LED Matrix (+ Game of Life)
Hi, I made driver for AdaFruit 8x8 LED Matrix displays with HT16K33 backpack connected to I2C. Driver is here: https://github.com/JanBednarik/micropython-matrix8x8 In examples if implementation of Conway's Game of Life (maybe first ever on MicroPython :-) ) which looks pretty cool on 8x8 LED display...

Driver for WS2812 RGB LEDs (NeoPixels, ...)
Hi, I made driver for WS2812 (and compatible) RGB LEDs. Those are popular RGB LEDs used for example in AdaFruit NeoPixels.
