  1. Microsoft spyware removal

    …risk for any organization that does use them. I guess Microsoft already know I have a Maple R3 connected to my machine.
  2. Need help, Why is this code running much slower than Uno?

    cat_enabler

    …eed. When driving Neopixels, the exact same animation code will run half as fast on a Maple Mini as on Uno. Will keep you posted if I find a solution.
  3. Need some guide for learning STM32s

    ag123

    after succeeding with the ‘maple IDE’ from leaflabs, i’ve actually gone on to try GNU ARM Eclipse http://gnuarmeclipse.github.io/ this would take 1 off the ‘arduino’ track towards the more ‘hard core’ STM32-Library track http://www.emcu.it/STM32/STM32VLDiscove…
  4. Netduino 2 Plus

    RogerClark

    … how you managed to upload via DFU, don’t you need a bootloader ?? I wasnt aware of a maple bootloader for F4. The F1 bootloader almost certainly won’t work on F4 as the setup and GPIO control etc are different. But I’m sure it could be ported. At the moment, …
  5. New SdFat library (with and without DMA)

    robca

    …both using the Arduino SD library and the newer SDFat one I can’t make it work on the Maple Mini. According to viewtopic.php?f=28&t=37&start=10#p723 I connected MOSI to pin4, MISO to 5, SCK to 6. I tried both 7 and 10 as CS, with no difference. I’m usi…

    BTW. I’ve updated the Baite Maple mini page http://wiki.stm32duino.com/index.php?ti … Maple_Mini I’m hoping that this format of page will be easy for people with no STM32 experience to understand and will get them up and running as quickly as possible I know I…

    …iving this post. I actually could not resolve the issue. Even changed the LDO for two maple mini clones with no results, but never tried removing the breadboard from the equation. I’ll give it a try today so we can have a larger sample of results. … There is n…
  8. Nucleo-L476RG Audio Library support

    …*very* private opinion: I always use the ST-Link clone for uploading (only exception: Maple mini clone). I got so many troubles in the past (especially on my Macbook Pro 13′ 2009). ST-Link always works for me ,no matter which board (F1 to F4) or OS. I have too…

    SPI OLED SSD1306 screens work out of the box with Maple Mini clone & Black F407VET6 for me, the former on Roger’s core, the later on STM32GENERIC. This is using the stock Adafruit & SSD1306 libraries. Repo here with code that works -> https://github…
