1. Messaging between multiple Maple Mini clones

   … that talked I2C. One master and one slave. I was wanting to port that project to the maple mini, but don’t want to re-invent the wheel.

2. Need help, Why is this code running much slower than Uno?

   cat_enabler· Tue Apr 17, 2018 2:28 pm

   …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

   Unturned· Tue Oct 11, 2016 10:11 am

   Well, finally got my Maple boards. The Mini is a simplified version of the original Maple Mini (according to its descriptions) I checked and all the pinouts and microprocessors are the same. The big Maple board looks somewhat authentic. P.S. I think the “bread…

4. New SdFat library (with and without DMA)

   robca· Sun Dec 20, 2015 10:35 pm

   …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…

5. New wiki

   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…

6. No fix on u-blox neo 6m

   …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…

   madias· Tue Oct 02, 2018 9:15 pm

   …*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…

11. Porting Marlin to STM32.

    victor_pv· Mon Jul 03, 2017 8:31 pm

    …ep them all enabled all the time. Any board using a 64pin MCU should have enough, the Maple mini is definitely constrained in the number of pins, although as far as the code fits, it can be enough for a basic printer.

13. RTC Library using LSE

    …d. So it seems not that important. Interestingly the crystals that didn’t work on the Maple Mini clone are working on the DS1307 modules. Thanks for help j-zero

14. RTC Libs.

    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…
