About

I looked into PlatformIO usage with the STM32 series after going thorugh Jan Hendrik's Otterpill workshop. This is the absolutely minimal blink exmaple.

It remains unclear to me how or if I could use a configuration that was generated with CubeMX in a PlatformIO project.
See Using STM32CubeMX with PlatformIO (archive) on how to import CubeMX configuration into your project or use stm32pio.

Usage

• Create the files platformio.ini and src/main.c from the sources above.

1. Create compressed squashfs image

Use mksquashfs to create a compressed image from a directory. Depending on how compressible the files are you could put on much more than 4.7 GB on a single disc.

mksquashfs /path/to/my/directory image.sqfs

You can use a different compression algorithm with e.g. -comp zstd or append multiple times to one archive to fill it up to almost the allowable size.

2. Reencrypt the image to wrap it in a LUKS container

Adafruit DotStar + FT232H library

Simple library to drive APA102 LED strips with an Adafruit FT232H breakout board over its SPI pins.

The packed format for the pixels is known from an exploration of the APA102 LEDs on Tim's Blog.

Example Usage

• Connect the LED strip to the first four pins: 5V, GND, D0 (CLK --> CI), D1 (MOSI --> DI)
• Follow the Adafruit guide to install adafruit-blinka and set BLINKA_FT232H=1 in your environment
