There are a couple of board definitions, and I'll add more every time I experiment with a new (to me) board.

• WEACT_H743
• PYBLITEV10 --> This was tested with the PYB411RE UNO The latter has been modified from the original to load the SD card, which wasn't available.

I have compiled µP for a few boards, including the nRF52840 – pca100059, working on my Nordic Dongle. The builds include my custom code.

Tested on the above and:

• Nucleo-L476RG: As usual with STM boards, this was a pleasure to code and test on this device.

The kongduino module has a few functions, mostly AES-related. You need to add one line in Makefile around line 358, to include kongduino.c in the compilation process. Included commands so far:

• crc: Calculates the CRC32 of a buffer. Original code by Michael Barr. I cut it down to just the CRC32. The idea is to have useful functions without too much overhead.
• hexdump: My favorite function to show data that may not be ASCII.
• reverse_array: does exactly what it says. Not very useful but I wrote that function when I started learning about custom C modules for µP.
• [de|en]cryptAES_[ECB|CBC]: AES encryption / decryption, ECB and CBC, of a buffer whose length is a multiple of 16. I will add padding later. For the moment, DIY

Scripts

• test_aes.py: a demonstration of the aes functions.
• test_lzw.py: a demonstration of the lzw.py library.
• lzw.py: a cut-down implementation of LZW specifically for ASCII (0-127). You can put it in lib/micropython-lib/python-stdlib so that it is included in the firmware, and compiled as lzw.mpy.
• test_sx1276.py: a script to test the sx127x.py library. The script works on any machine that has an SX1276 connected to it – you just need to set the pins properly. This is set up for a Nucleo-L476RG.
• sx127x.py: the library. There are several version floating around, and most have issues. I have fixed most of them, and added features like TRNG. It'll do nicely until I write a library in C.

• calculate_crc_table.c: In the crc.c file, there's a function to compute the CRC table. I printed it out and initialize it at compile time, to save space, and improve speed.
• ziphex.sh: a bash script to zip the .hex builds, before pushing to GitHub.

I plan to add a lightweight LoRa library for sx1276. No plans for LoRaWAN, or sx1262 for now. We'll see...
