This is a quick list of cool payloads that can be pushed onto some common MCU boards to turn these them into actually useful everyday hacking tools.

• STM32F1 / Bluepill
  • blackmagic probe - SWD + UART adapter - https://medium.com/@paramaggarwal/converting-an-stm32f103-board-to-a-black-magic-probe-c013cf2cc38c - also a tip on how to use native UART bootloader
  • bluepill_ch341a - CH341A-compatible device (SPI EEPROM + UART)
  • i2c-star - I2C adapter (i2c-tiny-usb clone)
  • versaloon - JTAG stuff
  • DirtyJTAG - JTAG stuff
• RP2040 / RPi Pico
  • rp2040-i2c-interface - i2c-tiny-usb interface
• pico-usb-io-board - general purpose USB to SPI/I2C/ADC/GPIO interface

# Looks for matching libraries in current project and automatically assigns to current program.
# "Link existing project libraries" doesn't seem to fully work when using bulk import, and this
# pretty much reimplements this.

# After running this script you will probably want to use FixupELFExternalSymbolsScript.java too.

Advanced Recursive Diffing™

Ever needed to diff two trees of files, while doing some preprocessing on modified files? Well - we've got a solution for you. Or rather... our long friend git has.

Turns out it's perfectly legal to just use git diff --no-index on directories outside of (any) git repository. With that, we can (ab-)use built in git diff per-path/extension preprocessing feature.
