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.

This is just a dump of some interesting undocumented features of webOS (3.8 specifically, on early 2018 4k LG TV) and other development-related tips.

Homebrew app ideas

• OpenVPN frontend (OpenVPN itself is easily buildable and runs on webOS TVs: https://discord.com/channels/407937994037919756/835489130967859251/906943542457401395)
• App autostart manager - dynamically update arbitrary app config and register it as input (see Registering an app as an input)
• webos-vncserver frontend with autostart option
• Package hyperiond into Piccap directly
• Quick Screenshot (expose HTTP port that just returns PNG of current screen contents)
• Custom IR remote codes editor/updater/blaster
