Buttshock - ET-312 Frankenfirmware

Project Goals

This project exists to add small bug fixes, security fixes, and features to the ET-312 Electrostimulation Device Firmware.

Requirements

To apply firmware patches you'll need

To create firmware patches you'll need

  • Some Linux box
  • packages avr-as (avr-binutils package or similar)
  • a knowledge of AVR assembler

Quick Start to create new firmware patches

Run Make. It will compile some example patches and create the patch file. It will also run the commands to do the patching, ready to upload to your box. Then put the box in bootloader upload mode (hold "Menu" and "UP" while turning on and both lights should flash). Use the utils part of the firmware repo to upload to your box.

f002 is an example which

  • changes the box xor byte to 0 instead of random
  • allows serial connections to read more memory locations
  • adds a new sub-menu "More Options" and moves serial link to that menu
  • adds a menu item "Debug Mode" to the new sub-menu
  • adds a counter in the bottom right of the LCD that just increments when debug mode is enabled
  • adds a menu item "Random3" to the new sub-menu Random3 mode turns on a favourite mode for a random time, then turns off the outputs for another random time, repeating this. A bit like Random1 but without the random MA knob and with random periods with no stimulation [- moves the reset code out of the way of the 1.5 bootloader jump]

FAQ

WHY?!

There's probably hundreds if not thousands of ET-312 boxes around the world. We'd like them to work better.
