This is an attempt to write an open-source customizable firmware for GeekVape Aegis Legend modbox.
This project is in very early stages of developpement and I can't really ensure that it'll be achieved one day. For now, I do not recommend uploading the firmware to any box. It may just be dangerous. For this reason, the binary is not yet available.
I'd really appreciate if someone could tell me what the pins 16 (PF.4) and 45 (PB.1) of the MCU are used for. PF.4 seems to be battery-related, and PF.1 display-related, but as long as I do not have a dead box to disassemble to look where they track to, it is still a bit mysterious.
