# Some firmware for a corne v3 using two nice!nanos

## Required mods

The corne v3 uses only one of the TR(R)S pins, but this firmware needs both data

pins to use a uart connection (I don't feel like doing what QMK does), you'll

need to add a bodge wire between P1.04 and the unused pin of the TRRS jack (it's

the one not part of the group of three pins in a line)

## Flashing

It's possible to create uf2 files for rust firmware by using the following `memory.x`:

```

MEMORY

{

  /* NOTE 1 K = 1 KiBi = 1024 bytes */

  FLASH : ORIGIN = 0x00026000, LENGTH = 868K

  RAM : ORIGIN = 0x20020000, LENGTH = 128K

}

```

You can then use my fork of elf2uf2-rs to convert to uf2: https://github.com/simmsb/elf2uf2-rs

`elf2uf2-rs target/thumbv7em-none-eabihf/release/left left.uf2`

Make sure the softdevice hasn't been wiped from the nice!nano (you can just reflash it if it has)
