# PouetPouet
The firmware is [Keyberon](https://github.com/TeXitoi/keyberon), a
pure rust firmware.
## Features
* 60 keys, using Cherry MX switches, only 1U keycaps;
* USB-C connector;
* 1 STM32F072 MCU, with hardware USB DFU bootloader;
* Only onboard SMD component (except for the switches).
## Inspiration
* [Keyseebee](https://github.com/TeXitoi/keyseebee) for being the «I will change it quickly and have something ready in an hour» base project (even if I ended up redoing most of the hardware design).
* [Steamvan](https://github.com/jmdaly/steamvan) for some KiCad design ideas;
* [help-14](https://github.com/help-14/mechanical-keyboard) for making a nice list of existing keyboard;
* [Masterzen](http://www.masterzen.fr/2020/05/03/designing-a-keyboard-part-1/) and many others for writing online tutorials for newbies like me.
## Usefull resources
* [Mechanical Keyboard](https://github.com/help-14/mechanical-keyboard) is a list of DIY keyboards
* [Awesome Mechanical Keyboard](https://github.com/BenRoe/awesome-mechanical-keyboard) is another [https://github.com/topics/awesome](«awesome») list

## Compiling and flashing
Install the complete toolchain and utils:
```shell
curl https://sh.rustup.rs -sSf | sh
rustup target add thumbv6m-none-eabi
rustup component add llvm-tools-preview
cargo install cargo-binutils
sudo apt-get install dfu-util
```
Compile:
```shell
cd firmware
cargo objcopy --bin pouetpouet --release -- -O binary pouetpouet.bin
```
To flash using dfu-util, first put the board in dfu mode by pressing
BOOT, pressing and releasing RESET and releasing BOOT. Then:
```shell
dfu-util -d 0483:df11 -a 0 -s 0x08000000:leave -D pouetpouet.bin
```
The fist time, if the write fail, your flash might be protected. To
unprotect:
```shell
dfu-util -d 0483:df11 -a 0 -s 0x08000000:force:unprotect -D pouetpouet.bin
```
