This it's a **TOY**, Please don't keep your top priority keys here.
I disclaim any responsability for anything that may happen to your TOTP keys.
## Hardware
To make your own RustyToken you'll need:
- 1 Arduino (UNO/Nano)
- 1 RTC DS3231
- 1 Screen STN LCD 16x2 without i2c interface
- 2 push buttons
- 1 220 ohms
- A lot of wire
## Software
To build the firmware for your Arduino you'll need:
- A linux machine (I don't know if this compile on another OS)
- All the rust env tools (rustc, cargo, rustup)
- The Rust's nightly version
- all the AVR env build tools (avr-gcc, avr-binutils, avr-libc, avrdude)
- Python3 to use the tool
## How to build and load the firmware
To build the firmware you execute:
```Bash
$ ./build.sh
```
And to upload it to the Arduino, connect it to the computer and execute:
```Bash
$ ./upload.sh
```
IF this step fails, edit the `upload.sh` script and change the `/dev/ttyUSB0` to the Serial port assiged to your Arduino (You can check this path with the Arduino IDE)
