# Micro Controller Snake

Small game based on the idea of snake. Runs on the Heltec WifiKit 8 (easily adapted to another esp8266 based device, as long as there is a screen attached).

This code is based on the source written for the 2018 Area41 Security Conference Badge.

## Howto

### Preparation

Initialise the project.

Important:

- If you pulled this repo, already done, won't be needed anymore

- If you use another IDE, either remove or replace the --ide param

> pio project init --board heltec_wifi_kit_8 --ide clion

To use CLion as an IDE, or when things wont work as expected, (re-)run this command. Sometimes the IDE gets confused by PlatformIO and needs its config to be re-initialised.

> pio project init --ide clion

### PIN_IN

This code reads some registers to get the pin state of the buttons. You will need the following fix or you will get the following error:

> undefined reference to `PIN_IN'

Search for a file called "*eagle.app.v6.*.ld".

It usually is at:

```

/home/user/.platformio/packages/framework-arduinoespressif8266/tools/sdk/ld/eagle.app.v6.common.ld

```

Then add this line to that file, just besides another PROVIDE you find at the beginning:

```

PROVIDE(PIN_IN = 0x60000318);

```

Accessing PIN_IN in your source will give you access to the register with all the pins current states.

### Having fun

To update middleware

> pio update

To compile

> pio run

To upload to the device (attached via USB)

> pio run -t upload

To start the serial monitor

> pio device monitor

## What to look into after things compile and run

- The code is deliberately defective. You can only move once in every direction. Check the setup code. Find out what the commented out code does and why it works once and why the fix fixes things.

- Try to use buttons as mentioned in the Arduino examples vs. reading from the register directly.

- Switch speed, collectable points

- Introduce persistent high scores
