# Blink

This 'Hello World' equivalent simply blinks the RGB LED. They're high intensity LEDs that will almost
burn your eyeballs if you stare at it long enough.

# Requirements

* Yosys
* Arachne-pnr
* Project IceStorm

# Usage

* ```make```

Builds ```chip.bin``` bitstream

* ```make flash```

Program the bitstream to the device.

Expected output during flashing:

```
ubuntu@ubuntu-xenial:~/projects/upduino$ sudo make flash
iceprog chip.bin
init..
cdone: high
reset..
cdone: high
