# UChip

This is a library for controlling Microchip Chips.  Specifically the MCP2221 and

MCP2221A.

## Examples

See the `examples` folder for more examples, but here is an example of using

GP0 as a GPIO:

```ruby

require "uchip/mcp2221"

def hit_bell pin

  pin.value = 0

  pin.value = 1

  sleep 0.009

  pin.value = 0

end

# Find the first connected chip

chip = UChip::MCP2221.first || raise("Couldn't find the chip!")

pin = chip.pin 0

pin.output!

loop do

  hit_bell pin

  sleep 2

end

```

## Problems

Right now this library doesn't support DAC or ADC, but it should be trivial to

implement.
