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