BitWizard-Ruby

Ruby library for controlling the BitWizard boards (over both SPI and I2C, though only SPI is tested for now) Built using pi_piper, so for now it only works on the Raspberry Pi

Just run # gem install bitwizard as root to install the library.

Reading PWM values from a spi_3fets board would be something as simple as;

require 'bitwizard'

board = BitWizard::Board.detect address: 0x8a
puts "#{board.type}:"
(1..3).each do |i|
  puts "  #{board[i]}"
end

If you want to use the i2c version of the board all you would have to do is add bus: :i2c

board = BitWizard::Board.detect address: 0x8a, bus: :i2c

You can also use the bitwizardctl utility to perform simple actions without writing your own software, things like;

• Reading/Writing PWM values
• Getting/Setting stepper position/target/delay
• Spinning/Stopping motors
