This is a driver to control the SD20 20 Channel I2C to Servo Driver Chip from www.robot-electronics.co.uk (http://www.robot-electronics.co.uk/htm/sd20tech.htm). This driver will allow a servo channel to be started up, stopped and the duty cycle altered in standard mode. No attempt to include the extended mode is included.
