Types

type PCA9685

type PCA9685 struct {
	PwmChannels []PwmChannel
	// contains filtered or unexported fields
}

func Initialize

func Initialize(busNr uint8, address uint8, frequency uint8) *PCA9685

Initializes the PCA board, use i2cdetect to find the address on the bus you are using by default, the address is 0x40 the suggested frequency is 50Hz (for servos)
