Constructor & Destructor Documentation

GradationControl()

GradationControl::GradationControl	(	PCA995x *	devp,
		int	num_group,
		uint32_t	bitmap = 0x0000
	)

Create a GradationControl instance for a group

Parameters

devp	pointer to PCA9955B or PCA9957 device instance
num_group	int value to specify group number
bitmap	option. specifying channels assign into this group (bit 0 = channel 0). Assigning can be done later by "add_channel()" method
