Pulse Width Bank Configuration

Configure the Frequency of Blinking

 .blinkperiod(float freq, int PSC)
			PSC =	0 for Pulse Width Configuration 1
					1 for Pulse Width Configuration 2

Configure the Brightness of the LED

 .brightness(float duty_cycle, uint8_t PWM)
			duty_cycle = 0-100%
			PWM = 	PWM0 for Pulse Width Configuration 1
					PWM1 for Pulse Width Configuration 2
