Detailed Description

The panel has 8 LEDs named LED1 to LED8. LED-EN should be connected with a jumper to enable LEDs, so PORTC is connected to the LEDs of the panel. LEDs are emitting light if the port value is low. PORTC0 - LED1 PORTC1 - LED2 PORTC2 - LED3 PORTC3 - LED4 PORTC4 - LED5 PORTC5 - LED6 PORTC6 - LED7 PORTC7 - LED8

Function Documentation

clear()

void led::clear

(

uint8_t

pin

)

Turns off the LED.

Parameters

pin	Pin of the LED

initialize()

void led::initialize

(

)

Initializes PORTC to output and turns off all LEDs.

read() [1/2]

uint8_t led::read

(

)

Reads all LED statues. Highest bit is LED1, lowest bit is LED8. Bit value is 1 if the LED is on, 0 if it is off.

Returns

LED statues

read() [2/2]

uint8_t led::read

(

uint8_t

pin

)

Reads the selected LED status.

Parameters

pin	Pin of the LED

Returns

1 if the LED is on, 0 if it is off

set()

void led::set

(

uint8_t

pin

)

Turns on the LED.

Parameters

pin	Pin of the LED

write() [1/2]

void led::write	(	uint8_t	pin,
		uint8_t	value )

Writes a LED status.

Parameters

pin	Pin of the LED
value	1 if the LED is on, 0 if it is off

write() [2/2]

void led::write

(

uint8_t

value

)

Writes all LED statuses. Highest bit is LED1, lowest bit is LED8. Bit value is 1 if the LED is on, 0 if it is off.

Parameters

value

bitmap of LEDs
