Function Documentation

c1201_display_clear()

void c1201_display_clear

(

void

)

Clear display.

Clears the display by a master reset.

c1201_display_number()

void c1201_display_number

(

uint8_t

number

)

Display a number.

Displays a number by transmitting the corresponding segment pattern. The range of number must be between 0 and 99. Leading zeros are suppressed.

Parameters

number

The number to be displayed.

c1201_display_off()

void c1201_display_off

(

void

)

Turn display off.

Turns the display off by shutting down the PWM.

c1201_display_on()

void c1201_display_on

(

void

)

Turn display on.

Turns the display on by activating the PWM.

c1201_display_symbols()

void c1201_display_symbols	(	uint8_t	dis1,
		uint8_t	dis2
	)

Display symbols.

Display two code B encoded symbols on the display. The following encoding is used:

Code	0	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
Symbol	0	1	2	3	4	5	6	7	8	9	-	E	H	L	P	blank

Parameters

dis1	The row to be activated
dis2	The row to be activated

c1201_init()

void c1201_init

(

void

)

Initialize click module.

Initializes the click module by setting up the SPI module, the PWM module and the reset line. The display is turned off after initialization.

c1201_set_intensity()

void c1201_set_intensity

(

uint8_t

intensity

)

Dim display.

Dims the display by specifying the desired intensity. The intensity corresponds to the duty cycle of the PWM signal used to control the luminance.

Parameters

intensity

The per cent intensity of the luminance.

c1201_transmit()

void c1201_transmit	(	uint8_t	dis1,
		uint8_t	dis2
	)

Transmit the segment patterns.

Selects at which row the stored data is displayed.

Parameters

dis1	Segment pattern for display 1.
dis2	Segment pattern for display 2.
