Function Documentation

gwa_disp_get()

uint8_t gwa_disp_get

(

uint8_t

element

)

Gets the value of a particular display element.

Parameters

element

element to set. The value can be one of the following: GWA_DISP_DIGIT_0 GWA_DISP_DIGIT_1 GWA_DISP_LEDS

Returns

the value to set.

gwa_disp_get_char()

uint32_t gwa_disp_get_char

(

uint8_t

element

)

Gets the character string of a particular display element.

Parameters

element

element to set. The value can be one of the following: GWA_DISP_DIGIT_0 GWA_DISP_DIGIT_1

Returns

a 32-bit unsigned integer representing the NULL terminated string. If the value is 0xFFFFFFFF, the value of the display element was not set as an ASCII character.

gwa_disp_get_str()

int gwa_disp_get_str

(

char *

str

)

Gets a string representation of the value display.

Parameters

str	string shown on the display. The buffer should be at least 5-character long.

Returns

the number of characters written. If any of the digits was not set as an ASCII character -1 is returned.

gwa_disp_set()

void gwa_disp_set	(	uint8_t	element,
		uint8_t	val )

Sets a value for a particular display element.

Parameters

element	element to set. The value can be one of the following: GWA_DISP_DIGIT_0 GWA_DISP_DIGIT_1 GWA_DISP_LEDS
val	value to set.

gwa_disp_set_char()

void gwa_disp_set_char	(	uint8_t	element,
		char	c )

Sets a character for a particular display element.

Parameters

element	element to set. The value can be one of the following: GWA_DISP_DIGIT_0 GWA_DISP_DIGIT_1
c	character to set.

gwa_disp_set_str()

void gwa_disp_set_str

(

const char *

str

)

Sets a string for the display.

Parameters

str	string to show on the display.
