Graphic object API properties

4.3.1

Graphics controls:: properties

Below are some DEFINES that are useful for some of the graphic object parameters.

#define MAX_CTRL_X_PAGE 30 /* Defines the Max number of graphic objects per page */

#define MAX_NAME_LENGTH 22 /* Defines the Max name length for graphic objects */

#define MAX_LABEL_LENGTH 46 /* Defines the Max length for Label (Label objects) */

#define MAX_BUTTON_LABEL_LENGTH 16 /*Defines the Max Label length of Button objects*/

#define MAX_CHECKBOX_LABEL_LENGTH 25 /* Defines the Max Label length for Checkbox */

#define MAX_RADIO_OPTION_LABEL_LENGTH 12 /* Defines the Max Label length of

RadioButton */

#define MAX_RADIO_OPTIONS 3 /* Defines the Max options number of RadioButton group */

#define MAX_COMBO_OPTIONS 10 /* Defines the Max values number of ComboBox objects */

#define MAX_COMBO_LABEL_LENGTH 16 /* Defines the Max Label length for the ComboBox */

#define MAX_SWITCH_LABEL_LENGTH 12 /* Defines the Max Label length for the Switch */

#define MAX_SLIDE_LABEL_LENGTH 16 /* Defines the Max Label length for the Slidebar */

#define MAX_HIST_LABEL_LENGTH 7

/* Defines the Max Label length for the Histogram */

#define MAX_GRAPH_LABEL_LENGTH 7 /* Defines the Max Label length for the GraphChart */

#define MAX_HIST_POINTS 50 /* Defines the Max number of points for the Histogram */

#define MAX_GRAPH_POINTS 100 /* Defines the Max number of points for the GraphChart */

4.3.2

Graphic Object:: PagesList array

The GraphicObject.h library file exports the following public property:

extern GL_Page_TypeDef* PagesList[];

PagesList contains the array of page pointers created statically by the application. This

object has been left as public for utility means.

4.3.3

LCD:: pLcdParam API properties

LcdHal.c exports the following public structure variable:

LCD_HW_Parameters_TypeDef * pLcdParam; /* LCD Hardware Parameters Structure */

pLcdParam hardware properties allow the final application to set the hardware

communication parameter (Bus GPIO port, GPIO pins).

●

LCD_Ctrl_Port_NCS is the GPIO port that contains the GPIO pin which the LCD

control pin is connected to

●

LCD_Gpio_Data_Port is the GPIO port dedicated to data transfer
