2 Document and library rules
2.1 Predefined values and structures
2.1.1 Value: ERROR and SUCCESS
typedef enum
{
ERROR = 0,
SUCCESS = !ERROR
} ErrorStatus;
These values return the result of the functions. The value is ERROR if the function failed
and SUCCESS otherwise.
2.1.2 Structure: buttonsAndADC
struct buttonsAndADC
{
unsigned char buttonLeft;
unsigned char buttonRight;
unsigned char buttonCenter;
unsigned char (*buttonKnob)(void);
};
This global structure is defined in board_control.c, and declared in board_control.h. It
provides the status of the STEVAL-ILL015V1 buttons and knob.
Variables linked to the buttons are set to ‘1’ when the button is pressed. It remains ‘1’ until
the user resets it.
Calling buttonKnob() returns the knob current value (variable resistor connected to the
ADC).
The following commands must be executed to be able to use this structure. The functions
are declared in board_control.h (BC prefix stands for Board Control):
BC_GPIO_Configuration();
BC_EXTI_Configuration();
BC_NVIC_Configuration();
BC_ADC_Configuration();
