Function Documentation

TM_BUTTON_t* TM_BUTTON_Init	(	GPIO_TypeDef *	GPIOx,
		uint16_t	GPIO_Pin,
		uint8_t	ButtonState,
		void(*)(TM_BUTTON_PressType_t)	ButtonHandler
	)

Initializes a new button to library.

Note

This library uses malloc() to allocate memory, so make sure you have enough heap memory

Parameters

*GPIOx	Pointer to GPIOx where button is located
GPIO_Pin	GPIO pin where button is located
ButtonState	Button state when it is pressed. 0: Button is low when pressed > 0: Button is high when pressed
*ButtonHandler

Return values

Button

creation status: 0: Button was not created > 0: Button created and saved to library, button pointer is returned

TM_BUTTON_t* TM_BUTTON_SetPressTime	(	TM_BUTTON_t *	ButtonStruct,
		uint16_t	Normal,
		uint16_t	Long
	)

Sets press timing values.

Parameters

*ButtonStruct	Pointer to TM_BUTTON_t structure for button used
Normal	Time that button must be pressed to indicate normal press. Value is in milliseconds
Normal	Time that button must be pressed to indicate long press. Value is in milliseconds

Return values

Pointer

to TM_BUTTON_t

void TM_BUTTON_Update

(

void

)

Updates buttons. This function have to be called periodically.

Note

Function will automatically call callback functions for buttons

Parameters
