Function Documentation

Button_Init()

void Button_Init

(

)

Initializes the virtual buttons using the FT6336U touch controller.

Note

The Core2ForAWS_Init() calls this function when the hardware feature is enabled.

Button_Attach()

Button_t * Button_Attach	(	uint16_t	x,
		uint16_t	y,
		uint16_t	w,
		uint16_t	h
	)

Create a virtual button based on locations and size of the button area. The Core2 for AWS IoT EduKit has 3 buttons on the face of the device that these virtual buttons are mapped to.

Parameters

[in]	x	Virtual button touch starting point in the X-coordinate plane.
[in]	y	Virtual button touch starting point in the Y-coordinate plane.
[in]	w	Virtual button touched width from the starting point in the X-coordinate plane.
[in]	h	Virtual button touched height from the starting point in the Y-coordinate plane.

Returns

An instance of the virtual button struct.
