Screen Text Display Functions

These functions allow programmers to display text on the v5 screen

uint32_t screen_print(text_format_e_t txt_fmt, const int16_t line, const char* text, ...)

Print a formatted string to the screen on the specified line.

uint32_t screen_print_at(text_format_e_t txt_fmt, const int16_t x, const int16_t y, const char* text, ...)

Print a formatted string to the screen at the specified point.

uint32_t screen_vprintf(text_format_e_t txt_fmt, const int16_t line, const char* text, va_list args)

Print a formatted string to the screen on the specified line.

uint32_t screen_vprintf_at(text_format_e_t txt_fmt, const int16_t x, const int16_t y, const char* text, va_list args)

Print a formatted string to the screen at the specified coordinates.

Screen Touch Functions

These functions allow programmers to access information about screen touches

screen_touch_status_s_t screen_touch_status(void)

Gets the touch status of the last touch of the screen.

uint32_t screen_touch_callback(touch_event_cb_fn_t cb, last_touch_e_t event_type)

Assigns a callback function to be called when a certain touch event happens.
