void ui_com_close ( uint8_t  port)

Called when communication port is closed.

void ui_com_error ( void  )

Called when a communication error occur.

void ui_com_open ( uint8_t  port)

Called when communication port is opened.

void ui_com_overflow ( void  )

Called when a overflow occur.

void ui_com_rx_start ( void  )

Called when a data is received on CDC.

void ui_com_rx_stop ( void  )

Called when all data pending are sent on port com.

void ui_com_tx_start ( void  )

Called when a data is received on port com.

void ui_com_tx_stop ( void  )

Called when all data pending are sent on CDC.

void ui_init ( void  )

Called at firmware startup.

Called at firmware startup.

Initializes the user interface.

void ui_powerdown ( void  )

Called before enter in powerdown mode.

Called before enter in powerdown mode.

Enters the user interface in power down mode.

Sets the user interface in power down mode.

void ui_process ( uint16_t  framenumber)

This process is called each 1ms It is called only if the USB interface is enabled.

Parameters
framenumberCurrent frame number

This process is called each 1ms It is called only if the USB interface is enabled.

This function processes user touch events and updates the display.

The first registered touch is used to control the cursor. Its presence is indicated with a red frame around the display. When the cursor touch moves, its movement is visualized with a trace on the display.

The second registered touch is used to control mouse buttons, and is indicated with an inner frame of which the color depends on which side the touch is for: blue for left and green for right button click. The frame is shown until the touch is released. To detect which side click it is, the position relative to the cursor touch is used, i.e., a touch to the left of the first touch will cause a left mouse click.

Parameters
framenumberCurrent USB frame number
Note
This function should be called every millisecond, e.g., for each USB frame.
void ui_wakeup ( void  )

Called when CPU exit of powerdown mode.

Called when CPU exit of powerdown mode.

Exits the user interface of power down mode.
