Detailed Description

EasyGUI Graphical User Interface for embedded systems.

Function Documentation

gui_delay()

uint8_t gui_delay

(

const uint32_t

ms

)

Delay GUI in units of milliseconds.

Note

Available only when GUI_CFG_OS is enabled

Parameters

[in]

ms

Time to delay in units of milliseconds

Returns

1 on success, 0 otherwise

gui_init()

guir_t gui_init

(

void

)

Initializes GUI stack. In addition, it prepares memory for work with widgets on later usage and calls low-layer functions to initialize LCD or custom driver for LCD.

Returns

Member of guir_t enumeration

gui_process()

int32_t gui_process

(

void

)

Processes all drawing operations for GUI.

Note

When GUI_CFG_OS = 0, user has to call this function in main loop, otherwise it is processed in separated thread by GUI GUI_CFG_OS != 0

Returns

Number of jobs done in current call

gui_protect()

uint8_t gui_protect

(

const uint8_t

protect

)

Protect core from multiple thread access.

Parameters

[in]

protect

Set to 1 to protect, 0 otherwise

Returns

1 on success, 0 otherwise

gui_seteventcallback()

uint8_t gui_seteventcallback

(

gui_eventcallback_t

cb

)

Set callback for global events from GUI.

Parameters

[in]

evt_fn

Callback function

Returns

1 on success, 0 otherwise

gui_unprotect()

uint8_t gui_unprotect

(

const uint8_t

unprotect

)

Unprotect core from multiple thread access.

Parameters

[in]

unprotect

Set to 1 to unprotect, 0 otherwise

Returns

1 on success, 0 otherwise
