Hello, i do not understand your question completly. What is a blank page ?
Need you a empty screen until a button is pressed ? Then create a menu function with no content and jump to this function (on setup). When a button is pressed the function is closed and the main menu is displayed.
thanks for the prompt answer
Yes I need u an empty screen until a button is pressed ?
Then create a menu function with no content and jump to this function (on setup). When a button is pressed the function is closed and the main menu is displayed.
i am trying that with no success using the LCDML_u8g2lib example
Hey,
an example:
File: LCDML_display_menuFunction
Change the mFunc_information to this contet:
// *********************************************************************
void mFunc_information(uint8_t param)
// *********************************************************************
{
if(LCDML.FUNC_setup()) // ****** SETUP *********
{
// setup function
u8g2.setFont(_LCDML_DISP_font);
u8g2.firstPage();
do {
u8g2.drawStr( 0, (_LCDML_DISP_font_h * 1), "dummy content");
u8g2.drawStr( 0, (_LCDML_DISP_font_h * 2), "empty page");
} while( u8g2.nextPage() );
}
if(LCDML.FUNC_loop()) // ****** LOOP *********
{
// loop function, can be run in a loop when LCDML_DISP_triggerMenu(xx) is set
// the quit button works in every DISP function without any checks; it starts the loop_end function
// stay in this function until a button is pressed
// reset screensaver timer (the screensaver is not called
LCDML.SCREEN_resetTimer();
if(LCDML.BT_checkAny()) // check if any button is pressed (enter, up, down, left, right)
{
// LCDML_goToMenu stops a running menu function and goes to the menu
LCDML.FUNC_goBackToMenu();
}
}
if(LCDML.FUNC_close()) // ****** STABLE END *********
{
// you can here reset some global vars or do nothing
}
}
File: LCDML_u8g2lib
change the void setup() function to this content:
// *********************************************************************
// SETUP
// *********************************************************************
void setup()
{
u8g2.begin();
// serial init; only be needed if serial control is used
Serial.begin(9600); // start serial
Serial.println(F(_LCDML_VERSION)); // only for examples
// LCDMenuLib Setup
LCDML_setup(_LCDML_DISP_cnt);
// Enable Menu Rollover
LCDML.MENU_enRollover();
// Enable Screensaver (screensaver menu function, time to activate in ms)
LCDML.SCREEN_enable(mFunc_screensaver, 10000); // set to 10 seconds
//LCDML.SCREEN_disable();
// Some needful methods
// Jump to the function and stay in it until a button is pressed
LCDML.OTHER_jumpToFunc(mFunc_information); // the parameter is the function name
}
Now the menu calls the mFunc_information function and stay in it until a button is pressed. The Screensaver is disabled in this function.
Thanks I understand this part now and the LCDML.SCREEN_resetTimer();
Great library by the way and support also
