Initializes the LCD display.

 

 

= Syntax =

INITLCD

 

 

= Remarks =

The LCD display is initialized automatic at start up when LCD statements are used by your code.

This is done by a call to _LCD_INIT.

If you include the INITLCD statement in your code, the automatic call is disabled and the _LCD_INIT is called at the place in your code where you put the INITLCD statement. (initlcd is translated into a call to _init_lcd).

 

Why is this useful?

| In an environments with static electricity, the display can give strange output.

</div>
You can initialize the display then once in a while. When the display is initialized, the display content is cleared also.

[[File:Notice.jpg|left|Notice.jpg]]The [[CONFIG LCDPIN|CONFIG LCDPIN]] has an option to use the WR pin, and use the busy flag of the display. If you have enough pins, this is the best mode.

 

[[File:Notice.jpg|left|Notice.jpg]]The XMEGA has a built in internal oscillator that runs at a relative slow speed. If your code sets the speed to 32 MHz and you also include the $crystal=32000000 directive, you will notice a delay in the start of the code. This is caused by the fact that the delay routines are calculated with the 32 Mhz frequency, but the actual oscillator speed is 1 or 2 MHz.

There are 2 solutions possible.

- you can use $crystal=1000000 and then after you have set up the clock speed with CONFIG OSC, you can use another $CRYSTAL directive with the new speed.

- you use $INITMICRO and put the CONFIG OSC in the _INIT_MICRO code. This will ensure that the micro will run at the specified speed early as possible.
