RUNNING ezLCD with the BASCOM Basic Compiler for AVR
----------------------------------------------------------------------------------------
This was tested on AVR STK500 development board with the default xtal is 3.68 MHz and ezLCD RX pin is connected to pin 2 of RS-232 SPARE connector on STK500 PORTD.1 thru RS-232 when using a 8515(txd pin). This is done by hooking jumper cable from portd connector PD1 to RS232 SPARE TXD ON STK500.

Cut and paste the code below to your BASCOM editor. Check this webpage for more updates:
