    I'll try the contrast in the morning, i think i got a 10K pot somewhere...

    I just wrote a simple "hello world" type LCD test program...

    I loadedit into oshonsoft's pic simulator and configured it's LCD module...
    Acording to the microcontroller view, all the data lines switch to outputs...
    However, it gets into a loop with nothing displayed in the LCD module, and tmr1 prescaler is continueously counting up by 1 each loop but over flows without a change in instructions...

    :edit after about 17000us in simulation RD0, RD1,RD5 and RD4 to high... still nothing on LCD module

    :edit after 22000us in simulation it has now started putting charecters on the LCD...
