    Default Testing LCD's

    Hi.
    This is my first post.
    I am quite new to pics ( and LCD's )
    I would like to be able to find out if an LCD module (HD 44780 ) that I have just bought, is working.
    I have a Velleman K8048 programmer with mpasmwin and picprog2 software.
    I have searched the internet, looking for an easy project to build on a proto board, using a 16f84 or 628, without much luck so far.
    Can anyone help me out?

    The example in the Pic Basic manual is about as easy as it gets.
    Just make sure the ADC and comparators are shut down if you pic has them..

    If you have lost your manual it can be viewed on line

    Look at the LCDOUT command.

    Amazing how that happens isn't it? I don't know about the rest of the world, but if I bought a $250 program, I don't think I'd be misplacing the manual anytime soon. Am I alone here?

    A duck at my aunt's house flew off with it
    A flash flood washed my manual away
    A team mate has it
    Another teacher borrowed it as an example to show her class an example of neatness
    I accidentally flushed it down the toilet
    I dropped it down a drain
    I dropped it in the pool while teaching my brother to swim
    I fed it to a dog which was dying of starvation
    I left it at my grandparents house
    I left it at softball
    I left it in the shower
    I left it on the school bus
    I left my manual on the UFO I was beamed up into yesterday
    I left my manual at school
    I sent it to my friend as a present
    I spilt ink all over it
    I spilt syrup all over it
    I used the paper for origami
    I was at my uncles and his robot went crazy and ripped it up
    I was hungry so ate it for a snack
    I went on a boat trip and it fell overboard
    It blew out of my hand
    It got stuck in the garbage disposal unit
    It got wet in last nights storm
    Its in dad's car
    Its under my pillow
    Mum stewed it for our tea
    Mum washed it and I forgot to take it off the line
    My bag has a hole in it and it must have fallen out
    My brother had a tantrum and ripped it up
    My brother threw it out the window.
    My cat buried it in its litter tray
    My cat died and I didn't have any paper to wrap him in, so I used my manual
    My dad put it in the safe and I've forgotten the combination
    My dad thought it was a tissue and blew his nose on it
    My dad thought it was waste paper and threw it on the fire
    My dad took it to work
    My girlfriend has it
    My homework machine broke down
    My house was invaded by bugs who ate everything paper in the house
    My mother ironed it
    My mum accidentally cooked it
    My mum accidentally used it as a nappy for my baby brother
    My mum needed it for a university assignment
    My next door neighbour's house burned down
    My sister hid it as a joke and won't tell me where it is!
    My sister in year 12 needed it for a test
    My uncle needed it for an experiment
    Porridge got spilt all over it
    The bird ate it
    The cat had kittens on it
    The dog ate it
    The dog buried it
    The English teacher has it
    The voices in my head told me to rip it up
    There was a blackout and I couldn't find my manual
    We were robbed last night and it got stolen

    Gentlemen!

    The PicBasic Manual does not list a command LCDOut. Consequently no direct LCD drawing. Now the PicBasicPro manual does have the necessary command and drawings on how to connect it.
