hey cam,
>>if you are using 20x4 LCD display majority uses a hitachi controller for decoding. Its like a pseudo-multi line thing. the 3rd line is actually the extension of the first and the 4th line the extension of the second one. so you can code using this.
>>great to know that my code was helpful to you
I Am offering my full support for your project.
>> the codes are identical.. didn't you notice that? the second code has been commented by me for you to better understand what i meant with some assignations and increment etc. try to have a logic picture for what you need to code. I will calm my mind for 5 minutes and then think about how to solve issues. Works every time. Try to code with calm mind and when you feel that you are not getting to anywhere just do something else like listening to music or something
TIP: have some dark chocolate with you. In times of magical coding give your brain a a treat of endorphin by having a piece of chocolate.
