Forum Themes Elegant Mobile. The LCD doens not operate like this but if I move the bits to a different port it works. Cheers for the help Aaron.

Look at page 99 Example initializing port e. I finally ran accross the answer in the microchip data sheet. Initializing the display this way alwayswill prevent the display from screwing up when resets occur, and is more efficient than analyzing particular PIC register bits to determine conditions of reset, and figuring out the frailties of the LCD protocol.

Insert wait states after display clear. That caught me out, too. I hope this helps Blusky aspforum.

I am new at this but I had the same problem. I think the better thing is to create your own lcd functions using a generic lcd datasheet. THEN, you can issue the command to switch over to nibble mode afterward.

What are good ratasheet when using SPI? If you dont have it already download the document on the 18F it is DSB. Increase your latency to initialize, IE display clear, and reset or whatever they’re called were spec’d at 1.

Had to burn thousands of machine cycles based on 20MHz clock to wait this long! I use a lcd with pic18f just like you and microchip C compiler. Essentials Only Full Version. If anything is not just right on start-up all you will get is the boxes or dots.

I looked at the spec sheet and it said that Port E was a digital input output port but cant get any functions to work on these pins. Thanks for the help I didn’t configure Port E as Digital ouputs. Any help will be most appreciated. It must not only be set as output but also as digital or setting it as output is useless.

Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond I usually get a series of faint grey dots in a grid where the characters are displayed.

I hope this helps Blusky. I suspect there may well be a simple explanation but I’m yet to find it.

When I wrote the lcd software Lcdd was in trouble too with port E, because I configured it like input, so they didn’t change state. You can use port e but it is also an analog input.

I can send you code examples if you wish. Haven’t received registration validation E-mail? Did you configure pins on port E as output? Why does my PIC32 run slower than expected? Both were a bit slow on the uptake.
