When I wrote the lcd software I was in trouble too with port E, because I configured it like input, so they didn’t change state. I use a lcd with pic18f just like you and microchip C compiler. Both were a bit slow on the uptake. Cheers for the help Aaron. I suspect there may well be a simple ,cd but I’m yet to find it.
If you dont have it already download ldc document on the 18F it is DSB.

User Control Panel Datzsheet out. Increase your latency to initialize, IE display clear, and reset or whatever they’re called were spec’d at 1. Essentials Only Full Version. Forum Themes Elegant Mobile. I hope this helps Blusky aspforum.
Page has the table of codes for setting analog ports as digital. If anything is not just right on start-up all you will get is the boxes or dots. What are good practices when using SPI? I think the better thing is to create your own lcd datasheeh using a generic lcd datasheet.
I didnt know that but I cleared the whole thing and made port e all outputs. Had to burn thousands of machine cycles based on 20MHz clock to wait this long!
ml020l I usually get a series of faint grey dots in a grid where the characters are displayed. Why does my PIC32 run slower than expected?

That caught me out, too. 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. If you havent already found the problem. Thanks for the help I didn’t configure Port E as Digital ouputs.
Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond Forums Posts Latest Posts. I finally ran accross the answer in the microchip data sheet. I can send you code examples if you wish. I will have to look at that.
It must not only be set as output but also as digital or setting it as output is useless. I’ve tried relying on the start up delay 72 msecs to allow the LCD to self initialise. The LCD doens not operate like this dataaheet if I move the bits to a different port it works. Look at page 99 Example initializing port e.
I use the Optrex manual www. Insert wait states after display clear.

I am new at this but I had the same problem. Ddatasheet other ideas what is wrong. David, Assuming you are using a standard character lcd I would suggest you check the initialization sequence carefully. Any help will be most appreciated. You can use port e datashheet it is also an analog input.
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.
