Had to burn thousands of machine cycles based on 20MHz clock to wait this long! Guest Super Member Total Posts: I use a lcd with pic18f just like you and microchip C compiler. Any help will be most appreciated. I can send you code examples if you wish.

Forums Posts Latest Posts. Aside from that, if you’re using the device in nibble mode, and properly initialize it as such, then experience a hardware reset not a power on-resetthe display will still be in 4-bit mode, and may misconstrue information sent to it by the PIC.
Forum Themes Elegant Mobile. Why does my PIC32 run slower than expected? Insert wait states after display clear. User Control Panel Log out. The LCD doens not operate like this but if I move the bits to a different port it works.

kcd That caught me out, too. I hope this helps Blusky. If anything is not just right on start-up all you will get is the boxes or dots. I think the better thing is to create your own lcd functions using a generic lcd datasheet.
Increase your latency to initialize, IE display clear, and reset or whatever they’re called were spec’d at 1. I hope this helps Blusky aspforum.
Did you configure pins on port E as output? Both were a bit slow on the uptake. I suspect there may well be a simple explanation but I’m yet to find it. Cheers for the help Aaron. Haven’t received registration validation E-mail?

Any help is appreciated Cheers Aaron. If you havent already found the problem. 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 the Optrex manual www. THEN, you can issue the command to switch over to nibble mode afterward.
Essentials Only Full Version. 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. Look at page 99 Example initializing port e.
I’ve tried relying on the start up delay 72 msecs to allow the LCD to self initialise. If you dont have it already download the document on the 18F it is DSB.
I will have to look at that. Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond You can use port e but datashee is also an analog input. Page has the table of codes for setting analog ports as digital. Any other ideas what is lcr.
Thanks for the help I didn’t configure Port E as Digital ouputs. What are good practices when using SPI? I finally ran accross the answer in the microchip data sheet. It must not only be set as output but also as digital or setting it as output is useless. David, Assuming you are using a datasheeg character lcd I would suggest you check the initialization sequence carefully. I’m pretty sure it’s a predecessor to a 16F84 with 4 bit transfer.
I usually get a series of faint grey dots in a grid where the characters are displayed. Initializing the display this way alwayswill ratasheet the display from screwing up when resets occur, and is more efficient than analyzing particular PIC register bits to determine conditions of reset, and datasgeet out the frailties of the LCD protocol.
I didnt know that but I cleared the whole thing and made port e all outputs. I am new at this but I had the same problem.
