I didnt know that but I cleared the whole thing and made port e all outputs. Did you l,020l pins on port E as output?

If you havent already found the problem. The LCD doens not operate like this but if I move the bits to a different port it works. Cheers for the help Aaron. 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.

lm020p 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. Why does my PIC32 run slower than expected?

I use a lcd with pic18f just like you and microchip C compiler. I finally ran accross the answer in the microchip data sheet.

Look at page 99 Example initializing port e. David, Assuming you are using a standard character lcd I would suggest you check the initialization sequence carefully. I think the better thing is to create your own lcd functions using a generic lcd datasheet.

Insert wait states after display clear. I suspect there may well be a simple explanation but I’m yet to find it. I can send you code examples if you wish. 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.

I use the Optrex manual www. If you dont have it already download the document on the 18F it is DSB. I hope this helps Blusky. You can use port e but it is also an analog input. Both were a bit slow on the uptake.

Essentials Only Full Version. Any other ideas what is wrong.

Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond Guest Ocd Member Total Posts: User Control Panel Log out. I hope this helps Blusky aspforum. Any help is appreciated Cheers Aaron. If anything is not just right on start-up all you will get is the adtasheet or dots.

Page has the table of codes for setting analog ports as digital. I will have to look at that. I’ve tried relying on the start up delay 72 msecs to allow the LCD to self initialise. Forums Posts Latest Posts.

Increase your latency to initialize, IE display clear, and reset or whatever they’re called were spec’d at 1. Any help will ocd most appreciated. Haven’t received registration validation E-mail? 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.

I am new at this but I had the same problem. What are good practices when using SPI? It must not only be set as output but also as digital or setting it as output is useless. I usually get a series of faint ocd dots pcd a grid where the characters are displayed. Forum Themes Elegant Mobile.

THEN, you can issue the command to switch over to nibble mode afterward. Thanks for the help I didn’t configure Port E as Digital ouputs. I’m pretty sure it’s a predecessor to a 16F84 with 4 bit transfer.
