I finally ran accross the answer in the microchip data sheet. Haven’t received registration validation E-mail? Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond Cheers for the help Aaron. Thanks for the help I didn’t configure Port E as Digital ouputs. 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 use the Optrex manual www.

What are good practices when using SPI? Any help will be most appreciated. Forum Themes Elegant Mobile. If you havent already found the problem. You can use dtaasheet e but it is also an analog input. THEN, you can issue the command to switch over to nibble mode afterward.

David, Assuming you are using a standard character lcd I dataasheet suggest you check the initialization dwtasheet carefully. 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.

I think the better thing is to create your own lcd functions using a generic lcd datasheet.

If anything is not just right on start-up all you will get is the boxes or dots. Any help is appreciated Cheers Aaron.

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. It must not only be set as output but also as digital or setting it as output is useless.

Both were a bit slow on the uptake. I suspect there may well be a simple explanation but I’m yet to find it. Any other ideas what is wrong.

I am new at this but I had the same problem. Why does my PIC32 run slower than expected? Did you configure pins on port E as output? Look at page 99 Example initializing port e. I usually get a series of faint grey dots in a grid where the characters are displayed.

Insert wait states after display clear. Forums Posts Latest Posts. User Control Dataaheet Log out. The LCD doens not operate like l020l but if I move the bits to a different port it works. I looked at the spec sheet and it said that Port E was a digital input output port but cant get any lm0220l to work on these pins.

I hope this helps Blusky. I didnt know that but I cleared the whole thing and made port e all outputs. I can send you code examples if you wish.
