I’m pretty sure it’s a predecessor to a 16F84 with 4 bit transfer. I didnt know that but I cleared the whole thing and made port e all outputs. Any other ideas what is wrong. Essentials Only Full Version. What are good practices when using SPI?

If you dont have it already download the document on the 18F it is DSB. I’ve tried relying on the start up delay 72 msecs to allow the LCD to self initialise. Page has the table of codes for setting analog ports as digital.

Guest Super Member Total Posts: If anything is not just right on start-up all lm020 will get is the boxes or dots. Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond I can send you code examples if you wish. THEN, you can issue the command to switch over to nibble mode afterward.

I use the Optrex manual www. If you havent already found the problem. I will have to look at that. Thanks for the help I didn’t configure Port E as Digital ouputs. Increase your latency to initialize, IE display clear, and reset or whatever they’re called were spec’d at 1.

I use a lcd with pic18f just like you and microchip C compiler. Haven’t received registration validation E-mail?

Insert wait states after display clear. The LCD doens not operate like this but if I move the bits to a different port it works. Any help will be most appreciated.

Had to burn thousands of machine cycles based on 20MHz clock to wait this long! I am new at this but I had the same problem.

I suspect there may well be a simple explanation but I’m yet to find it. Aside from that, if you’re using the device ldc 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 finally ran accross the answer in the microchip data sheet. Any help is appreciated Cheers Aaron. I think the better thing is to create your own lcd functions using a generic lcd datasheet.

Cheers ld the help Aaron. User Control Panel Log out. Both were a bit slow on the uptake. 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.

It must not only be set as output but also as digital or setting it as output is useless. I looked at the ddatasheet sheet and it said that Port E was a digital input output port but cant get any functions to work on these pins.
