Pin 16 wasn’t soldered that good, so I wired it again. I’m still thinking about it. Forums Posts Latest Posts. I wired it up as explained on the adafruit website http: Thank you so much! Haven’t received registration validation E-mail?

Problem: Arduino & LCD with KS / SPLC

It almost has to be something to do with one or more of the six data lines between the Arduino and the LCD. Here is what I have changed the define statements too and the error I get User Control Panel Log out. C” Line 7,8: Look for poor joints and for bridges shorted pins.

I checked the other pins by using the “diode” test of my multimeter one Pin to the soldered Pin, the other to the board. There are also no bridges between pins: Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond This could be due to a wiring problem or a code problem. Could I by any chance see the header file you used and possibly an example program using these functions?

Your display of two rows of blocks is an indication that the LCD is not properly initialized. By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark to very light. It’s got to be something simple that we are overlooking.

All pins are soldered well. The reversed backlight connections that seem to daata OK still bother me as well. I still suspect a bad connection between the Arduino and the LCD so now it’s time to get out the magnifying glass and check the solder connections on the LCD pins. I’m not sure what that error dqta, maybe the linker file that you use has not defined PORTDbits since you have a different compiler?

Essentials Only Full Version.

We are back to this “The reversed backlight connections that seem to work OK still bother me as well. I’ve pasted it below for anyone who rata be in the position I once was. I get an error on compile.

Guest Super Member Total Posts: I already tried some othere libraries like the LCD4Bit but it didn’t wor either. Try disconnecting both backlight wires and see if rata can discern anything on the display when you run your sketch.

I’ve looked at the xlcd. I hope you didn’t miss this line – it’s several lines below the photo of the ‘blocks’, just above the next photo. One other thing I might suggest, maybe you could use different port for the RS, RW, E, I know that you’d mask port D to make sure other than data bits nothing’s affected, but it’s good to be on the safe side.

That’s pin 5 as shown bere: The “best legibility” is around 0,35V the contrast isn’t to high, and the blocks are already visible. I already checked the soldering before I started programming the arduino. I also tried this code to bar a mistake of the lcd library: Why does my PIC32 run slower than expected? Follow the LCD Initialization link at http: Generates various delay lengths Values given depend upon 3. I read of some Problems if the contrast isn’t adjusted ks00666.

Just changed the wireing in the code:
