I’m not sure what that error means, maybe the linker file that you use has not defined PORTDbits since you have a different compiler?

I read of some Problems if the contrast isn’t adjusted properly. By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark to very os0066. User Control Panel Log out.

Don’t wanna expend another 22 Bugs on a new LCd For my compiler, the linker file has the following: Generates various delay lengths Values given depend upon 3. Just changed the wireing in the code: The code you referenced is another example of this, and it’s worse than most. Anyone an Idea what else I could do to fix the problem?

But I am able to adjust the contrast and tried already all “positions”: C” Line 7,8: What else can I try to fix this damn problem? SPI Problem converting between processor types 4×4 keypad library for xc8 compiler. I hope you didn’t miss this line – it’s several lines below the photo of the ‘blocks’, just above the next photo. The LiquidCrystal library isn’t totally correct either and that could possibly be your problem, but it’s not likely. There are also no bridges between pins: 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.


It’s got to be something simple that we are overlooking.

Forum Themes Elegant Mobile. Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond This is the code I used.

HD44780 vs. KS0066

Why does my PIC32 run slower than expected? I’ve pasted it below for anyone who might be in the position I once was. Try disconnecting both backlight wires and dwta if you can discern anything on the display when you run your sketch. This routine configures the LCD. I now found out, that the display hasn’t the HD Chip but an other which is almost the same. Hope you can help me!

Essentials Only Full Version. Follow the LCD Initialization link at http: Try looking at the linker file and see if there is anything defined as PORTDbits, if not, see how they defined it. I already tried some othere libraries like the LCD4Bit but it didn’t wor either.

Sample code for Samsung KS0066/S6A0069 LCD driver

The “best legibility” is around 0,35V the contrast isn’t to high, and the blocks are already visible. I get an error on compile. It’s basically the sample code provided by microchip, modified to run ke0066 the Samsung which is HD compatible driver instead of the Hitachi HD I will hopefully be able to get it working.

Look for poor joints and for bridges shorted pins. I’ve looked at the xlcd. 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 eata the LCD pins. I also tried this code to bar a mistake of the lcd library: Guest Super Member Total Posts: The Hello World example. I just can’t understand why virtually every LCD program author decides that they should deviate from the initialization sequence given in the datasheet.


That’s pin 5 as shown bere: Could I by any chance see the header file you used and possibly an example program using these functions? I checked the other pins by ks006 the “diode” test of my multimeter one Pin to the soldered Rata, the other to the board.

Problem: Arduino & LCD with KS / SPLC

Also, you never commented on this from reply 3 Quote. All pins are soldered well. It almost has to be something to do with one or more of the six data lines between the Arduino and the LCD. Hi, Sorry I hadn’t checked this for a while. Thank you so much! I wired it up as explained on the adafruit website http: We are back to this “The reversed backlight connections that seem to work OK still bother me as well.

I’m still thinking about it.

This could be due to a wiring problem or a code problem. I don’t know what happened to all the other LCD guru’s. You should have had two rows of blocks on a 20×4 display.
