Try looking at the linker file and see if there is anything defined as PORTDbits, if not, see how they defined it.
HD44780 vs. KS0066
Anyone an Idea what else I could do to fix the problem? I don’t know what happened to all the other LCD guru’s. Try disconnecting both backlight wires and see if you can discern anything eata the display when you run your sketch. I will hopefully be able to get it working.
HD vs. KS — Parallax Forums
I already checked the soldering before I started programming the arduino. 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.
I wired it up as explained on the adafruit website http: Pin 16 wasn’t soldered ls0066 good, so I wired it again.
Generates various daha lengths Values given depend upon 3. Guest Super Member Total Posts: Essentials Only Full Version. I read of some Problems if the contrast isn’t adjusted properly. Hi Marine, Thanks for the code.
By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark to very light. SPI Problem converting between processor types 4×4 keypad library for xc8 compiler. I checked the other pins by using the “diode” test of my multimeter one Pin to the soldered Pin, the other to the board.
Thank you so much! Hi, Sorry I hadn’t checked this for a while. 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 hope you didn’t miss this line – it’s several lines below the photo of the ‘blocks’, just above the next photo. I’ve looked at the xlcd. It’s basically the sample code provided by microchip, modified to run with the Samsung which is HD compatible driver instead of the Hitachi HD Hope you can help me!
I also tried this code to bar a mistake of the lcd library: Also, you never commented on this from reply 3 Quote. The code you referenced is another example of this, and it’s worse than most.
Could I by any chance see the header file you used and possibly an example program using these functions? Haven’t received registration validation E-mail?
C” Line 7,8: The Hello World example. I’ve pasted it below for anyone who might be in the position I once was. Forum Themes Elegant Mobile.
I found the data sheet here: Forums Posts Latest Posts. I now found out, that the display hasn’t the HD Chip but an other which is almost the same. Look for poor joints and for bridges shorted pins. This routine configures the LCD.
Sample code for Samsung KS0066/S6A0069 LCD driver
User Control Panel Log out. This is the code I used. Follow the LCD Initialization link at http: We are back to this “The reversed backlight datta that seem to work OK still bother me as well.
Your display of two rows of blocks is an indication that the LCD is not properly initialized.
I already tried some othere libraries like the LCD4Bit but it sk0066 wor either. It’s got to be something simple that we are overlooking. Don’t wanna expend another 22 Bugs on a new LCd The LiquidCrystal library isn’t totally correct either and that could possibly be your problem, but it’s not likely. The reversed backlight connections that seem to work OK still bother me as well.
