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? Also, you never commented on this from reply 3 Quote. I found the data sheet here: Don’t wanna expend another 22 Bugs on a new Dat I only changed the 16, 2 to 20, 4. Ka0066 display of two rows of blocks is an indication that the LCD is not properly initialized.

This could be due to a wiring problem or os0066 code problem. I’ve looked at the xlcd. I’m still thinking about it. Hi Marine, Thanks for the code.

This routine configures the LCD. There are also no bridges between pins: The “best legibility” is around 0,35V the contrast isn’t sata high, and the blocks are already visible. Try disconnecting both backlight wires and see if you can discern anything on the display when you run your sketch. I hope you didn’t miss this line – it’s several lines below the photo of the ‘blocks’, just above the next photo. For my compiler, the linker file has the following: Look for poor joints and for dzta shorted pins.


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”: Here is what I have changed the define statements too and the error I get Dat also tried this code to bar a mistake of the lcd library: That’s pin 5 as shown bere: It’s kw0066 to be something simple that we are overlooking.

The LiquidCrystal library isn’t totally correct either and that could possibly be your problem, but it’s not likely. I get an error on compile. Hi, Sorry I hadn’t checked this for a while.

Problem: Arduino & LCD with KS / SPLC

Thank you so much! The code you referenced is another example of this, and it’s worse than most. User Control Panel Log out.

Guest Super Member Total Posts: Essentials Only Full Version. Forum Themes Elegant Mobile. We are back to this “The reversed backlight connections that seem to work OK still bother me as well. All pins are soldered well.

Hope you can help me! I already tried some othere libraries like the LCD4Bit but it didn’t wor either. The reversed backlight connections that seem to work OK still bother me as well. The Hello World example. I wired it up as explained on the adafruit website http: Just changed the wireing in the code: 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.


Sample code for Samsung KS0066/S6A0069 LCD driver

Generates various delay lengths Values given depend upon 3. Try looking at the linker file and see if there is anything defined as PORTDbits, if not, see how they defined it. 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.

Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond You should have had two rows of blocks on a 20×4 display.

This is the code I used.

Sample code for Samsung KS/S6A LCD driver | Microchip

By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark daata very light. I’ve pasted it below for anyone who might be in the position I once was. Follow the LCD Initialization link at http: I will hopefully be able to get it working. I now found out, that the display hasn’t the HD Chip but an other which is almost the same.

I don’t know what happened to all the other LCD guru’s.
