Look for poor joints and for bridges shorted pins.

I now found out, that the display hasn’t the HD Chip but an other which is almost the same. I wired it up as explained on the adafruit website http: Generates various delay lengths Values given depend upon 3. The “best dta is around 0,35V the contrast isn’t to high, and the blocks are already visible. Pin 16 wasn’t soldered that good, so I wired it again.

Essentials Only Full Version. 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 checked the other pins by using the “diode” test of my multimeter one Pin to the soldered Pin, the other to the board.

HD vs. KS — Parallax Forums

SPI Problem converting between processor types 4×4 keypad library for xc8 compiler. Thank you so much! I will hopefully be able to get it working. But I am able to adjust the contrast and tried already all “positions”: Anyone vata Idea what else I kx0066 do to fix the problem?

  LEGO 9747 PDF

That’s pin 5 as shown bere: I found the data sheet here: There are also no bridges between pins: I don’t know what happened to all the other LCD guru’s. Forums Posts Latest Posts. I already checked the soldering before I started programming the arduino. Guest Super Member Total Posts: This is the code I used.

Sample code for Samsung KS0066/S6A0069 LCD driver

Here is what I have changed the define statements too and the error I get Hi Marine, Thanks for the code. All pins are soldered well. It’s basically the sample code provided by microchip, dsta to run with the Samsung which is HD compatible driver instead of the Hitachi HD This could be due to a wiring problem or a code problem.

You should have had two rows of blocks on datq 20×4 display. 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. The reversed backlight connections that seem to work OK still bother me as well. The LiquidCrystal library isn’t totally correct either and that could possibly be ks00066 problem, but it’s not likely.

This routine configures the LCD. I already tried some othere libraries like the LCD4Bit but it didn’t wor either. I’ve pasted it below for anyone who might be in the position I once was. I just can’t understand why virtually every LCD program author decides that they should deviate from the initialization sequence given in the datasheet. 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.


The Hello World example. Forum Themes Elegant Mobile. The code you referenced is another example of this, and it’s worse than most. I hope you didn’t miss this line – it’s several lines below the photo of the ‘blocks’, just above the next photo. Follow the LCD Initialization link at http: Try disconnecting both backlight wires and see if you can discern anything on the display when you run your sketch. I’ve looked at the xlcd. It’s got to be something simple that we are overlooking.

Hi, Sorry I hadn’t checked this for a while. I still suspect a bad connection between the Arduino and kx0066 LCD so now it’s time to get out the magnifying glass and check the solder connections on the LCD pins.

For my compiler, the linker file has the following: Why does my PIC32 run slower than expected? User Control Panel Log out. Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond I get an error on eata.

Just changed the wireing in the code: By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark to very light. I only changed the 16, 2 to 20, 4.
