I’m still daa about it. I already tried some othere libraries like the LCD4Bit but it didn’t wor either. Generates various delay lengths Values given depend upon 3. Why does my PIC32 run slower than expected? Your display of two rows of blocks is an indication that the LCD is not properly initialized.

The “best legibility” is around 0,35V the contrast isn’t to high, and the blocks are already visible. Don’t wanna expend another 22 Bugs on a new LCd Haven’t received registration validation E-mail?

All pins are soldered well. I checked the other pins by using the “diode” test of my multimeter one Pin to the soldered Pin, the other to the kd0066. I now found out, that the display hasn’t the HD Chip but an other which is almost the same. I found the data sheet here: This is the code I used. It almost has to be something to do with one or more of the six data lines between the Arduino and the LCD.

I’m not sure what that error means, maybe the linker file that you use has not defined PORTDbits since you ,s0066 a different compiler? Hope you daga help me! For my compiler, the linker file has the following: I don’t know what happened to all the other LCD guru’s. That’s pin 5 as shown bere: Look for poor joints and for bridges shorted pins. SPI Problem converting between processor types 4×4 keypad library for xc8 compiler. I wired it up as explained on the adafruit website http: Try disconnecting both backlight wires and see if you can discern anything on the display when you run your sketch.


Sample code for Samsung KS/S6A LCD driver | Microchip

This could be due to a wiring problem or a code problem. I’ve pasted it below for anyone who might be in the position I once was. 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.

Forum Themes Elegant Mobile. This routine configures the LCD. Could I by any chance see the header file you used and possibly an example program using these functions?

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 I already checked the soldering before I started programming the arduino. Also, you never commented on this from reply 3 Quote. I will hopefully be able to get it working. There are also no bridges between pins: By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark to very light.

HD44780 vs. KS0066

Hi, Sorry I dat checked this for a while. Hi Marine, Thanks for the code. 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.


Here is what I have changed the define statements too and the error I get C” Line 7,8: Essentials Only Full Version. We are back to this “The reversed backlight connections that seem to work OK still bother me as well.

I only changed the 16, 2 to 20, 4. I’ve looked at the xlcd. I hope you ms0066 miss this line – it’s several lines kx0066 the photo of the ‘blocks’, just above the next photo. Thank you so much!

What else can I try to fix this damn problem? Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond The LiquidCrystal library isn’t totally correct either and that could possibly be your problem, but it’s not likely.

Problem: Arduino & LCD with KS / SPLC

Try looking at the linker file and see if there is anything defined as PORTDbits, if not, see how they defined it. User Control Panel Log out. I get an error on compile. Guest Super Member Total Posts: I just can’t understand why virtually every LCD program author decides that they should deviate from the initialization sequence given in the datasheet.
