It almost has to be something to do with one or more of the six data lines between the Arduino and the LCD.

HD vs. KS — Parallax Forums

I’ve pasted it below for anyone sk0066 might be in the position I once was. All pins are soldered well. I get an error on compile. I don’t know what happened to all the other LCD guru’s. 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 ks006 on the safe side.

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? Hi, Sorry I hadn’t checked this for a while.


There are also no bridges between pins: Your display of two rows of blocks is an indication that the LCD is not properly initialized. Forum Themes Dwta Mobile.

I will hopefully be able to get it working. Look for poor joints and for bridges shorted pins. Haven’t received registration validation E-mail? Try looking at the linker file and see if there is anything defined as PORTDbits, if not, see how dta defined it.

Hi Marine, Thanks for the code. User Control Panel Log out.

This could be due to a wiring problem or a code problem. The “best legibility” is around 0,35V the contrast isn’t to high, and the blocks are already visible. Forums Posts Latest Posts. 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. 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 now found out, that the display hasn’t the HD Chip but an other which is almost the kw0066. Generates various delay lengths Values given depend upon 3. Thank you so much! Here is what I have changed the define statements too and the error I get Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond That’s pin 5 as shown bere: I read of some Problems if the contrast isn’t adjusted properly.

Don’t wanna expend another sk0066 Bugs on a new LCd We are back to this “The reversed backlight connections that dataa to work OK still bother me as well. I already tried some othere libraries like the LCD4Bit but it didn’t wor either.

For my compiler, the linker file has the following: You should have had two rows of blocks on a 20×4 display. Could I by any chance see the header file you used and possibly an example dara using these functions?

HD44780 vs. KS0066

I also tried this code to bar a mistake of the lcd library: I’m still thinking about it. The Hello World example. Follow the LCD Initialization link at http: Just changed the wireing in the code: I just can’t understand why virtually every LCD program author decides that they should deviate from the initialization sequence given in the datasheet.
