Guest Super Member Total Posts: Note that there are several compatible LCD controllers around e. Insert images or files.

Updated for more display types. I traced the problem and cojtroller turns out the ‘busy signal’ never goes low after initialization, which I could only think it means the initialization isn’t complete.

I followed their initialization routine, and I can get the cursor to blink and everything, but then I wasn’t able to write any characters. Try disconnecting both backlight wires and see if you can discern anything on the display when you run your sketch.

Problem: Arduino & LCD with KS / SPLC

Just changed the wireing in the code: That’s pin 5 as shown bere: The new lib supports several ways of connecting with mbed:. I hope it helps you. Accept and hide this message.

The initialization routine is given on page 29 of this online manual: Essentials Only Full Version. I just can’t understand why virtually every LCD program author decides that they should deviate from the control,er sequence given in the datasheet. Below is the relevant part of my code: Fixed memoryaddress confusion in address method. I wired it up as explained on the adafruit website http: Don’t wanna expend another 22 Bugs on a new LCd I have no idea why this could be though because I’ve done everything they told me to.


Anyone an Idea what else I could do to fix the problem? There are also controllers available that are compatible and provide additional features like an increased number of segment drivers for more characters controlker internal LCD contrast voltage generators e. I already checked the soldering before I started programming the arduino. Pin 16 wasn’t soldered that good, so I wired it again.

LCD – controller : HD vs KS | Electronics Forum (Circuits, Projects and Microcontrollers)

I also tried this code to bar a mistake of the lcd library: The code you referenced is another example of this, and it’s worse than most. 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. All pins are soldered well.

I only changed the 16, 2 to 20, 4. I already tried some othere libraries like the LCD4Bit but it didn’t wor either. Hope you can help me!

HD44780 vs. KS0066

What else can I try to fix this damn problem? Follow the LCD Initialization link at http: I now found out, that controlleg display hasn’t the HD Chip but an other which is almost the same.

It almost has to ld something to do with one or more of the six data lines between the Arduino and the LCD. By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark to very light.

Here is some C code that works with C18 compiler and 18f chip. Doesn’t matter which one, I would appreciated it if you posted both.

HD44780 and compatible Text LCD controllers (4bit, I2C or SPI I/F)

The Hello World example. The reversed backlight connections that seem to work OK still bother me as well. The new lib supports several ways of connecting with mbed: Thank you very much. Lxd the good news stops there, for me anyways I’m sure you’re smarter than me because I’ve been trying to get the thing to work for the past 48 hours 14 of which was continuous, starting this morning and it doesn’t want to work.

You should have had two rows of blocks on a 20×4 display. But I am able to adjust cotroller contrast and tried already all “positions”: Forums Posts Latest Posts. Refactored to fix issue with pins that are default declared as NC.
