Note that there are several compatible LCD controllers around e.
I only changed the 16, 2 to 20, 4. I’m still thinking about it. What else can I try to fix this damn problem? Please, contact us at support mbed.

I also tried this code to bar a mistake of the lcd library: Doesn’t matter which one, I would appreciated it js0066 you posted both. You do not have the correct permissions contrpller perform this operation. The Hello World example. Accept and hide this message. The initialization routine is given on page 29 of this online manual: I conteoller the problem and it turns out the ‘busy signal’ never goes low after initialization, which I could only think it means the initialization isn’t complete.
Thank you very much. Haven’t received registration validation Llcd Guest Super Member Total Posts: I don’t know what happened to all the other LCD guru’s. Added new getAddress method. By using the Potentiometer, I kan vary the intensitiy of the blocks from very dark to very light. You should have had two rows of blocks on a 20×4 display.

Essentials Only Full Version. I already tried some othere libraries like the LCD4Bit but it didn’t wor either.
This is the code I used. See the full wiki syntax in new window. I found the data sheet here: Below is the relevant part of my code: There are also controllers available that are compatible and provide additional features like an increased number of segment drivers for more characters or internal Cotnroller contrast voltage generators e.

I already checked the soldering before I started programming the arduino. It almost has to be something to do with one or more of the six data lines between the Arduino and the LCD.
Let me know what you need and I will post. 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. This could be due to a wiring problem or a code problem. Last commit 29 Mar by Wim Controllfr.
Refactored to fix issue with pins that are default declared as NC. The new lib supports several ways of connecting with mbed:. Please log in to start a discussion or ckntroller a question. Your display of two rows of blocks is an indication that the LCD is not properly initialized.
