I checked the other pins by using the “diode” test of my multimeter one Pin to the soldered Pin, the other to the board. Last commit 06 Nov by Wim Huiskamp. The LiquidCrystal library isn’t totally correct either and that could possibly be your problem, but it’s not likely.
The new lib supports several ways of connecting with mbed:. Forum Themes Elegant Mobile.
Below is the relevant part of my code: It’s got to be something simple that we are overlooking. Don’t wanna expend another 22 Bugs on a new LCd Fixed memoryaddress confusion in address method. I traced 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.
HD44780 vs. KS0066
Note that there are several compatible LCD controllers around e. See the full wiki syntax in new window. Why does my PIC32 run slower than expected? I already checked the soldering before I started programming the arduino.
The initialization routine is given on page 29 of this online manual: What else can I try to fix this damn problem? User Control Panel Log out.
I only changed the 16, 2 to 20, 4. Hope you can help me! It almost has to be something to do with one or more of the six data ks066 between the Arduino and the LCD.
The reversed backlight connections that seem to work OK still bother me as well. The Hello World example.
I read of some Problems if the contrast isn’t adjusted properly. Thank you very much. This could be due to a wiring problem or a code problem. By disabling cookies, some features of the site will not work.
Problem: Arduino & LCD with KS / SPLC
Insert images or files. There are also controllers available that are compatible and provide additional features like an increased number of segment drivers for more characters or internal LCD contrast voltage generators e. But 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.
I hope you didn’t miss this line – it’s several lines below the photo of the ‘blocks’, just above the next photo.
HD44780 and compatible Text LCD controllers (4bit, I2C or SPI I/F)
I just can’t understand why virtually every LCD program author decides that they should deviate from the initialization sequence given in the datasheet. I hope it helps you. Close Start new topic Preview of your unsaved post: We are back to this “The reversed backlight connections that seem to work OK still bother me as well. The “best legibility” is around 0,35V the contrast isn’t to high, and the blocks are already visible. Just changed the wireing in the code: Also, you never commented on this from reply 3 Quote.
Doesn’t matter which one, I would appreciated it if you posted both. Debug breakpoints automatically disabled 16F88 cannot set internal oscillator frequency beyond Here is some C code that works with C18 compiler and 18f chip.

Please post your sample code if you don’t mind, that would be most appreciated. Let me know what you need and I will post. Try disconnecting both backlight wires and see if you can discern anything on the display when you run your sketch.
