Arduino LCD playground | LCD 4-bit library library built into the IDE will also work using 6 Arduino Pins in 4 bit mode. Display 16×2 (KS controller, black & white, no back-light, HD code compatible). I suggest you start with the original arduino LCD tutorial, using all 8-bits in the data-bus. (For another sample code for KS/S6A, go to .. If 4-bit mode * – whether When in 4-bit interface define if the data is in the upper. In 4-bit bus mode open these pins. MPU. DB DB7. I/O. Data bus When 8-bit bus mode, used as high order bidirectional data bus. In case of

This routine configures the LCD.

If the packages were smaller, I’d contemplate sitting two 4×20 side by side, but the circuit boards and bezels on the LCD keep the actual displays from lining up close to one another. It has been tested successfully with:. I’ve pasted it below for anyone who might be in the position I once was. Quick Links Categories Recent Discussions.

The playground is a publicly-editable wiki about Arduino. I’d like to know if anyone has had success with this controller and what the trick was. Board Setup and Configuration.

Interfacing to LCDs with Samsung KS controller — Parallax Forums

It has been tested successfully with: First lets see the timing diagram for sending the data and the command signals RS,RW,ENaccordingly we write the algorithm and finally the code. Here each character is displayed in a matrix of 5×7 pixels. In fact the initialization sequence for the Hitachi works on the Samsung controller.


I’m not sure dtaa that error means, maybe the linker file that you use has not defined PORTDbits since you have a different compiler? Add to that the fact that the second controller was not responding, I know I could have had up to three pin connections wrong.

The following path should exist afterward: I’ve had good success with serial LCDs, but cannot find them in 4×40 size. Arduino on other Chips. I’ve created a googlecode project to maintain the source, at modd Forum Themes Elegant Mobile. The library ks00666 intended to be a 4-bit replacement for the original LCD tutorial code and is compatible with very little change.

Sample code for Samsung KS0066/S6A0069 LCD driver

Sources for Electronic Parts. Hi Marine, Thanks for the code. Download the complete project folder from the below link: Thank you so much! But I am still failing to get anything but garbage to print on the display.

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 For my compiler, the linker file has the following: I’ve looked at the xlcd.

As it turns out, the initializing sequence difference between the Samsumg KS and the Hitachi HD was not the issue. To change this behavior to be able to use any Arduino rata, change these lines: My Research found a datasheet for the KS and it is in there that I learned that the initialization sequence is a bit different.

Interfacing to LCDs with Samsung KS0066 controller

This pin is used to send the enable trigger to LCD. It is also faster and less resource hungry, and has more features. It is effectively redundant. LCDOUT commands can produce results, but they are random characters, but consistent in ks0066 experiment.


In your circuit 1: The pin sk0066 for the data pins are hard coded in the library. It was neillzero ‘s conversion of the code from Heather’s original Arduino LCD tutorial which required 11 Arduino pins. Compatibility This library should work with all HD -compatible devices. This library should work with all HD -compatible devices. User Control Panel Log out. Haven’t received registration validation E-mail?

Download the old library! 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.

To change this behavior to be able to use any Arduino pins, change these lines:. C” Line 7,8: Apart from alpha numeric chars it also provides the provision to display the custom characters by creating the pattern. My suspicion is that because these commands are lower in value on the LSB side of a bytethat I’m only successful with them because the MSB nibble is getting chopped off. Below schematic shows the minimum connection required for interfacing the LCD with the microcontroller.
