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.

Hi Marine, Thanks for the code. It has been tested successfully with:. Here each character is displayed in a matrix of 5×7 pixels.

Interfacing to LCDs with Samsung KS0066 controller

The constructor now requires to know if your display is 1 or 2 lines. What helped was knowing that I had partial success and that getting control commands to work meant I was either sending partial commands or RS was not getting to the LCD.

My Research found a datasheet for the KS and it is in there that I learned that the initialization sequence is a bit different. See this forum post.

Interfacing to LCDs with Samsung KS controller — Parallax Forums

Retrieved from ” https: Debug breakpoints automatically disabled Future of PIC32 16F88 cannot set internal oscillator frequency beyond Sign In or Register to comment. It is effectively redundant. Once you know the working of lcd, you can directly use the ExploreEmbedded libraries to play around with move LCD.


This LCD4bit library dates from when the official library only worked in 8 bit mode.

Sources for Electronic Parts. 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? I’ve successfully gotten 4blt Stamp to communicate with a similar 4×40 LCD that uses the more common Hitachi HD controller, but the same code does not apply. A speed tuned version with assembler: I get an error on compile. Forum Themes Elegant Mobile.

How to use it The library is intended to be a 4-bit replacement for the original LCD tutorial mide and is compatible with very little change. Determining the correct pinouts was another challenge as they were not stated as correct on the company’s website. You can change these but it is necessary to use contiguous, ascending Arduino pins for the library to function correctly.

Generally speaking, LCDs with fewer than 80 characters have the data pins starting at pin 1 and the LCDs with less than 80 characters have the power and ground connections starting at pin 1. See this forum post for more troubleshooting. Ask for help on on the forum, on this thread. Related Hardware and Initiatives. Here’s what you must do after the setup described in the original tutorial: Arduino on other Chips.

Specifically, note that you should delete the library’s.

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 I’d like to know if anyone has had success with this controller and what the trick was.


This frees another arduino pin for you. For more info pleae look at this Forum Post. Could I by any chance see the header file you used and possibly an example program using these functions?

Sample code for Samsung KS/S6A LCD driver | Microchip

I also added a couple of functions to stimulate ideas, but you might want to delete them from your copy of the library to save program space. What are good practices when using SPI? For that you need to include the lcd. Scope of this tutorial is to show how to display the alpha numeric chars on LCD, Generating and displaying the custom chars will be discussed in subsequent tutorials. I’ve created a googlecode project to maintain the source, at https: Apart from alpha numeric chars it also provides the provision to display the custom characters by creating the pattern.

Sample code for Samsung KS0066/S6A0069 LCD driver

Refer this link for more info on LCD libraries. It was neillzero ‘s conversion of the code from Heather’s original Arduino LCD tutorial which required 11 Arduino pins. The below configuration is as per the above schematic. It supports all the ascii chars and is basically used for displaying the alpha numeric characters. Generates various delay lengths Values given depend upon 3.

Why does my PIC32 run slower than expected? For a basic explanation of how libraries work in Arduino read the library page. Haven’t received registration validation E-mail?
