Nov 22, 2012 PIC16F84 + HD44780 4-bit Driver programming in C. On a project with a PIC 16F84 which I'd like to use to control a 2x16 chars LCD display (Hitachi HD44780 driver). C Library for HD44780 LCD Display Controller. This function also sets up the hd44780 interface to use 4 bit operation instead of 8 bit operation.

HD44780 LCD Driver for a PIC microcontroller with schematic and code. I will be using the PIC16F1829 to write to the LCD in 4-bit mode. HD44780 Driver Features. 4 bit 4x20 LCD with Atmega32. Seems this is a HD44780 compatible Controller. Nonetheless you can interface the Display in 4-Bit Mode.

I still enjoy working with Ardunio but I can pick up a 16 bit TI MSP-EXp430G2 for $9.95. Texas Instruments is a large company and has really embraced the DIY, maker community. Their online support and documentation is fabulous. I started getting familiar with the chip architecture for the above MSP430.

What better way to learn about the chip then to write some code. I have a few LCD display lying around and decided that this would be a good project to develop. In doing some digging out on the web I discovered that many LCD displays use the Hitachi HD44780 controller as a programmable interface. I did some searching out on the web and found a few code examples and one library that implements code for the HD44780. But most of the code was only small samples of code and really was not formatted for for real production use. Most of the code I found was incomplete, and really buggy, When I pressed the reset button several times the display when nuts and displayed corrupted characters.

Also nowhere did I fine any really good code samples that implemented the features of the HD44780 interface. So I decided to take the following library and modify it to add the features that I wanted and then provide some working code examples. So a bit thanks goes to nikosapi at Below I will publish some links to my Kiln repository, with public access so everyone can download the code. Stress Reducer Desktop Destroyer 2 there. Over the next few posts I will also discuss the coding samples I put together. I have put together a YouTube video of the code samples printing out to a 2 line 40 character display that prints 4 lines, 20 characters each.

If you have a different LCD display the library functions will still work, you may have to alter the text length that you are sending in the example code. Here is the link to the Kiln repository, Click on the 'Download Archive' to download the files to your workstation: The library was tested using the above MSP430 launchpad, but the library should work with most micro-controllers. The library and code samples were created in Texas Instruments Code Composer Studio, which is an Eclipse application with custom plug ins. But the code can be taken with run with any tool chain. Download the code so you can follow along.
