In most electronic systems, it is necessary to provide information in the visual form for a convenient user interface. The most commonly used displays in electronic systems are LED, LCD and TFT. Amongst these, an LCD display is the most cost-effective solution as it can display alphanumeric characters along with special user-defined symbols. It also contains an integrated controller which frees up the main microprocessor from the task of refreshing the display and improves overall system throughput. But at the same time it requires a large number of pins for interfacing with the system, which consume a lot of microcontroller’s ports.

The presented serial LCD module can convert any 16×2 alphanumeric LCD display to a serial LCD which communicates with the main controller using serial communication technique. The brightness of LCD backlight can also be controlled. If the text exceeds 16 characters, the remaining text automatically accommodates in the second line. The serial LCD module communicates on 9600 standard baud rate, which is compatible with all microcontrollers. Fig. 1 shows the author’s prototype of the serial LCD module.

Fig. 2 shows the circuit of the serial LCD module connected to Arduino Uno (Board1) using only one wire. Microcontroller ATmega8 (IC1) works with an 8MHz internal oscillator. It uses no-xtal bootloader which provides Arduino compatibility without 16MHz external crystal. Using 8MHz internal oscillator reduces hardware and improves power efficiency. IC1 uses its serial port to communicate with the main controller (Arduino Uno in this case). It acts as a bridge between the main controller and the LCD.

ATmega8 can be replaced by ATmega168/328 without changing the code, but the bootloader will need to be changed. Table I indicates the connections between IC1 and LCD1. The supply to the module is provided by the Arduino Uno itself as shown in Fig. 2.

The software for the serial LCD module is written in Arduino programming language. Follow the steps below to burn the bootloader and the firmware in IC1:

5. Remove ATmega8 chip from the Uno board and place back the original microcontroller. Put the programmed ATmega8 chip in the provided PCB and your serial LCD module is ready to use. If you wish to use ATmega168/328, you must choose proper bootloader and board before uploading. Sketch is compatible with all these microcontrollers.

You can use serial LCD library if you want to drive the serial LCD module using Arduino Uno. For that, connect the board with the module as shown in Fig. 2 and copy the library (serialLCD) to the libraries folder of Arduino IDE.

A single-side PCB for serial LCD module is shown in Fig. 3 and its component layout in Fig. 4. Assemble the circuit on the recommended PCB to minimise any assembly errors. Use IC base for ATmega8.

To test the circuit for proper functioning, verify correct 5V supply at TP1 with respect to TP0. The serial data to the LCD module can be seen at TP2 using an oscilloscope.

This is the latest evolution of our serial LCD. Included on a single board is a 16x2 LCD and an embedded circuit based around a PIC 16F88 and others. The Serial LCD is a simple and cost effective solution for interfacing to Liquid Crystal Displays (LCDs) based on HD44780 controller. The module takes incoming 9600 bps TTL level signals and display those characters on the LCD screen. Only three wires +5V, GND and Signal are needed to interface to the LCD.

Bought this from Robotshop retailer. Worked right away like a charm. I even changed splash screen to display my software version. However at some point it stopped displaying text, then backlight started spontaneously switching off several seconds after powering on. I connected LCD to different device and started experimenting just sending one command at a time.

My only complaint with this product is the difficulty in mounting. Finally had to drill out the holes to accept 4-40 standoffs. The Eagle files don"t include the complete board so making a screw hole template from the PCB is impossible. Otherwise works fine with my stand alone Atmega 328P using the SerLCD.h and SoftwareSerial.h libraries.

Does anybody know how to do a hard reset on this LCD? While I was uploading my code, I left it plugged into TX, and it doesn"t work anymore. I"m realizing that it probably got spammed with commands and the configuration got messed up. Does anybody know how to reset to factory defaults?

I have the same question. I now have the 3.3v serial enabled LCD (with backpack) and want to use this one for future usage. VDD of 5V can be supplied, but will the TTL work when its getting 3.3V signals from the TX from Netduino?

Is it just me, or are the solder holes for VDD, GND, and TX near the JST connector too small to accept standard pin headers? Perhaps I just need to use a little more force? I see that one of the pictures of this module shows what appear to be standard headers installed in that location, so I am confused..

I"ve put together some python code for sending serial data to these LCD screens. In particular, the code pulls my twitter status and writes it to the LCD. To work with the extra characters, I wrote functions to page the text (vertical scroll) or scroll the text (horizontal scroll). Details are available here: http://dawes.wordpress.com/2009/12/23/twitter-to-lcd/

Is it possible to wire this up in parrellel rather than use the serial function? I ran into a snag and am unable to use the serial function of this lcd? I see the pinouts on the schematic but when wired it doesn"t seem to work.

I"ve created a new splash screen for the Serial LCD, now I want to save it to the Serial LCD memory. So, exactly how do I write a "control-j" to the Serial LCD. I"ve put in the required line to transmit special character 124, but I can figure out how to format the "control-j" line of code. I"ve Googled this for about an hour and can"t find an explanation or sample code anywhere. Here"s my code...void setup() {

I"m not sure if you"re referring to comments on the website, or on your LCD screen. You can contact techsupport@ and they"ll be able to assist you further.

I have used a Labview program for this LCD. When i send character "a", the display is "0". Does anyone having a same problem. How should I troubleshoot this problem.Tq

Why do I get power out of the VDD port with only RX and GND hooked up? I have a 5V rail that I use to power everything on my board - and when I added this SerLCD I now have a bridge between the arduino power and my 5v line ... which I dont want. Can I add a diode to the VDD to stop reverse voltage from powering my board?

Quick suggestion... It"d be very helpful for some people if you guys added a note in the description pointing people to the correct 3-pin JST jumper wire to be used with these serial LCDs. Two reasons... it"s not clear that the jumper is not included, and you have 3-pin jumpers in your catalog which don"t work with this serial LCD.

I have ported LiquidCrystal library for use with the serial LCD you can look at my code here. Still working on finishing all the documentation. But putting up for now hopefully someone will find it usefull.

I"m also having the same problem after accidentally sending the control character "|" followed by "\", "-", "/" to the LCD as I was trying to animate a rotating bar to indicate a busy status.

Having ordered this exact LCD myself, I can say that aside from the issue mentioned in my other comment, it looks exactly like the picture. No bulky backpack module, everything is on a single board. Pretty sleek, really.

Edit: Got mine fixed. If you checked the soldering on all the terminals, check them again. I also sometimes was getting strings of garbage if I wriggled the terminals on the LCD (I suspect because I was getting a partial connection on the bad terminal). Resoldered and it is working fine now.

Wait, so I get the 3 pins for power and control, but whats with all the other pins on the sides? Can it be used to control another LCD besides the one built in?

The other pins are used if you want to control the LCD without using the serial standard. There"s some tutorials on how to do that with the arduino below. You have more control over what you can do with it, but it takes up more pins on the arduino. If you want to wire it up this way, don"t spend the money on the serial interface, they have cheaper LCD"s that allow you to do it this way, without the serial.
