Using this program on a 16F84A microcontroller has a huge disadvantage: I datasheett a few possibilities to overcome this problem:. From the same author, you can learn how to interface a graphical LCD screen: Here you are a very good link to read more on the subject: Please make sure every call to this macro contains 8 parameters.

LM032L Datasheet

Now enhanced with the LCD display to show datqsheet messages on the 2-row 20 character screen. The LML module has 14 datashset that can be soldered. C1 and C2 are needed to work properly.

Examples of Atmel interface to the LCD display. Note that in order program wisely, you should write the LCD when there is new information to be represented. Atmel also includes many information on how to drive a full featured segment LCD.

The location of the LCD interface C libraries. The C functions for the latest XC8 compiler from Microchip are available here: The capacitor C3 will filter out the high frequency noise.

The circuit should be powered by a 5 VDC stabilized voltage. We can’t afford to use 11 of them just to control an LCD module. Use NULL 0 values when you don’t need any more characters. I see a few possibilities to overcome this problem: The header file “defines. Of course this is only usable when your PIC firmware isn’t too large because you lose space for your program. The datasheet will show you how to connect the LCD module.


You need to add a voltage regulator and some capacitors if you don’t have a stabilized voltage. The used circuit is very easy. In this 4-bit mode each byte is transmitted in two phases: RB4 will drive the DB data pins.

It turned out the LML has 14 connections: V2 Using this program on a 16F84A microcontroller has a huge disadvantage: Each character in the lcd[] character array will use a single byte of RAM.

This function will transmit the bytes to the LCD module. This HD has its own datasheet and counts no less than 59 pages! The module can display dwtasheet lines with 20 characters each. Note how it is necessary to compile together in the same lm03l all the following files, in order to obtain the executables. This is a complete project using the LCD Example design 3: The LCD module is connected to the connector J2.

The C routines available in the compiler can be found in this folder, which is a part of the Atmel Studio resources automatically installed among many more C source files to lj032l used as examples. However, if you like to experiment on using displays, there are many more LCD driver functions on the internet witch can be adapted to many Atmel AVR chips. Units Chapter IV units Unit 4. Be aware that the folder is very far away from the root directory.


The same example of a binary counter from the previous Unit 4. A pointer to this daasheet is then passed to the writeString function.

Each message can contain up to 15 characters The 16th character should always be 0. You only need two hardware pins on the microcontroller.

An LCD display with two lines, 16 characters each, is connected to the 28 and pin sockets. So our module uses 8 parallel lines to send data to it. Here you are a very good link to read more on the subject:.

The numbering 1 starts with the right connection of the last row. Over the internet you’ll find hundreds of examples to interface the an LCD to a microcontroller, different libraries for different compilers and microcontrollers and vendors, which in the end is a mesh that make it difficult to decide what to choose.

The image is not very clear but at the left of the module there are 14 soldering contacts, formed by 2 vertical rows with 7 connections each.
