Here you are a very good link to read more on the subject: 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 be used as examples.

PIC LML LCD module

It turned out the LML has 14 connections: Of course this is only usable when your PIC firmware isn’t too large because you lose space for your program. Note that in order program wisely, you should write the LCD when there is new information to be represented. Please make sure every call to this macro contains 8 parameters. The C functions for the latest XC8 compiler from Microchip are available here: Examples of Atmel interface to the LCD display.


Define the lcd[] array as a constant. The location of the LCD interface C libraries. Using this program on a 16F84A microcontroller has a huge disadvantage: You only need two hardware pins on the microcontroller.

So our module uses 8 parallel lines to send data to it. The information in this datasheet applies to the LML module as well. Atmel also includes many information on how to drive a full featured segment LCD.

Here you are a very good link to read more on the subject:. This is a complete project using the LCD Example design 3: An LCD display with two lines, 16 characters each, daatsheet connected to the 28 and pin sockets. Each message can contain up to 15 characters The 16th character should always be 0. However, if you like to experiment on using datashdet, there are many more LCD driver functions on the internet witch can be adapted to many Atmel AVR chips.

In this 4-bit mode each byte is transmitted in two phases: The header file “defines. It can be used to store data, even if the power is turned off.

Now enhanced with the LCD ddatasheet to show some messages on the 2-row 20 character screen. A pointer to this array is then passed to the writeString function.


You need to add a voltage regulator and some capacitors if you don’t have a stabilized voltage. The capacitor C3 will filter out the high frequency noise. This HD has its own datasheet and counts no less than 59 pages! Use NULL 0 values when you don’t need any more characters.

My application defines an array of characters containing the String to show on the LCD. Many applications don’t need this flash memory so you could use it to store some texts. The LML module has 14 connections that can be soldered.

The circuit should be powered by a 5 VDC stabilized voltage. The connections are not numbered but you can find the numbering in the datasheet of the LML.

We can’t afford to use 11 of them just to control an LCD module. Datahseet Using this program on a 16F84A microcontroller has a huge disadvantage: Note how it is necessary to compile together in the same project all the following files, in order to obtain the executables.
