Many applications don’t need this flash memory so you could use it to store some texts.

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. Examples datashewt Atmel interface to the LCD display.

So our module uses 8 parallel lines to send data to it. C1 and C2 are needed to work properly.

The header file “defines. The same example of a binary counter from the previous Unit 4. The LCD module is connected to the connector J2. Each character in the lcd[] character array will use a single byte of RAM. Atmel also includes many information on how to drive a full featured segment LCD.

A pointer to this datasheeet is then passed to the writeString function. Please make sure every call to this macro contains 8 parameters. From the same author, you can learn how to interface a graphical LCD screen: Each message can contain up to 15 characters The 16th character should always be 0. This is a complete project using the LCD Example design 3: The C functions for the latest XC8 compiler from Microchip are available here: It turned out the LML has 14 connections: The LML module has daatsheet connections that can be soldered.


My application defines an array of characters containing the String to show on the LCD. 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. Using this program on a 16F84A microcontroller has a huge disadvantage: The circuit should be powered by a 5 VDC stabilized voltage.

Now enhanced with the LCD display to show some messages on the 2-row 20 character screen. The numbering 1 starts with the right connection of the last row.

The connections are not numbered but you can find the numbering in the datasheet of the LML. Define the lcd[] array as a constant. There is no need to access 10, times every second the LCD, it would represent a waste of microcontroller’s processing time, and the chip has to perform other duties than accessing unnecessarily to the display.

Note eatasheet in order program wisely, you should write the LCD when there is new information to be represented. The used circuit is very easy. Every C compiler contains the libraries to handle all the peripherals and many more in folders.

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. The information in this datasheet applies to the LML module as well.

The datasheet will show you how to connect the LCD module. The module can display 2 lines with 20 characters each. V2 Using this program on a 16F84A microcontroller has a huge disadvantage: The capacitor C3 will filter out the high frequency noise. Of course this is only usable when your PIC firmware isn’t too large because you lose space for your program.

This HD has its own datasheet and counts no less datxsheet 59 pages! RB4 will drive the DB data pins. Note how it is necessary to compile together in the same project all the following files, in order to obtain the executables.

This function will transmit the bytes to the LCD module. We can’t afford to use 11 of them just to control an LCD module. 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.

Here you are a very good link to read more on the subject: I see a few possibilities to overcome this problem:.

Be aware that the folder is very far away from the root directory. The Vo connection, to regulate the contrast of the module, is connected to the GND fixed contrast. I found an old one and tried to make it work. You need to add a voltage regulator and some capacitors if you don’t have a stabilized voltage.

Units Chapter IV units Unit 4. It can be used to store data, even if the power is turned off.
