Below is the Pinout and Pin Description of 16×2 LCD Module: 16×2-LCD-Module- Pins used to send Command or data to the LCD. In 4-Wire. The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD. Matrix Multimedia LCD Display LCD Display datasheet . To send a command to the LCD, data must be sent in two steps, the MSB followed by the LSB [byte.

ME and OE pins of to the ground. Q2 of is connected to Enable pin of LCD.

Backlight V CC 5V. As i already explained in 4-bit mode data is sent nibble by nibble, first we send higher nibble and then lower nibble.

For 5 x 8 dots, eight character patterns can be written, and for 5 x 10 dots, four character patterns can be written. Could you please guide me what should i do.

By continuing to use this website, you agree to their use. You are right mark P1. Here is short description. The data register stores the data to be displayed on the LCD.

Fill in your details below or click an icon to log in: You are commenting using your Facebook account. But we will summarize the common steps and put them in a single subroutine.


I am using code composer studio v6.

Of course you can make these on your own by using the command code syntax table. Specifically stm32lRB micro controller. Fill in your details below or click an icon to log in: Whereas in 8 bit mode we can send the 8-bit data directly in one stroke since we use all the 8 data lines. The right hole is positive and the datwsheet hole is for ground.

Or you may use text editor and save as. Sent data nibble by nibble with enable pin high first and then with same data with enable pin low after some delay.

Supply voltage; 5V 4. Instruction Hex Decimal 1 Function Set: The contrast adjust input is nothing but output taken from a pot. Each block has certain number of pixels. Thus when you want to read from the LCD you make the signal on this pin high and when you want to write you make the signal on this pin low. Please download the datasheet because a datasheet tells you everything there is to know the electrical parameters, command registers, pin-outs and so on.

Could you please explain this concisely. Everything is same as we have done in the initialization routine. Instead we simply put a certain ammount of delay usually to uS.


Instruction register corresponds to the register where you send commands to LCD e. For code explanation watch: Note if you use code composer studio to do this the file is already stored in datahseet current project datashee folder. Normally entry mode 0x06 is used which is No shift and auto incremement.

Notify me of kcd comments via email. A command is an instruction given to LCD to do a predefined task like initializing it, clearing 162x screen, setting the cursor position, controlling display etc. Get Our Weekly Newsletter! Commands and Instruction set.

Later in this tutorial i will explain how to use CGRAM area to make custom character and also making animations to give nice effects to your application. Arduino based GPS receiver.

Designate LCD functions, such as display format, data length, etc. Dwtasheet advise on availability and compatibility. I also tried your post from http: Log in or register to post Comment. So whichever line the error corresponds to you need to put there a semicolon.

How are you giving 5V to your LCD?
