LM016L LCD DISPLAY PDF

Pin description is shown in the table below. Its extended capacity is 80 X 8 bits, or 80 characters. The character generator ROM generates 5 x 8 dot or 5 x 10 dot character patterns from 8-bit character codes see Figure 5 and Figure 6 for more details. It can generate 5 x 8 dot character patterns and 32 5 x 10 dot character patterns. Userdefined character patterns are also available by mask-programmed ROM. As you can see in both the code maps, the character code from 0x00 to 0x07 is occupied by the CGRAM characters or the user defined characters.

We come across LCD displays everywhere around us. Computers, calculators, television sets, mobile phones, digital watches use some kind of display to display the time. An LCD is an electronic display module which uses liquid crystal to produce a visible image. Contrast adjustment; the best way is to use a variable resistor such as a potentiometer. The output of the potentiometer is connected to this pin. Rotate the potentiometer knob forward and backwards to adjust the LCD contrast. A 16X2 LCD has two registers, namely, command and data.

The register select is used to switch from one register to other. A command is an instruction given to LCD to do a predefined task. Examples like initializing it, clearing its screen, setting the cursor position, controlling display etc. Processing for commands happens in the command register. When we send data to LCD it goes to the data register and is processed there. Generating custom characters on LCD is not very hard.

CG-RAM is the main component in making custom characters. It stores the custom characters once declared in the code. CG-RAM size is 64 byte providing the option of creating eight characters at a time. Each character is eight byte in size. We can generate custom characters at these addresses. Once we generate our characters at these addresses, now we can print them on the LCD at any time by just sending simple commands to the LCD.

Character addresses and printing commands are below. In the table above you can see starting addresses for each character with their printing commands. The first character is generated at address 0x40 to 0x47 and is printed on LCD by just sending simple command 0 to the LCD.

The second character is generated at address 0x48 to 0x55 and is printed by sending 1 to LCD. How to power tge LCD? This is useful to read lcd text even in darkness. Hex adresses should end at 7f not You started at the right hex address but counted in decimal. Sign in Join. Sign in. Log into your account.

Pin No. Sends data to data pins when a high to low pulse is given; Extra voltage push is required to execute the instruction and EN enable signal is used for this purpose.
