The product detailed below complies with the specifications published by RS Components. Contrast adjustment pin- This pin is used to change the contrast settings of the LCD to make it lighter or darker so that it can be more visible.

This allows us to have a 1 millisecond pause in pkc16f690 program. C include include “lcd. We will make it count from 0 to 9 on the first line and then display the message “Hello World” on the second line.
So now you have a good rundown of what each pin of the HD is and does. The HD is a pin device.
However, if you have any other LCD and you know the pinouts and connections, you can easily use that. The software consists of several C files.

The data lines simply connect from microcontroller to LCD through jumper wires, pkc16f690 no resistors necessary. The operating voltage for LED backlights are 5V for full brightness. If we wanted to provide contrast, we could connect to a potentiometer, but for this circuit’s sake, we will simply hook it up to ground. Microcontroller Features 20 MHz Max. RS Components Statement of conformity.

Clock Enable Pin- The clock enable pin is the pin which enables the clock of the LCD to be triggered turned on so that the LCD can execute instructions that are given it. Ground- This makes the ground connection for the power of the LCD. The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering.
The product does not contain any of the restricted substances in concentrations and applications banned by the Directive, and for components, the product is capable of being worked on at the higher temperatures required by lead—free soldering The restricted substances and maximum allowed concentrations in the homogenous material are, by weight: It shouldn’t provide any issues with seeing the screen.
Ground serves as the return path for current for a device. The less commonly used read mode allows us to read characters from the LCD that are displayed on it. We will not use DB0 to DB3, so these will be left unconnected.
Write mode is when we write to the LCD so that we can display a message on it. When in instruction mode, the LCD will interpret the binary given it as instructions such as “clear the display” or “move the cursor”.
They are auxiliary pages. As stated before, the HD has 16 pins.
This code allows us to use the pause function in our main. These are what all the pins are: But there are other instructions in the delay loop so using the MPLAB stopwatch, we find that we need Timer0 to overflow at clock ticks. Either a 2 row by 16 column LCD can be used or a 20×4. We will not connect the backlights of the LCD in this circuit. We do not want to read the values from the LCD, so we don’t want it in read mode ever.
Devices with Baseline, Mid-Range or Enhanced Mid-Range architecture are available with numerous different peripheral combinations, pic1f6690 designers flexibility and choice for their applications. However, for this project we will only use pic16f6900 rows.

The HD is a device that runs on a clock. This type of circuit will form a base for all future projects involving Pic16t690. We always want it in write mode for this circuit, because we will only write characters to the LCD.
This makes for less connections and makes the circuit easier to hook up. The contrast adjustment pin, Pin 3, of the LCD connects to ground.
These 2 are the power pins of the microcontroller.
