How to change port of PIC microcontroller to other port?
Connect RD0-RD3 pins with D4-D7 pins of LCD respectively and other pins with RW, EN, RS and Power pins. But you can change PORT to other PORT of PIC microcontroller also by changing the PORT name with these commands. This function initializes the LCD commands to select 4-bit mode and other configuration settings.
How to interface 16×2 LCD with PIC microcontroller?
How to Interface 16X2 LCD with PIC Microcontroller? First of all, to interface LCD with a pic microcontroller, we used GPIO pins. GPIO pins are general-purpose input-output pins. Because we send control and data signals to LCD through these I/O pins. Therefore, you should know how to use digital input-output pins of the pic microcontroller.
How many pins are connected to a microcontroller?
In 4-wire mode, only four pins are connected to the microcontroller unit like 0 to 3, whereas in 8-wire mode, 8-pins are connected to microcontroller unit like 0 to 7. Pin 16 (-ve pin of the LED): This pin is connected to GND. The features of this LCD mainly include the following. The operating voltage of this LCD is 4.7V-5.3V
Can you use different ports or pins for interfacing the LCD?
You can use different ports or pins for interfacing the LCD before going to different ports please check the data sheet whether the pins for general purpose or they are special function pins. Interfacing LCD to PIC is not different from interfacing to 8051. The basic concept and gist of the programming is almost same.
Why do I need a microcontroller for LCD?
Therefore, if you are not able to see anything on LCD after programming, the maximum changes are that you need to adjust contrast with the variable resistor. This contrast register makes adjust to the voltage applied on the VEE pin. In this tutorial, we will use two pic microcontroller compilers for programming:
How many characters can a mikroC Pro Display?
MikroC pro has a built-in library. We have used 16×2 LCD which means there are 2 rows and 16 characters in each row. So we can display a total of 32 characters at a time in two rows with 16 characters in each row. This is the main command which prints our text on LCD. It also gives the privilege to specify the position of the text.
