LED+ and LED- pins are used to control the backlight LED. There are 8 data pins from D0-D7 and three control pins such as RS, RW, and E. Now let’s first understand the pinout diagram and commands of 16×2 Liquid Crystal display.

MPLAB XC8 LCD H CODE
MPLAB XC8 LCD H SIMULATOR
When I run the simulator in MPLAB with suitable break points the PIN_E doesn’t seem to toggle within the send_nibble function. I am using C18 compiler inside MPLAB v8.73, using a PIC18F2525 running 4MHz. I then used the PICkit 2 application to transfer the compiled hex file onto the microcontroller.ĮDIT 18-4-2015: Thanks to Brek Martin who left a comment below suggesting the 1-second delay at power-up, which apparently is required for some LCD modules.įirst off great article, I cannot get it to work though. This was the command I used: xc8 -chip=18F4620 lcd.c I compiled the program using Microchip’s XC8 compiler. Send_command_byte(0x02) // Go to start of line 1 Write the two strings to lines 1 and 2 Send_command_byte(0b00001111) // Display: display on, cursor on, blink on Send_command_byte(0b00001000) // Display: display off, cursor off, blink off

I'm putting a 1 second delay here just in case. before you can begin communicating with them, so Some LCD modules require a delay after power-up We'll wait 2ms after every command since we can't

Let's just write to the LCD and never read! TRISD = 0b00000000 // Set RD0-7 as digital outputs Void send_command_byte(unsigned char byte) Function prototypes for transmitting to LCD Select a pin to use for the flashing LED definitions in the XC8 compiler's peripheral library. dsPIC30F4011 example to avoid a clash with the equivalent NB I had to change these from the names used in my previous Select which pins the program will use for the LCD screen #pragma config OSC=INTIO67,MCLRE=OFF,WDT=OFF,LVP=OFF,BOREN=OFF Disable reset pin, watchdog timer, low voltage programming and Select clock oscillator (default frequency Fosc=1MHz -> Tcy = 4us). Written by Ted Burke - Last updated 8-10-2013 lcd.c - LCD display examplefor dsPIC18F4620 Hopefully you can work out which pins are which from the code and/or photo, as well as by referring to the more complete documentation for the dsPIC30F4011 example.
MPLAB XC8 LCD H UPDATE
I’ll have to update this later with a circuit diagram, but here’s a quick photo of the program running on a breadboard circuit.

This is the same program adapted for the PIC18F4620 microcontroller. I previously posted an LCD display example program for the dsPIC30F4011 microcontroller.
