#20X4 LCD DATASHEET CODE#

Here is the code I am using and again this works on 16x2 LCD on Explorer 16 board. I know the addresses on 2 line LCD and 4line LCD are different but there should still be things visible somewhere on the display right? Any suggestions would be amazing. I tried debuggng it using Mplab and looks like it initialises it and completes the code but than I still cant see anything on the display. I tried the same code on an actual Explorer 16 board and it works but when I try it on my board, the rectangles disappear and nothing comes up on the display. When I power up the PCB I see black rectangles on 1st and 3rd line which is I believe how it is supposed to be. I have than added a variable resistor to the pin 3 o adjust the contrast which is fine. Custom LCD and Semi Custom LCD available. Available as a Serial 20x4 LCD, I2C 20x4 LCD or USB 20x4 LCD as the LK204-25 Intelligent 20x4 LCD. So it looks like I have no problem with the hardware. Industrial 20x4 Character LCD, available as Sunlight readable Transflective LCD, or negative with white LED backlight.

On the LCD datasheet I see that this is correct. I have used the schematic from Explorer 16 user guide which is below. After a long debugging process I have tried to get something on the LCD. As I couldn't find the LCD used on the Explorer 16 kit or the Microchip suggested LCDs I went for the 20x4 Winstar 2004a Alphanumeric LCD display. I have recently designed a development board (similar to Explorer 16) using the bits and pieces of Explorer 16 schematic.

Hi everyone, I have a problem regarding my design.
