PIC18F4550+ 122x32 graphics LCD

[agsrinivasan]

Hello all,
I am working with PIC 18F4550 USB development kit & CCS compiler. I have interfaced the LCD CMG32122 with this board. This LCD has the SED1520 controller. I have done all programming, and letters and messages displayed successfully.

I have created some sample bmp, and created the font library for that bmp file.

Is there any function available for reading the entire bmp fonts and displaying in my lcd ?

Waiting for reply.

Hi Srinivasan:

There is no way to directly read bmp files into the CCS or MPLAB files. However you can use third-party software to convert the images into data tables or arrays. These arrays of table can then be included into your code. I did a quick google; you might want to visit the following sites:
