You need to help yourself by telling us more important information.
1) Which GLCD are you using ?
2) Which PIC are you using?
3) Have you got a simple '1HZ flashing LED' program 'up and running?
4) Have you got the GLCD to display data like 'Hello World' ?
5) Have you got pixels to turn on/off at your command?
An image of 128 x 64 is 8192 bits or 8Kbytes of data so you have at least 5 options of getting the data to the display.
a) choose a PIC with at least 8KB of EEPROM
b) choose a PIC with at least 8KB of FLASH(pgm mem)+ pgm code space
c) choose a PIC with at least 8KB of RAM
d) choose an external EEPROM,store image there,xfer to GLCD.
e) load image through serial port and into the GLCD.
option 'e' can be done with any virtually 19 pin PIC.
software(code) is dependent on what hardware you choose.
please report back and we can guide you.

1. I got the code from following website link
http://www.sonsivri.to/forum/index.php?topic=21746.0
2. all functions gives output fine but the function for displaying Image draws the partial image repeatedly every 8 lines if the image size is 128x64
3. if the image is in size 64x32 or lesser the image is ok
4. the function for displaying image at different x,y coordinate points also give image 64x32 or lesser only
5. I am using pic16f877a with 4MHz
6. i am using 128x64 lcd
i am able to display text,line,circle, box 3d box etc but unable to display image properly
please see the program given in above link and suggest me the solution thanks and regards |
