Thanks for explaining all that in detail. we have not enough memory to create buffer for either whole text as its limit is 2000 chars in eeprom or the bitmap of chars. but i can have two buffers of 90x7 bits each. this will need double buffering. is this possible to handle in this way? also double buffering will also need the function like memcpy() (as i used in vga programming). is there any technique to do so? or we have to copy whole array into actual one.

Thanks,
