I have been trying to drive a 5x7 dotmatrix display using SPI. I need five bytes per character, so all that data has to be stored in code memory. This means for 26 alphabets I need to store 26x5=130 bytes in memory. When i try to make an array it points out an error in saying DATA SEGMENT TOO LARGE. We know that code memory is about 64k then why does it point out error. And how to solve this problem . Waqaas
