I have 366 bytes of EEPROM memory left on my board and I want to ideally cram 60+ sequences of 18 numbers. Each number in that sequence is a value between 0-127. Using hexadecimal I can get 40 sequences of 18 numbers, but is there a way to get even more?
The values are not always 3 digit, but they can be that high. Anyone know of any methods that could solve this problem?
Let's look at what you have to work with:
366 bytes * 8 bits / byte = 2928 bits available
If your numbers can take any value between 0 and 127 (and no compression is possible), then the absolute most efficient way to pack them is to use 7 bits per number. So:
60 sequences * 18 numbers / sequence * 7 bits / number = 7560 bits required.
Doesn't promising, does it?
