i tried 100 numbers and it works. then when i try 150numbers, it manage to fetch till 128. so i guess, since 1 number = 4 byte, and 256words = 512bytes, so it can fill in 128 numbers only. but i tried to increase the size, and i am using Cyclone II, it has limit for internal memory. so i guess i will use small data size to transfer.
