Read four bytes from the eeprom, in sequence. Put each byte in
a temporary variable in your C program. Then use the make32()
function to combine the four temporary variables into one 32-bit
value. Put the result of make()32 into one element of your
Buffer_Coord[] array. Create a for() loop that will execute 200 times
and repeat the above process until you have filled the array.
See the CCS manual for a description of the make32() function.
