What is the PRBS sequence

Hi. Could anybody tell me how to re-generate in Matlab/C the same PRBS 7 sequence used in the SIIGX_SI_Kit demos? The polynomial is X^7 + X^6 + 1. Thanks for the help!

Is your question specifically how to implement the polynomial? This is typically done using shift registers (which you can fake in C). The exponents in the polynomial indicate which bits get XOR'd with the input bit.
