Hi all,
I am now using the uart prot on Nexy's 3 board to receive 8 bit data in
9600 baud rate from PC. My design will simply respond "#" when upper
case vowel is typed in hyperterminal and respond "N" when others are
typed. However, the result will only echo N whatever I typed. I assumed
that it was the endian problem on receiver side. May I know that If the
PC send 01010101 to the board, will the Nexy's 3 board automatically
change it to 10101010 or remains the same? Anyway, I have tried both way
but the result only echo N but not #. I have also check the clock
frequency. It is 100MHz on board and 9600 baud from PC. Therefore I made
a counter to count every 100M/9600 = 10416 clk cycle to read one bit.
Could any one help me to get out this situation? Thanks.
Tom
