How would I code a RS232 communications between NIOS and a computer?I would like to have a preable of the character '%' and end the message with '\r\n' How can i go about this?
yes. the printf is pretty striaghtfoward, I just cant figure out how to use the scanf to recieve communications?Should I do this polling round-robin, or interrupt based receive? Do i check the register to see if there is a message? Is there a software buffer for scanf?
