changing uart stop and start bit

Altera_Forum · ‎03-16-2006

Hey guys

If I want to change the start bit to '0' instead of '1'.

And if I want to change the 2 stop bits to 'ones' instead of 'zeroes'

how can this be done?

And is it posible to open the standard uart in SOPC and changed it and save it as a new component?

Best Regards

Imagine

Hi imagine,

Why do this? If the start bit were '1' (ie. Mark), then the receiver would be unable to sense a Mark-to-Space transition, identifying the start of the word. How would the sender and receiver clocks be synchronized? Can you give more explanation?

Hey

Just wanted to use the transmitter, so don't worry about the reciever :-).

I have found another way, thanx.
