Re: uart help....the code is not working in fpga

I have done custom modem hookups between computers, and I have gotten hardware and software to work together.

I have not worked with a uart chip, nor with the programming language used in your code.

Questions that might help:

Have you tried lower transfer speeds? Get it working at 300 baud, then work your way up to the faster speeds?

Is the signal polarity correct? I seem to remember nothing except the character U (alternating highs and lows) came through okay when polarity was inverted.

Is the receiving device set to use the same baud rate as the transmitting device?

Are you experimenting with half-duplex versus full-duplex setting?

Parity versus no-parity setting? Etc.

Is your wiring connection the right sort? A null modem cable was simplest to use with the equipment I worked with.
