Logging FPGAs pins on a host PC

Recommended Posts



Somebody was after a way to send the input state of pins through to a host/PC for logging, so I knocked something up from them.


It logs 11 pins as an ASCII string of ones and zeros, followed by a NL and CR, at 9600 baud on the virtual serial port. It only sends an update when the state of the input changes.



Somebody might also be able to make use of it as a debugging interface...
