Logging FPGAs pins on a host PC

Recommended Posts

Hi,

 

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

It logs 11 pins as an ASCII string of ones and zeros, followed by a NL and CR, at 9600 baud using RS232, but that can be tweaked. It only sends an update when the state of the input changes. On the development board I'm using it is to an on-board USB virtual serial port, but you could also use a USB to TTL RS232 adapter.

 

Maybe somebody may be able to make use of it as a debugging interface,..
