It sems that i made it work. With the tools posted in the link i cannot write the PIC firmware, so what i did is: With the tool i re-programmed the fpga bin selecting the logic_sniffer_3.07-Demon-Core.bit, then with a PicKit2 programmer i programmed the PIC with the file OLSv1.04-firmware-v2.3.hex (the file OLSv1.firmware.v3.0.hex doesn't work, the ide of pickit2 it say that there's no configuration settings).
Then i selected the speed 921600 for the COM and when i press capture i can see something. To test if it works i made a simple sketch with arduino to just turn on and off a led:
Now if i start the capture i can see just one line that go up or down. I don't see the full signal. The teacher in school ask me to make something like that for the assignment, ch0 led and ch1 the tx pin of arduino for the serial message:
Is it possible with this logic analyzer to see something like that? (and for me to check if everything works)
