Hello everyone !
I was trying last days to find a logic analyzer for Arduino to debug a weather transmiter . After a lot of searches on the net I did find something but not for ATMEGA328 . It was a code writed for ATMEGA16 and with a software useful for reverse engineering protocols .
The original software use a serial communication 9600 bps and 4 digital inputs that can be recorded .
I was trying to modify the original software for ATMEGA328 - 16 MHZ and at this point , this is what I could do .

The big problem is that only one channel is working . I did not had time to find why . Maybe if anyone in here is interested and have time could take a look and try to figure out what is the problem .
Bye !
