It looks like the hash chip sends back the report data asynchronously. Is a PIC controller capable of concurrently clocking in results from multiple chips?
It's a wired OR bus, all outputs join together into one PIC input. The PIC does have a UART and amazingly I just hooked REPORT_P to that pin. Smiley Smiley What's even better is it has IOC (interrupt on change) so I don't have to poll it.
Are you assuming only one chip will report data at a time (i.e. data is never being sent concurrently by more than one chip)? I have a feeling all chips will report some kind of status not just when a good nounce was found. But I guess we won't know for sure until the communication protocol is released.
