Still trying to get to grips with the USBFTDILoopback example from the USB Host 2.0 library. Any suggestions on what the author (Oleg Mazurov) is intending with this snippet? rcode = Ftdi.RcvData(&rcvd, buf); if (rcode && rcode != hrNAK) { ErrorMessage<uint8_t>(PSTR("Ret"), rcode); }…

Tonights newbe questions...

Why logicically AND the same variable?

Read it like this

if ((rcode != 0)&& (rcode != hrNAK))
