5 years ago The last line in the sketch tries to substract an int64_t (long long integer) from a uint32_t (unsigned long integer. You can make the sketch compile and run by changing the mentioned line into:
Serial.println(millis() - (uint32_t)sbus.getLastTime());
The issue is in the example sketch, not in the library (unless getLastTime wasn't supposed to return an int64_t).
When I run a verify I get the error:
