  • Regards, done compiling! What do you think about it? Why author set these values empty? Commented Apr 2, 2015 at 4:00

    He might have had another file, that he didn't upload to github. You do have an idea of what these values do? Because TXB8 is bit 0 from the register, so instead of using 0, you can use a define or definition, which is easier to understand. Also, you should check the error message when it won't compile. error: ‘TXB8’ was not declared in this scope Which mean that the compiler could't find the variable 'TXB8'. So either missing a variable, out of scope, or missing a define ;D And if you look at the code on that position, you should see what is missing there. Commented Apr 2, 2015 at 6:05
  • I asked him at github about this. In general, this library allows to connect mdb bus with PC through arduino Commented Apr 2, 2015 at 6:08
  • btw, it's still don't work on windows. I get this: C:\Users\User\Documents\Arduino\libraries\MdbBillValidator\MdbSerial.cpp:554:135: error: expected ')' before numeric constant MdbSerial MdbPort1(&rx_buffer1, &tx_buffer1, &UBRR1H, &UBRR1L, &UCSR1A, &UCSR1B, &UCSR1C, &UDR1, RXEN1, TXEN1, RXCIE1, UDRIE1, U2X1 UCSZ12, UCSZ11, UCSZ10, UPM11, UPM10, UMSEL11, UMSEL10); Commented Apr 2, 2015 at 6:22
