I have an arduino uno with atmega328p controller.

I found the code to deal with some specific uart protocol, named mdb: https://github.com/Bouni/MateDealer/tree/master/arduino

But it's compiled just for atmega2560 controller: https://github.com/Bouni/MateDealer/blob/master/arduino/makefile#L42

If I replace it by atmega328p or atmega328, I get the error:

I've tried to play with compilers (default is gnu99) and so on, but with no success. Why I have this trouble? How can I compile this code for upload it to arduino?

I'm the author of the MateDealer project and I never had the intention to port it to other boards than the Arduino Mega2560!

Ignacio Vazquez-Abrams is absolutely right, the Arduino Mega2560 is the only board with more than 1 serial port (Yes there is the Due and the Leonardo, but those would require major changes to the code).

The fastest way to get the code running is by using a Mega2560, but be warned, the code might be bugy as hell ;-)

Thank you! Problem solved! –  asiniy 2 days ago

The '328 only has a single USART. You will need to remove all references to USARTs beyond the first as well as the numeric suffix from the USART register names in order to get it to compile.

So, do you mean that I can't read data from MDB protocol and send it to the serial port of my computer to read it in the display? –  asiniy Mar 12 at 19:13

If you require more than one USART to do so then no, you can't. You could try a serial UART, but this is beyond the scope of this question. –  Ignacio Vazquez-Abrams Mar 12 at 19:14
    
Can I use one usart for connect mdb and the second one for connect to serial of my computer? –  asiniy Mar 12 at 19:22
    
Again, you don't have 2 USARTs. –  Ignacio Vazquez-Abrams Mar 12 at 19:26
    
SoftwareSerial library give me ability to connect by 2 uarts, but not in the same time. I need to stop 1st usart, then run 2nd. How do you think, can I implement something like this in pure c? –  asiniy Mar 13 at 2:54
