In the example simple.cpp the reading of the digital port is not working. When I run the example the analog ports A0 and A1 are reported but the digital pin 2 are not. Apart from this problem, how to map the ports to pins? For example, if I want pin 7 to be reported which port I should pass as argument to "reportDigital (port, enable)".

Hello,

First, thank you very much for this library, nicely written.

I have used it with success on an Arduino Uno but did not managed to get it running with an Arduino Leonardo.

The difference is that the Arduino Leonardo provides the virtual serial port by itself so a new serial connexion do not reset the board and it is maybe the cause of the issue.

I have tried to use another Firmata client, pymata-aio and it works well with Arduinos Uno, Mega and Leonardo. But I would prefer to use a C++ library.

I will try to investigate a bit but I opened the issue to get your thoughts on that.

Thanks.

Using digitalWrite has no effect. The reason is a wrong definition of the message in format_constants.h

#define FIRMATA_SET_DIGITAL_PIN 0xF4

should be

#define FIRMATA_SET_DIGITAL_PIN 0xF5
