The New Version of main.cpp
#include <Arduino.h>
int main(void)
{
init();
#if defined(USBCON)
USBDevice.attach();
#endif
setup();
for (;;) {
loop();
if (serialEventRun) serialEventRun();
}
return 0;
}
Looking at the source, there are two interesting items to note. First,
main.cpp
now looks to see if a USB
connection is defined and attached. Second, the
void loop()
code runs, and then a serial event is checked for.
If the event is found, then the code runs it.
Updated Serial Object
Sending data from serial is now asynchronous. The
serial
object depends on a parent object called
stream
, so it is
included automatically with
HardwareSerial.h
in your main sketch.
Updated Stream Class
The
Stream
class has been updated. This is part of the serial object and provides the search, find, and parse value
functions that the
HardwareSerial
object uses.
Constructor
The constructor simply sets the timeout for the serial port to a default of 1000 ms.
Stream() {_timeout=1000;}
Member Functions
The member functions are shown in Table
1-1
