2015-07-31Prevent losing bytes in HardwareSerial::end()Matthijs Kooijman
end() already waited for the buffer to be empty, but then there could still be two bytes in the hardware registers that still need to be transmitted (which were dropped or kept in the buffer, depending on the exact timing). This changes the wait loop to a call to the flush() function, which already takes care of really waiting for all bytes to be transmitted, meaning it is safe to turn off the transmitter.
2015-07-31Add Serial_::readBreak() to process SEND_BREAK requestsMatthijs Kooijman
This allows detecting when the USB host sends a break request and what the value of the request was. See the comments in USBAPI.h for details. This just modifies the avr core, not the sam core.
2015-07-31Expose serial settings from CDC virtual serial portMatthijs Kooijman
This allows a sketch to find out the settings chosen by the USB host (computer) and act accordingly. Other than reading the DTR flag and checking if the baudrate is 1200, the regular CDC code doesn't actually use any of these settings. By exposing these settings to the sketch, it can for example copy them to the hardware UART, turning the Leonardo into a proper USB-to-serial device. This can be useful to let the computer directly talk to whatever device is connected to the hardware serial port (like an XBee module). The Teensy core already supported these methods. This code was independently developed, but the method names were chosen to match the Teensy code, for compatibility (except that `dtr()` and `rtr()` return `bool`, while the Teensy version return a `uint8_t`). This change is applied to both the avr and sam cores, which have a very similar CDC implementation.

2015-07-16save RAM content overridden by bootloader magicMartino Facchin
and restore it in case of aborted reboot use RAMEND-1 as suggested by @yyyc514 in PR #2474 of course it's not a real solution but we cannot force everyone to update the bootloader using an external programmer

2015-07-16Check for __cplusplus >= 201103L as well as __GXX_EXPERIMENTAL_CXX0X__Matthijs Kooijman
Gcc 4.8 defines __cplusplus as 201103L, so we can check for that now. It still also defines __GXX_EXPERIMENTAL_CXX0X__, but this could help on other compilers, or if gcc ever decides to stop defining the experimental macro.
2015-07-03Removed a handful of SVN expansion keywords. See #277Federico Fissore
2015-06-18Warn about increasing HardwareSerial buffers to > 256Matthijs Kooijman
Properly supporting bigger buffers need better atomicity code, which isn't implemented yet. Until it is, best to add a warning. See #2405.

2015-05-22delayMicroseconds(): added support for 1Mhz, 12Mhz and 24MhzCano
1Mhz is a default clock speed on Atmega328, many users run it on the internal 1Mhz clock to save battery power. Up until now delayMicroseconds() function wasn't taking this frequencies into an account.
