Removes unnecessary if branch (because length is checked in while statement below the if-clause).

Avoids unused variable warning if USB is enabled but pluggable USB is not
2019-01-21Add parameters names to common prototypesPaul R. Nash
Putting the parameter names in these commonly used prototypes makes syntax help like VS Code's Intellisense work 99% more useful. Without them, it doesn't give you the names of the parameters and you have to remember the semantics yourself. :(

Add ATmega32U4-compatible Arduino as ISP programmer
2018-12-19Add ATmega32U4-compatible Arduino as ISP programmerper1234
Use of the stk500v1 protocol for Arduino as ISP does not work with native USB boards on Windows. The arduino protocol does. However, the arduino protocol makes it more likely that boards with an external USB interface chip will require the auto-reset circuitry to be disabled to allow them to be used as Arduino as ISP. That adds extra complexity to a process already difficult for the average Arduino user. For this reason, a new programmer using the arduino protocol is added specifically for using native USB boards as Arduino as ISP and the previous Arduino as ISP configuration is retained for use with all other boards.

2018-12-11Add USBDevice.isSuspended()Gergely Nagy
Based on code originally by Rob van der Veer <rob.c.veer@gmail.com>, this adds USBDevice.isSuspended(), so user sketches can run custom code in their `loop` methods after checking if the device is suspended or not. Signed-off-by: Gergely Nagy <algernon@keyboard.io>
2018-11-26Removed historic Arduino-0012 workaroundFlorian Schweiger
Removed #undefs in SoftwareSerial.h that were marked as Arduino 0012 workaround and that broke several macros, including abs. See https://github.com/arduino/ArduinoCore-avr/issues/30

The standard mandates that placement new should be have a noexcept specifier.

2018-02-19Add menu for Nano with Optiboot bootloaderMartino Facchin
Since we are now factory flashing obtiboot, 115200 is the new default upload speed. Adding a new entry to CPU menu is more explicit than adding an "upload speed" menu, and the bootloader path can be updated too. Fixes https://github.com/arduino/Arduino/issues/4492

2017-11-13Fix flush hanging issueJohn Holman
Make write to UDR and clearing of TXC bit in flush() atomic to avoid race condition. Fixes #3745 (second different issue introduced later but discussed in the same issue)
2017-11-13Improve how TXCn bit is cleared in USCRnA registerJohn Holman
Preserve values of configuration bits MPCMn and U2Xn. Avoid setting other read-only bits for datasheet conformance. See #3745
2017-11-13Prevent buffer retransmission when transmit buffer is emptyJohn Holman
Moving the head buffer pointer and setting interrupt flag is now atomic in write(). Previously an intervening ISR could empty the buffer before the second ISR is triggered causing retransmission. Fixes: #3745 (original issue only)
2017-11-13Create macro to guard critical sections for large transmit buffersJohn Holman
New macro TX_BUFFER_ATOMIC makes the following code block atomic only if the transmit buffer is larger than 256 bytes. SREG is restored on completion. The macro is then used to simplify code for availableForWrite()
2017-11-13UnConfigured I2C Slave ISR Causing Rebootchuck todd
In a MultiMaster I2C environment, The Default value of 0xFE in the TWAR cause the Arduino to respond as an I2C Slave device at address 0x7f. If the Wire.h library was not configured as a I2C Slave, `Wire.begin(slaveID);` the Callbacks for `twi_onSlaveTransmit()` and `twi_onSlaveReceive()` are never initialized. But, they are called during servicing the TWI ISR. This causes a reboot of the Arduino by jumping to an uninitialized function address (0). So, this fix initializes them to the Default Wire.h handler which will respond correctly even during Master Mode operations. A MASTER MODE only Arduino will respond to all Slave Calls that match TWAR, Unless the TWEA bit is disabled outside of Master Transactions. Chuck. It also initialized the TWAR to the General Call ID (0x0) and Disables General Call responses. Chuck.
2017-11-13Always read key to check for new LUFA bootloaderScott Allen
Instead of checking for the NEW_LUFA_SIGNATURE once in program memory and then setting a flag which is used for further checks, a function is used that always checks program memory directly. If a flag is used, there's a slight chance that its location in RAM could fall on MAGIC_KEY_POS. In this case, an aborted USB auto-reset sequence may fail.
2017-11-13Don't use line coding to trigger USB auto-resetScott Allen
An auto-reset invoked using USB CDC is triggered by the port closing (when set to 1200 baud). Closing of the port is indicated by DTR going inactive. There is no need to have auto-reset invoked by a CDC_SET_LINE_CODING command. Only the CDC_SET_CONTROL_LINE_STATE command, which indicates a change in the state of DTR, should be used.
2017-11-13Save/restore the watchdog during USB auto-resetScott Allen
The state of the watchdog timer is saved during a USB auto-reset and then restored if the reset is aborted, in case the sketch is using the watchdog.
2017-11-13Fix save/restore of magic key location during resetScott Allen
In the USB CDC code to invoke an auto-reset, the magic key location could be restored before it had actually been saved. The sketch would then have a corrupted value at this location. This fix prevents the value from being restored if it hasn't previously been saved.

2017-07-25Fixed Serial Port Argument That May Include SpacesVarun Mehta
Other paths in avrdude.upload.pattern are wrapped in double quotes, and this -P{serial.port} causes issues with some platforms. This allows serial port devices which include spaces and other characters. Without this fix a /dev/tty* or /dev/cu* device that includes a space in its name gets truncated when passed to avrdude. Error messages returned from avrdude are cryptic, and workarounds (symlinks) are prone to failure. Fixes #3693
