Fixing SPI communication with a delay as pointe out in #6395

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
2017-12-18Fix MCUs without MPCM0 registerMartino Facchin
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

2017-07-07Update comments to reflect Stream functions changed from private to protectedper1234
These functions were changed from private to protected in https://github.com/arduino/Arduino/commit/99f2a2755349784835130147e46cb61659b85893 but the comments were not updated at that time. In conjunction with equivalent pull requests to Arduino SAM Boards and Arduino SAMD Boards, solves https://github.com/arduino/Arduino/issues/6146.

2017-05-23Move the flush method from Stream to PrintMatthijs Kooijman
This method originally flushed pending input bytes, which makes sense in Stream. At some point it was changed to flush output bytes instead, but it was never moved to Print to reflect this. Since Stream inherits from Print, this should not really affect any users of the Stream or Print classes. However to prevent problems with existing implementations of the Print class that do not provide a flush() implementation, a default implementation is provided. We should probably remove this at some point in the future, though.

2017-03-07fix extended fuse bits for ethernet boardAdrien Descamps
Forgot to fix ethernet board in previous commit
2017-03-07Set unused bits of extended fuse to 1Adrien Descamps
Avrdude has changed the way it handle unused bits in the extended fuse for atmega 328 and atmega 168, they are now at 1 instead of 0. See http://svn.savannah.nongnu.org/viewvc?view=rev&root=avrdude&revision=1335 for more info. This causes avrdude to fail when one try to write the fuse with the unused bits at 0, because the value it read back is not the same than the one it tried to write. This commit fixes the fuse value for all boards that use atmega328 or 168.

2017-01-07Change double quotes to single quotesPatrick Roncagliolo
- "." is a string literal, and so is treated as the char '.' plus the null char '\0'. - Single quotes reduces the necessary memory for this literal to only one char instead. A string literal as the one actually present may require the use of the method "write(const char *str)", so there could be also a performance overhead. - Another reason to change quotes style is for consistency with line 235.
