2014-11-25Fix atomicity issues in SPI::beginTransaction and SPI::endTransaction ↵Cristian Maglie
(Andrew Kroll) Previously, it could happen that SPI::beginTransaction was interrupted by an ISR, while it is changing the SPI_AVR_EIMSK register or interruptSave variable (it seems that there is a small window after changing SPI_AVR_EIMSK where an interrupt might still occur). If this happens, interruptSave is overwritten with an invalid value, permanently disabling the pin interrupts. To prevent this, disable interrupts globally while changing these values.

2014-11-25[avr] Improved SPI speed on 16bit transfer.Cristian Maglie
From https://github.com/arduino/Arduino/pull/2376#issuecomment-59671152 Quoting Andrew Kroll: [..this commit..] introduces a small delay that can prevent the wait loop form iterating when running at the maximum speed. This gives you a little more speed, even if it seems counter-intuitive. At lower speeds, it is unnoticed. Watch the output on an oscilloscope when running full SPI speed, and you should see closer back-to-back writes. Quoting Paul Stoffregen: I did quite a bit of experimenting with the NOP addition. The one that's in my copy gives about a 10% speedup on AVR.
