eff20deb27 Add ability to set interrupt priority for UART/USARTs. 2014-12-24 10:36:40 -05:00

2fedb00552 Switch all of the transmit interrupt code to UARTClass. Also, turn USARTClass into a stub because it did nothing differently from the UART code anyway. Now all serial ports use transmit interrupts. 2014-12-24 10:20:37 -05:00

a9735bf91f Fix atomicity issues in SPI::beginTransaction and SPI::endTransaction (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.

53e25d8b55 [avr] Improved SPI speed on 16bit transfer. 
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.

cd9a9e3fd7 Reduce avrdude verbosity 
Previously, when verbose uploads were enabled, avrdude was run with four
-v options, causing it to dump all raw bytes exchanged with the
bootloader. This floods the console so much that meaningful output
mostly disappears.

Most users probably want to enable verbose mode just to see what avrdude
command is ran. Furthermore, users that benefit from the raw bytes
dumped are perfectly capable of either running avrdude manually, or
modifying platform.txt. Given that, running avrdude with just one  -v
should be plenty.

This fixes #891.

04dba1e46f Fix off-by-one in String::substring 
When checking the `left` argument, it previously allowed having
left == len. However, this means the substring starts one past the last
character in the string and should return the empty string. In practice,
this already worked correctly, because buffer[len] contains the trailing
nul, so it would (re)assign the empty string to `out`.

However, fixing this check makes it a bit more logical, and prevents a
fairly unlikely out-of-buffer write (to address 0x0) when calling
substring on an invalidated String:

	String bar = (char*)NULL;
	bar.substring(0, 0);

86015f441e Simplify String::remove(unsigned int) 
Previously, this method calculated the length of the string from the
given index onwards. However, the other remove() method called already
contains code for this calculation, which is used when the count passed
in is too big. This means we can just pass in a very big count that is
guaranteed to point past the end of the string, shrinking the remove
method by a few bytes.

2068f88a21 Fix bounds check in String::remove() 
Previously, if you passed in a very big index and/or count, the
`index + count` could overflow, making the count be used as-is instead
of being truncated (causing the string to be updated wrongly and
potentially writing to arbitrary memory locations).

We can rewrite the comparison to use `len - index` instead. Since we
know that index < len, we are sure this subtraction does not overflow,
regardless of what values of index and count we pass in.

As an added bonus, the `len - index` value already needed be calculated
inside the if, so this saves a few instructions in the generated code.

To illustrate this problem, consider this code:

String foo = "foo";
Serial.println(foo.length()); // Prints 3
foo.remove(1, 65535); // Should remove all but first character
Serial.println(foo.length()); // Prints 4 without this patch

Not shown in this is example is that some arbitrary memory is written
as well.

2b90124e3d Remove unneeded check in String::remove(unsigned int)

flag -fno-threadsafe-static:

  int __cxa_guard_acquire(__guard *);
  void __cxa_guard_release (__guard *);
  void __cxa_guard_abort (__guard *);

The following empty stubs has been moved into their specific
module abi.cpp:

  void __cxa_pure_virtual(void) __attribute ((noreturn));
  void __cxa_deleted_virtual(void) __attribute ((noreturn));

10a89a1d8d Support Atmega8 (and similar that define PE instead of UPE) again 
These chips were previously supported, but since parity error checking
was added, this support has broken. Most chips define UPE0 (etc.) for
the parity error bit. Some chips don't have numbered UARTS so only
define UPE and even fewer define PE instead of UPE. This adds support
for those chips again.
