In commit 0e97bcb (Put each HardwareSerial instance in its own .cpp
file), the serial event handling was changed. This was probably a
copy-paste typo.
The effect of this bug was that SerialEvent3 would not run, unless
SerialEvent2 was defined, but also that if SerialEvent2 is defined but
SerialEvent3 is not, this could cause a reset (call to NULL pointer).
This closes#1967, thanks to Peter Olson for finding the bug and fix.
Added support for buffer sizes bigger than 256 bytes.
Added possibility to overrule the default size.
Added support for different size of TX and RX buffer sizes.
The default values remain the same. You can however specify a different
value for TX and RX buffer
Added possibility to overrule the default size.
If you want to have different values
define SERIAL_TX_BUFFER_SIZE and SERIAL_RX_BUFFER_SIZE on the command
line
Added support for buffer sizes bigger than 256 bytes.
Because of the possibility to change the size of the buffer sizes longer
than 256 must be supported.
The type of the indexes is decided upon the size of the buffers. So
there is no increase in program/data size when the buffers are smaller
than 257

Fixes#1203.
The original patch was introduced to workaround a problem with ArduinoISP reported
in #995. After some debugging it seems caused by a glitch in RXTX library,
more discussion here: https://github.com/arduino/Arduino/issues/1203
JSSC, on unix based systems like linux and MacOSX, when listing serial ports
tries to open each port to ensure its existence. While this check works well for
linux ports /dev/ttyS0..31, it leads to unexpected behaviuors on MacOSX in
particular with USB-CDC virtual serial ports.
This patch disable the check and keep it enabled only for linux ttySxx ports.
This adds also tty.* and cu.* to the list of available serial ports on MacOSX.
Members of this array are later passed to functions that accept
non-const pointers. These functions probably don't modify their
arguments, so a better solution would be to update those functions to
accept const pointers. However, they look like third-party code, so that
would require changing the code again on every update. Removing const
here fixes at least the compiler warning for now.
This helps towards #1792.
This makes the declaration of sprintf available, so the function is not
implicitely declared, which triggers two compiler warnings.
This helps towards #1792
A bunch of functions have parameters they do not use, but which cannot
be removed for API compatibility.
In syscalls_sam3.c, there are a lot of these, so this adds an "UNUSED"
macro which adds the "unused" variable attribute if supported (GCC
specific), or is just a noop on other compilers.
In CDC.cpp, there's only three of these variables, so this commit just
forces a dummy evaluation of them to suppress the warnings.
This helps towards #1792.
peekNextDigit() returns an int, so it can return -1 in addition to all
256 possible bytes. By putting the result in a signe char, all bytes
over 128 will be interpreted as "no bytes available". Furthermore, it
seems that on SAM "char" is unsigned by default, causing the
"if (c < 0)" line a bit further down to always be false.
Using an int is more appropriate.
A different fix for this issue was suggested in #1399. This fix helps
towards #1728.
All the while() loops that check for the SPI transfer to be complete have the
semi-colon immediately after the closing parenthesis. This both causes a
compiler warning of "warning: suggest a space before ';' or explicit braces
around empty body in 'while' statement", and is considered a less-than-ideal
programming practice. This patch breaks the semi-colon on to the next line,
both eliminating the compiler error and making the code more readable.
In all probability the test should be moved into a macro or a inlineable
sub-routine.
