Added support for different size of TX and RX buffer sizes.
Added support for buffer sizes bigger than 256 bytes.
Added support for different size of TX and RX buffer sizes.
The default values remain the same. 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.
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.
The code used to say:
while (EFC0->EEFC_FSR & EEFC_FSR_FRDY == 0);
This triggered a compiler warning, which is why I looked at this line
more closely:
warning: suggest parentheses around comparison in operand of '&'
As the warning indicates, because the == operator has higher precedence
than the & operator, the compiler is interpreting this line as:
while (EFC0->EEFC_FSR & (EEFC_FSR_FRDY == 0));
Since EEFC_FSR_FRDY is defined as 1, (EEFC_FSR_FRDY == 0) is always
false (== 0) and this reduces to:
while (EFC0->EEFC_FSR & 0);
Which reduces to:
while (0);
So effectively this line is a no-op.
This commit adds parenthesis to restore the intended behaviour.
This was already fixed for HardwareSerial.cpp in #1863, but there was
one more case hidden in HardwareSerial_private.h.
The index attributes have been uint8_t for a while, so there is no point
in using int for local variables. This should allow the compiler to
generate slightly more efficient code, but (at least on gcc 4.8.2) it
also confuses the register allocator, causing this change to increase
code size by 2 bytes instead due to extra push/pop instructions (but
this will probably change in the future if the compiler improves).
