2014-07-17Cast empty string to char* to fix compiler warningMatt Robinson
Stream::find(char *target) passes an empty terminator string to Stream::findUntil(char *target, char *terminator) which caused a compiler warning with the updated toolchain, so cast it to a char*.

2014-06-25Support Atmega8 (and similar that define PE instead of UPE) againMatthijs Kooijman
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. Closes: #2137

2014-05-30Fix of a bugAmulya Kumar Sahoo
Stream::find(char *target) passes NULL as “terminator” to Stream::findUntil(char *target, char *terminator), which immediately dereferences it by passing it on to strlen(): bool Stream::find(char *target) { return findUntil(target, NULL); } // as find but search ends if the terminator string is found bool Stream::findUntil(char *target, char *terminator) { return findUntil(target, strlen(target), terminator, strlen(terminator)); }

2014-05-24Improve CDC read codePaul Brook
Read CDC data from USB FIFO on demand instead of in ISR. Remove superfluous ring buffer. Signed-off-by: Paul Brook <paul@nowt.org>
2014-05-24Fix race condition in USB CDC transmitPaul Brook
If the Start of Frame interrupt triggers just after the call to USB_SendSpace in USB_Send then we can get data loss. When the first bank is full and the second partially full, the SOF handler will release the second bank via USB_Flush. Data is then lost due to overflow as USB_Send continues writing data to the now-closed bank. Fix this by re-checking the FIFO status inside LockEP, immediately before doing the data write.

2014-05-16Support TIMER1CMatthijs Kooijman
Some devices, such as the atmega2560 or the atmega256rfr2 have a timer1c output. It seems this output is not connected to anything on the Arduino Mega, but this allows using it on third party hardware nonetheless.

2014-05-06Remove unneeded register and ISR names in HardwareSerialx.cppMatthijs Kooijman
Before, HardwareSerial1+.cpp were a copy of HardwareSerial1.cpp with all 0's replaced by the corresponding number. This would mean that e.g. the Serial1 object would use the UBRRL register instead of UBRR1L when it was defined, or the USART_RX_vect instead of USART1_RX_vect. In practice, this would neve actually cause problems, since: - No avr chip currently has both the non-numbered registers as well as numbered registers. - HardwareSerial.h would only define HAVE_HWSERIALx when the corresponding numbered register is defined (except for HAVE_HWSERIAL0, which is also defined when the unnumbered registers are present). Furthermore, before both the UARTx_xx_vect and USART_x_xx_vect was used. Looking at the include files, only UART1_xx_vect is actually used (by iom161.h), the others use USARTx_xx_vect. For this reason, HardwareSerial1.cpp keeps the preprocessor conditional to select either UART or USART and the other files use USART unconditionally. While we're here, also fix the compiler error message when no valid ISR name was found (it previously said "for the first UART" in all cases).

2014-03-27Fix typo in SerialEvent3 handlingMatthijs Kooijman
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.
2014-03-24Added support for different size of TX and RX buffer sizes.jantje
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

2014-02-19Don't store peeked characters in a char variableMatthijs Kooijman
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.
2014-02-19Instead of #defining true and false, include stdbool.hMatthijs Kooijman
In C++, true and false are language keywords, so there is no need to define them as macros. Including stdbool.h in C++ effectively changes nothing. In C, true, false and also the bool type are not available, but including stdbool.h will make them available. Using stdbool.h means that we get true, false and the bool type in whatever way the compiler thinks is best, which seems like a good idea to me. This also fixes the following compiler warnings if a .c file includes both stdbool.h and Arduino.h: warning: "true" redefined [enabled by default] #define true 0x1 warning: "false" redefined [enabled by default] #define false 0x0 This fixes #1570 and helps toward fixing #1728. This only changed the AVR core, the SAM core already doesn't define true and false (but doesn't include stdbool.h either).
2014-02-19Use a union in IPAddress for uint8_t[] <-> uint32_t conversionMatthijs Kooijman
Previously, pointer casting was used, but this resulted in strict-aliasing warnings: IPAddress.h: In member function ‘IPAddress::operator uint32_t() const’: IPAddress.h:46:61: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] operator uint32_t() const { return *((uint32_t*)_address); }; ^ IPAddress.h: In member function ‘bool IPAddress::operator==(const IPAddress&) const’: IPAddress.h:47:81: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] bool operator==(const IPAddress& addr) const { return (*((uint32_t*)_address)) == (*((uint32_t*)addr._address)); }; ^ IPAddress.h:47:114: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] bool operator==(const IPAddress& addr) const { return (*((uint32_t*)_address)) == (*((uint32_t*)addr._address)); }; Converting between unrelated types like this is commonly done using a union, which do not break the strict-aliasing rules. Using that union, inside IPAddress there is now an attribute _address.bytes for the raw byte arra, or _address.dword for the uint32_t version. Since we now have easy access to the uint32_t version, this also removes two memcpy invocations that can just become assignments. This patch does not change the generated code in any way, the compiler already optimized away the memcpy calls and the previous casts mean exactly the same. This is a different implementation of a part of #1399 and it helps toward fixing #1728.
2014-02-18In HardwareSerial::_rx_complete_irq, don't use int for buffer indexMatthijs Kooijman
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).
