2021-01-06Allow disabling CDC with -DCDC_DISABLEDDaniel Gibson
Sometimes Arduino-based USB devices don't work because some hardware (like KVM switches) gets confused by the CDC sub-devices. This change makes it relatively easy to disable CDC at compiletime. Disabling it of course means that the serial console won't work anymore, so you need to use the reset button when flashing. CDC_DISABLED is also used in ArduinoCore-samd for the same purpose. based on https://github.com/gdsports/usb-metamorph/tree/master/USBSerPassThruLine See also https://github.com/NicoHood/HID/issues/225 and https://github.com/arduino/Arduino/issues/6387 and https://forum.arduino.cc/index.php?topic=545288.msg3717028#msg3717028

Update platform specification URLs in configuration files
2020-11-02Update platform specification URLs in configuration filesper1234
The Google Code URL in boards.txt is very outdated. The URL in platform.txt is to a more recent home of the content, which has been replaced with a link to the new location, but while I'm updating boards.txt, I might as well point both URLs to the real page.

Improve reading ADC result
2020-11-01Improve reading ADC resultVitaly Shmagun
7.3.0-atmel3.6.1-arduino7 gcc fails to optimize separate reading from ADCL and ADCH. It produces additionally three eor commands or in some cases two mov commands in the assembly code (see discussion #344). These commands swap register contents before store them to data area. So they are completely unnecessary. Reading ADC result with ADC macro fixes it and gcc generates the right code..

Improve and complete implementation of new/delete
2020-09-17Use std::size_t in new/deleteMatthijs Kooijman
The standard dictates that `std::size_t` is used, rather than the plain `size_t` type. Even though these types are usually, if not always, exactly the same type, other code might assume that `std::size_t` is actually used and thus also available under that name after including `<new>`. This fixes that by using the right type. One challenge is that it is usually declared in headers that we do not have available, so this just defines the `std::size_t` type in the `<new>` header to work around that.
2020-09-17Optionally let new terminate on allocation failureMatthijs Kooijman
This is currently disabled, keeping the old behavior of returning NULL on failure, but should probably be enabled in the future as code that does want to do a null check has had a chance to switch to the more portable nothrow versions. When enabled, allocation failure calls the weak `std::terminate()`, which calls `abort()` by default, but can be replaced by user code to do more specific handling. To enable this, a macro must be defined (in new.cpp or on the compiler commandline). This fixes part of #287.
2020-09-17Make zero-sized new standards-compliantMatthijs Kooijman
This fixes part of #287.
2020-09-17Call std::terminate on pure or deleted virtual functionsMatthijs Kooijman
These are special functions that are presumably put into vtables for deleted or pure virtual functions. Previously, this would call `abort()` directly, but calling `std::terminate()` achieves the same effect, but allows user code to change the behavior (e.g. to print to serial, blink leds or whatever makes sense).
2020-09-17Add weak `std::terminate()` implementationMatthijs Kooijman
This allows calling it from other places later. The default implementation calls `abort()`, but making it weak allows user code to override this function (either directly, or by including a library like uclibc++ that implements `std::set_terminate()`). Note that this does not add a declaration for this function, since the standard dictates this to be in `<exception>`, but we cannot meaningfully or completely implement that header, so better leave it to be overridden by e.g. libraries like uclibc++.
2020-09-17Allow overriding selected operator new and delete functionsMatthijs Kooijman
This makes these functions weak, so that a sketch or library can replace them. This does not apply to all of these operators, only for the ones that the C++ standard specifies as replaceable.
2020-09-17Clean up and complete `<new>` headerMatthijs Kooijman
This makes this header complete up to including C++14, except two exception classes that cannot be defined without `<exception>`. The functions related to the "new_handler" are declared but not actually defined, to prevent overhead and complexity. They are still declared to allow implementing them in user code if needed. This makes the implementation of all operator new and delete functions comply with the C++11/C++14 specification in terms of which should be actually implemented and which should be delegate to other functions. There are still some areas where these implementations are not entirely standards-compliant, which will be fixed in subsequent commits. This fixes part of #287 and fixes #47.
2020-09-17Swap new and new.h header filesMatthijs Kooijman
Originally, the Arduino core used "new.h", rather than the standard "new", probably because the implementation was incomplete, and for the most commonly used new and delete operators, no include is needed at all (they are defined implicitly by the compiler). However, now Arduino does expose the "new" name, as an alias for the older "new.h". Given that the standard name is "new", it makes more sense to put the actual content in "new", and make "new.h" a compatibility header that includes "new" instead of the other way around.
