The CDC code presents itself as a virtual serial port. However, it also
sets the "bFunctionProtocol" value to 1, which means it supports
AT-commands, which is not actually the case. This might cause problems
with some software, such as ModemManager.
Originally, ModemManager would be very liberal with probing serial
devices, using a blacklist to prevent probing non-modems such as
Arduinos.
Since version 1.7.990, it has supported a "strict" mode where it tries to be
more restrained in what devices it probes. For CDC ACM devices, this
means it will only probe devices that claim to support AT-commands.
However, it also stopped applying the blacklist (intending to eventually
remove the blacklist), meaning it would again probe Arduinos.
This new strict policy is not the upstream default, but is enabled in
Debian (since Buster) and Ubuntu (since bionic 18.04.2).
The proper way to fix this, is to not claim AT comand support in the USB
device descriptor, which is what this commit does. The Arduino will
still show up as a virtual serial port, just not be probed by
ModemManager in strict mode.
For the commit that introduced the strict mode in ModemManager, see

Remove historic Arduino 0012 workaround in SoftwareSerial
|
|
|
|
|
|
Avoids unused variable warning if USB is enabled but pluggable USB is not
|
|
Putting the parameter names in these commonly used prototypes makes syntax help like VS Code's Intellisense work 99% more useful. Without them, it doesn't give you the names of the parameters and you have to remember the semantics yourself. :(

Remove commented out code for I2C interrupts on WInterrupts.c
|
|
These are currently implemented by the Wire library, on twi.c
|
|
Add USBDevice.isSuspended()
|
|
Add ATmega32U4-compatible Arduino as ISP programmer
|
|
Use of the stk500v1 protocol for Arduino as ISP does not work with native USB boards on Windows. The arduino protocol does.
However, the arduino protocol makes it more likely that boards with an external USB interface chip will require the auto-reset circuitry to be disabled to allow them to be used as Arduino as ISP. That adds extra complexity to a process already difficult for the average Arduino user.
For this reason, a new programmer using the arduino protocol is added specifically for using native USB boards as Arduino as ISP and the previous Arduino as ISP configuration is retained for use with all other boards.

This reverts commit b084848f2eaf9ccb3ac9a64ac5492d91df4706bf.
|
|
Based on code originally by Rob van der Veer <rob.c.veer@gmail.com>, this adds
USBDevice.isSuspended(), so user sketches can run custom code in their `loop`
methods after checking if the device is suspended or not.

Removed #undefs in SoftwareSerial.h that were marked as Arduino 0012 workaround and that broke several macros, including abs.

Casting to void is a well known trick for prevening 'unused parameter' warnings.

Fixing SPI communication with a delay as pointe out in #6395
|
|
|
|
Since we are now factory flashing obtiboot, 115200 is the new default upload speed. Adding a new entry to CPU menu is more explicit than adding an "upload speed" menu, and the bootloader path can be updated too.
Fixes https://github.com/arduino/Arduino/issues/4492

Make write to UDR and clearing of TXC bit in flush() atomic
to avoid race condition.
Fixes #3745 (second different issue introduced later but discussed
in the same issue)
|
|
Preserve values of configuration bits MPCMn and U2Xn.
Avoid setting other read-only bits for datasheet conformance.
