Previously, during the build, the full package_index.json was downloaded
and distributed with the Arduino IDE.
This lead to a situation where it was difficult to test new AVR cores
before publishing them to the public package_index.json.
Now the bundled AVR core is specificed in the file:
`hardware/package_index_bundled.json`
this index is loaded from the IDE at startup and the package_index.json
is overlayed on it.
This should also solve part of #5143 (Repeatable builds and snapshots of
package/library indexes)
On Linux, setting autosuspend_delay_ms to N and control to auto allows the host pc to suspend the peripheral. Some Linux distro (Ubuntu, Mint) apply this behaviour by default.
If the sketch's prints where less frequent than N milliseconds the sketch prints would never arrive.
This patch allows sending a remote wakeup event to unsuspend the peripheral and allow the serial prints to be received.
to allow WebUSB development, provide a way to change the USB_VERSION reported
using an additional core.
The additional (webUSB) core will survive IDE and AVR core updates
Fixes that more complex methods (like Stream::print(float)) do not work properly.
Without this fix, Wire.print(1.01f); results in '1' because Print::printFloat(double, uint8_t) performs multiple print() and therefore twi_transmit calls. Also Wire.println("Heyho"); results only in a newline character.
In an excess of confidence, these defines were added to Leonardo's variant.h
3rd party boards sometimes avoid inheriting this variant but they still define USBCON, thus breaking the build
As I was not able to base the return types of `begin()` & `end()` off the c_str() function, I have changed the source so the features can be used by C++98 code, while still allowing ranged loops in C++11.
Replaces #4280, only checks for the bootloader once
Tested with Hoodloader2, should work with every LUFA-derived bootloader released after 2014 (.apitable_signatures section must be placed at end of the flash)
BootloaderAPITable.S :
.global BootloaderAPI_Signatures
BootloaderAPI_Signatures:
.long BOOT_START_ADDR ; Start address of the bootloader
.word 0xDF00 ; Signature for the CDC class bootloader
.word 0xDCFB ; Signature for a LUFA class bootloader
makefile:
BOOT_API_LD_FLAGS += $(call BOOT_SECTION_LD_FLAG, .apitable_signatures, BootloaderAPI_Signatures, 8)
