2019-03-09Re-wrote uploading section of READMEDavid Madison
The "hold and then release" reset process is what Arduino recommends but it never worked for me, the double reset is much more reliable.
2019-03-06Add auto-upload warning section to READMEDavid Madison

2019-03-06Merge pull request #2 from dmadison/xinputDavid Madison
XInput
2019-03-06Change manufacturer stringDavid Madison
2019-02-21Add USB connected API supportDavid Madison
Returns true if the device USB is configured. Although will still return true if the device has been configured and the USB data pins disconnected...
2019-02-21Change receive endpoint to double-bankedDavid Madison
No reason not to take advantage of this feature, although with the interrupt in place I doubt it will be useful.
2019-02-21Use endpoint number defines for ep allocationDavid Madison
2019-02-21Add USB receive callback to USB ISRDavid Madison
Using the OUT endpoint interrupt
2019-02-21Add XInput USB APIDavid Madison
2019-02-19Change VID and PID in boards.txtDavid Madison
Better to set these where intended so they can be easily overridden if need be.
2019-02-19Add XInput endpoint number definesDavid Madison
2019-02-19Allocate XInput endpoint memoryDavid Madison
2019-02-19Modify endpoint numbers to be sequentialDavid Madison
Easier for the AVR to deal with the memory if the in/out numbers aren't paired.
2019-02-19Add XInput string descriptorsDavid Madison
2019-02-19Add XInput device and config descriptorsDavid Madison
2019-02-17Removed USB CDC SerialDavid Madison
This will compile but will NOT enumerate properly without a config descriptor. You've been warned...
2019-02-15Replace Serial with nullDavid Madison
Allows sketches using Serial to compile but discards all data
2019-02-15Fix warning related to disabling Pluggable HIDDavid Madison
Unused if pluggable USB is not enabled. Should submit a PR to fix this in the main repo...
2019-02-15Disable Pluggable USBDavid Madison
Not compatible with XInput, which requires a static descriptor
2019-02-15Remove HID libraryDavid Madison
Can't be used since PluggableHID and XInput are mutually exclusive
2019-02-15Use "w/ XInput" suffix on all board namesDavid Madison
Distinguish at a glance from the 'normal' boards in the IDE
2019-02-15Merge pull request #1 from dmadison/forkingDavid Madison
Forking
2019-02-15Remove non-USB boardsDavid Madison
Removes boards from boards.txt, bootloaders for those boards, and variants for those boards. As none of these boards support USB there's no reason to keep them around.
2019-02-15Delete 'firmwares' folderDavid Madison
2019-02-15Delete 'extras' folderDavid Madison
2019-02-15Delete programmers.txtDavid Madison
2019-02-15Change platform name to XInputDavid Madison
Required to separate this board set from the built-in AVR core

2018-02-19Add menu for Nano with Optiboot bootloaderMartino Facchin
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
2017-12-18Fix MCUs without MPCM0 registerMartino Facchin
2017-11-13Fix flush hanging issueJohn Holman
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)
2017-11-13Improve how TXCn bit is cleared in USCRnA registerJohn Holman
Preserve values of configuration bits MPCMn and U2Xn. Avoid setting other read-only bits for datasheet conformance. See #3745
2017-11-13Prevent buffer retransmission when transmit buffer is emptyJohn Holman
Moving the head buffer pointer and setting interrupt flag is now atomic in write(). Previously an intervening ISR could empty the buffer before the second ISR is triggered causing retransmission. Fixes: #3745 (original issue only)
2017-11-13Create macro to guard critical sections for large transmit buffersJohn Holman
New macro TX_BUFFER_ATOMIC makes the following code block atomic only if the transmit buffer is larger than 256 bytes. SREG is restored on completion. The macro is then used to simplify code for availableForWrite()
2017-11-13UnConfigured I2C Slave ISR Causing Rebootchuck todd
In a MultiMaster I2C environment, The Default value of 0xFE in the TWAR cause the Arduino to respond as an I2C Slave device at address 0x7f. If the Wire.h library was not configured as a I2C Slave, `Wire.begin(slaveID);` the Callbacks for `twi_onSlaveTransmit()` and `twi_onSlaveReceive()` are never initialized. But, they are called during servicing the TWI ISR. This causes a reboot of the Arduino by jumping to an uninitialized function address (0). So, this fix initializes them to the Default Wire.h handler which will respond correctly even during Master Mode operations. A MASTER MODE only Arduino will respond to all Slave Calls that match TWAR, Unless the TWEA bit is disabled outside of Master Transactions. Chuck. It also initialized the TWAR to the General Call ID (0x0) and Disables General Call responses. Chuck.
2017-11-13Always read key to check for new LUFA bootloaderScott Allen
Instead of checking for the NEW_LUFA_SIGNATURE once in program memory and then setting a flag which is used for further checks, a function is used that always checks program memory directly. If a flag is used, there's a slight chance that its location in RAM could fall on MAGIC_KEY_POS. In this case, an aborted USB auto-reset sequence may fail.
2017-11-13Don't use line coding to trigger USB auto-resetScott Allen
An auto-reset invoked using USB CDC is triggered by the port closing (when set to 1200 baud). Closing of the port is indicated by DTR going inactive. There is no need to have auto-reset invoked by a CDC_SET_LINE_CODING command. Only the CDC_SET_CONTROL_LINE_STATE command, which indicates a change in the state of DTR, should be used.
2017-11-13Save/restore the watchdog during USB auto-resetScott Allen
The state of the watchdog timer is saved during a USB auto-reset and then restored if the reset is aborted, in case the sketch is using the watchdog.
2017-11-13Fix save/restore of magic key location during resetScott Allen
In the USB CDC code to invoke an auto-reset, the magic key location could be restored before it had actually been saved. The sketch would then have a corrupted value at this location. This fix prevents the value from being restored if it hasn't previously been saved.
