Transfers over the SPI1 channel of the SAME70 working
Refactored GCodeBuffer for two data types:
1. For string-based inputs (standard text-based approach)
2. For binary data transfers as used in the new SPI protocol (untested)
Added OpenOCD script for SAME70 <-> Atmel ICE
Fixed relative workspace paths in the linker settings again
Enhancements
=========
Added support for RTD temperature sensors
When cancelling a print, if cancel.g exists then run it instead of
turning heaters off
Improved file upload speed over the web interface
Chamber heater is now exempted from timeout
Pressure advance now reduces maximum extruder jerk setting by a smaller
amount when the extruder steps/mm is high
The Duet no longer reports itself as an Arduino Due and has its own
Windows driver
Added experimental "maximum average printing acceleration" feature
Try to improve speed of getting file information in Print Monitor
Bug fixes
======
Simulation mode was not working properly
External driver support code sometimes failed to enable the associated
drives
Fixed potential overflow if a user attempted to use non-existent driver
9 on a Duet 0.6
M408 status requests were not handled when in simulation mode
Removed hard coded PATH in project
