VOR Supported O_C
Official Firmware:
The Official firmware support VOR since v1.36.
VOR must be enabled in the file "OC_options.h".
Modules without dedicate range button (1uO_c 4Robots) "VOR_NO_RANGE_BUTTON" should be enabled as well (for the option to change range by long pressing the "up" button).
Auto VOR preferences can be edited in the file "VBiasManager.h" (from line 97).
VOR/NON VOR Jumper:
1uO_c 4ROBOTS v2.X and Assembled SMD version of OCP allows you to change to NON VOR mode by changing the position of the jumper on the back of the module, In this case firmware should be used without the VOR options enabled.
Changing from VOR to NON VOR or vice versa requires recalibrating the module.
*In the VOR version - a long press on the "Up" button is used to switch between offsets
Pre Compiled HEX Files:
Official Firmware for 4ROBOTS (without range button)
Official Firmware for OCP and 1uO_c mk2 (with range button)
Hemisphere Suite:
This firmware version of Hemisphere with VOR support is experimental and may contain bugs, Plum Audio has no control over the integrity of this firmware and will not be supported by us.
If you have a module that only supports VOR calibration (version 1.X) or if you prefer to stay in VOR calibration you can try this firmware.
if your module is version 2 or higher you can calibrate the module to NON VOR and install the standard Hemisphere firmware distributed in the project's GitHub.
*In the VOR version - a long press on the "Up" button is used to switch between offsets
Recent Hemisphere Suite release with VOR support are locate in a different branch (ocplus) of O_C-HemisphereSuite repository, this branch is up-to-date copy of the master branch with VOR support added:
GitHub (ocplus branch)
Pre Compiled HEX File:
Hemisphere Suite for 1uO_c 4ROBOTS (without range button)
Hemisphere Suite for OCP and 1uO_c mk2 (with range button)
Known bugs: The calibration does not work properly in this version, please calibrate the module in the official firmware before installing Hemisphere.
