SimuCUBE firmware files

Stable SimuCUBE firmware is not yet published. Until then, please consider using MMos firmware for production purposes.

Please note that this version history table only lists collected changes after each publicly released version.

Date	Firmware / Configuration Tool version	Included IONI firmware version	Closed / Open / Official	FW file	Description/changes/new features
	0.8.20 / 0.8.20	10630	Public beta release		Planned release before end of 2017. Includes new Beta IONI firmware, event logging, Bumbstop damping improvement, and some FFB improvements.
November 9th, 2017	0.8.12 / 0.8.11	10601	Public beta release	[1]	Hotfix release: Device Gain is again calculated correctly. It had been removed by mistake. Torque command update rate has been increased to 2500 Hz. Beginning from early version 0.5.0, it was reduced to 1250 Hz, to overcome unrelated issue, which was then forgotten until now.
November 9th, 2017	0.8.11 / 0.8.11	10601	Public beta release	[2]	New features: These DirectInput effects and features have been implemented that were not previously implemented: Friction, Damping, Device Gain Sliders to set general strength multiplier for friction and damper have been added into the UI Device gain is being set when a game starts, so no slider for it is required in the UI. Previously exported simucubeprofiles.ini file with these settings missing will load. The DirectInput Friction and Damping gains will be set at 50% for those profiles. Saved setting on SimuCUBE flash memory have 0% setting for these. User must change them manually to some sensible value for each profile. Games tested: Assetto Corsa, Dirt Rally, Automobilista (Pure FFB no effects is supported; effects -settings might not work correctly) New Tabbed UI with much more refined looks Tabs! Effect types are shown in the UI, with bolded font for those effects that game is changing actively Button has been added to clear effect memory and reset Device Gain. This is useful when game has crashed and left effects running. Motor fault reason codes are being read and shown directly in the user interface. However, faults are cleared if they ever happen, so the indicator will disappear too soon. Usefulness of this feature is going to be improved in the next release. Confirmation dialog for profile deletion has been added. Lots of other small tidy-ups and fixes Bug fixes: Importing analog axis settings from the .ini file didn't load invert axis -settings correctly. Known issues: Estimated torque output calculation is stll likely wrong. When using high forces and having the reconstruction filter at high value, the wheel might go numb and give a feeling of saturated forces. This is being investigated.
October 25th, 2017	0.8.4 / 0.8.4	10601	Public beta release	[3]	Changes and fixes: Strength setting of the default profile was not applied at startup. Read-only safe profile was applied inconsistently when running the Motor Configuration Wizard SimuCUBE Hardware Revision information is now shown in the configuration tool Removed unnecessary code and USB debug counter Clicking Toggle IONI USB Configuration -button does not reset all motor faults, only the Simplemotion faults. Known issues: Estimated torque output calculation is stll likely wrong. When using high forces and having the reconstruction filter at high value, the wheel might go numb and give a feeling of saturated forces. This is being investigated.
October 13th, 2017	0.8.3 / 0.8.3	10601	Public beta release	[4]	Changes and fixes: Serious USB issue is fixed. Replies to USB control requests weren't getting sent to PC if SimuCUBE was already in the process of sending a normal HID report. This caused crashes in games. Known issues: Estimated torque output calculation is most likely wrong. When using high forces and having the reconstruction filter at high value, the wheel might go numb and give a feeling of saturated forces. This is being investigated. Some filter settings do not seem get applied with some user actions.
October 8th, 2017	0.8.2 / 0.8.2	10601	Public beta release	[5]	Notes: Unfortunately, this version will clear all profile settings. Please take note of all your settings. Note: Updates do not have effect on the parameters that are stored on IONI drive, so no new drc configuration files should be needed. Precautions have been made to minimize this being required in the future. New features: Profiles can be saved into simucubeprofiles.ini file and imported from that file. Imported profiles are added, they will not overwrite user's profiles. Feature has an indicator for successful loading and saving. Force scaling (in percentage) is done by setting MMC on IONI drive instead of scaling the torque that goes to drive. This increases the fidelity. NOTE: To change maximum MMC, upload a new DRC file with new setting using the motor configuration wizard, or use Granity to set new MMC. Motor configuration wizard has a field for Motor Torque Constant. If it is set, configuration tool assumes 48 V power supply, reads motor resistance from current IONI configuration, and shows maximum torque value in the UI. Changes and fixes: Analog button debounce time has been increased from 10 ms to 20 ms. Setting for this might be added in the future. Analog axis settings import/export now has an indicator for success/failure. Analog axis averaging has been changed from average of last 32 values to average of last 32 values but disregarding 4 highest and 4 lowest values to improve signal quality. Steering centering offset value was not saved correctly if the index point was sufficiently off-center (more than 65535 counts offset). This was evident on high-resolution encoders. Maximum number of profiles has been reduced to 500. Game-induced torque could easily overcome the bumbstop effect's torque, making the wheel spin uncontrollably. This has been fixed. Damping filter was being sent to IONI with setting of 0.0 % if game set a damping effect. This was unintended, and has been changed for this version. On-the-fly changing damping, inertia and friction effects are not being done currently. Improved resiliency against non-communicating IONI drives. This could happen if, for whatever reason, the SMO Bus Address Offset was other than 0, and the drive was still functional when using MMos firmware. Improved/fixed some subdialogs to work better with high-DPI displays or when display has a custom scaling factor. Enabling IONI USB communication mode does not cause a SimpleMotion error / Fault in the IONI drive anymore. Known issues: USB-related game crash issues Estimated torque output calculation is most likely wrong.
September 19th, 2017	0.7.1 / 0.7.5	10601	Public beta release	[6]	Changes and fixes: Some profile settings were being set to default when running the firmware update wizard Ioni filter parameters are no longer being read to the active profile, overwriting the profile values, when running the motor configuration wizard Changed TBW to 1000Hz as default for all new profiles and also for the default read-only profile. Minor text changes in firmware update wizard
	0.7.0 / 0.7.3	10601	Closed beta release	not public	New features: Profile can be copied Bug fixes: Profile name did not get applied and saved if only profile name was edited Configuration tool crashed if user canceled or finished the Firmware Update wizard
	0.7.0	10601	Closed beta release	not public	New features: Working digital button inputs Profile management Analog settings .ini-file import/export Bug fixes: Settings change by some amount at saving or load from IONI drive.
	<0.7.0		Closed beta release(s)	not public	No change history for these early firmware releases.

IONI firmware

As SimuCUBE requires an IONI Servo & Stepper Drive, it is recommended to keep the on-board IONI firmware at latest release. SimuCUBE firmware has the IONI firmware bundled in, and the IONI firmware will be automatically updated if the current IONI firmware on the drive is too old. For manual firmware updates, see IONI firmware releases and Granity user guide/Uploading a firmware.
