The V3.1 Cycle Analyst firmware that went through various Beta releases last year is getting so ready for prime time. In addition to the digital aux input buttons, factory resets, enhanced ebrake and regen features, and display screen customizations, there have been other updates including:

  • Additional PAS modes, supporting cadence control so that you can have the PAS output power or throttle voltages vary with your pedal cadence. There is even a PAS mode for electric assist rowbikes with reciprocating PAS sensors. 
  • The ability to automatically return to the main display after a given time and have the Aux change pop-up display just in the custom views tab.
  • An increase in the output data logging frequency to 10Hz for even better dynamic analysis of vehicle performance
  • Pre-loaded settings for all the common torque sensors offered by Grin.
  • Ability to copy all settings one set of presets from another.
  • A switch to watt-hours rather than amp-hours as the primary battery lifetime usage, for a more universal comparison of total energy expenditure.

The companion software setup utility has also gone through numerous improvements with the 1.53 release. You can now upgrade your CA from a 3.0 to 3.1 firmware and it will preserve almost all of your settings and usage statistics, so there's no need to record and re-enter all your values. There are detailed tooltips over each of the parameters to help you understand their functions, and a comprehensive help menu as well. And to top it off, there is now a single button you can click to fetch the latest firmware from our servers, making any future update process seamless as well.

CA Setup Utility 1.53 Improvements

The most recent firmware build is CA3.1Beta21, and well be giving it 1 week of wider beta testing before we make this the final release CA3.10 version. If you are keen to try this and upgrade from a CA3.0 device but don't have the necessary cables, we have both the USB->TTL programming cable as well as the handy up-down digi-aux buttons available from Amazon.com for easy US shipping.

We'd like once again to thank endless-sphere user Teklektik for his tireless efforts at instilling structure and discipline in the Cycle Analyst development and getting the firmware to deliver on our original vision, and to our software team and co-op students who produced the matching CA Setup Utility suite.
