The Cycle Analyst firmware version 2.1 is now officially released through the entire line of CA products. For most users there is little material difference, the trip amp-hours and distance can now go up to 1999 Ah or Km respectively, instead of 199, and the #poles variable for CA-DP devices now goes up to 99 instead of just 14 poles. But for those who like to tinker, there are extra pads now used for datalogging and external control of the speed or current limit, as explained on the first announcement last year. For those who are in and out familiar with microchip programming, the hex code is available for download here.
