Just want to say, Dec. 13 is 1 year since the motor controller was started, and it was snowing then, and it's snowing outside right now! ya! I was sliding all over the place outside on the road tonight. It was pretty much awesome.

Happy B-day to the Open ReVolt...

BTW, from (trying to) read this monster thread, I have gathered that the ReVolt has gotten a few more features (in software atleast) than is listed in the Wiki... Wouldn't it be time to update the list of specs?

I think its about stability and testing. All the features haven't been tested like all the others until rev. 2C, even though they seem to work for some individuals. Somebody correct me if I'm wrong. I was wondering about the same thing before.

That's what I asked pages ago - basically a status update, as well as what new features are missing, but alas nobody seemed to reply.

I also suggested that an external input from a BMS to cut power might be in order. Not sure if this has been discussed or not, I haven' been following the thread as closely due to work.

Here's Fran's code versions:
Sorry you guys. Here's a code improvement breakdown:

version 0.1 - first version tested
version 0.2 - added PW (PWM) to realtime data
version 0.3 - added thermal cutback code (to be checked by Paul)
version 0.4 - added continous check of vref below 2V
version 0.5 - declared some variables volatile to enforce execution within bounds of cli() and sei()
version 0.6 - make ocr1a_lpf time constant longer - V0.5 oscillates if Kp,Ki are low (slow PI loop)
version 0.7 - fixed stupid bug in config_pi() that caused Joe's problems (thanks Joe)
version 0.8 - high pedal lockout added but not yet tested
version 0.9 - store mutiple copies of configuration in EE prom (not yet tested)
version 0.10 - code size reduction, correct thermal cutback starting point, selectable pwm low pass filter
version 1.0 - in pi_loop() added cli() and sei() around update of OCR1A, added cli() after pi_loop
version 1.1 - added battery amps and battery amp hour calculations (not yet tested)
version 1.2 - added motor overspeed logic (experimental and not yet tested)
version 1.3 - added battery amps limit (not yet tested) and changed motor overspeed parameters to 4 digit
version 1.4 - new 8KHz PWM compile to option, added battery_amps_limit, spare, and crc, default_config PROGMEM
version 1.5 - fixed ocr1a_lpf calculation - so battery amps limit should now work, added "restart" command

Mark,

The reason there is no firmware for revision D in the wiki is that I haven't written it yet. I've just got a working hardware prototype, so I will be doing that soon ( a week or two).

Don
Hi Don,

Is there any news on the release of firmware for the revision D controller ?

- Mark

Hey Royal! Thank you!!! Want to know something funny? Sunday is my birthday too! Man, I hope I feel better soon. I have the flu. It came out of nowhere. I thought I was fine this morning and then by 11am, I was throwing up! is that too much info? As soon as I feel better, I have a kit that was returned to me that I'm checking out and fixing up and am going to test Fran's new code, with version 1.5 and 1.6. ya! My goodness, I only drank water today, and I'm not even hungry. I know someone that should hear about this excellent weight loss program!
