What do you guys think of the following to keep things simple before it gets better: allow links to relevant posts in the wiki so that one gets kind of a box with wiki related posts, so that one does not have to go thru hunderds of pages with the risk of skipping the important posts by mistake... I...
by the way: i do not attempt to become a moderator here, but maybe it is better to make these kind of conversatiions in the other thread so that this here remains for the pure firmware discussion...so that we know why we have two threads altogether... To the group - what would be the most helpful w...
@ Cas I run today 0.15 with current ramp for lag. In my opinion the fix is solid even when starting in 8th gear. Previously the lag was 2s +. The power delivery is solid gold, bike is very responsive. I can hit 45km/h with 0.4 assist using 220w. Max, I couldnt find where to make the change so I jus...
Guys please help I am half way to work it was working fine now I turn off get assistance for a few seconds then no assistance and flashing 1 on the screen
Plenty of volts left and set minimum voltage.

Hi Casainho, I'm trying to implement this but it looks like you havent posted all your code ebike_app.c:277: error 20: Undefined identifier 'ui16_counter_adc_battery_current_ramp_up' ebike_app.c:279: error 20: Undefined identifier 'ui16_counter_adc_battery_current_ramp_up' ebike_app.c:280: error 20...
Casainho, I have run out of time today but will do the changes tomorrow and test the next day riding to work. So my friends and I always talk ebikes on our lunch time walk and we debated this same issue We thought the motor is going to apply power slowly but then needs to look at the cadence, if th...
hi casainho, i would suggest to use the wheelspeed as a factor for the ramp up. since when on speed faster ramp up is no such a problem for gears compared when wheelspeed is low. so not use a constant but a var multiplied with wheelspeed should give a quick response when its mostly needed, when on ...
Hi,casainho. when i downloaded the kt-lcd3 FW and stancecoke'FW successfully,the motor run normally, lcd3 canbe turned on,but not be turned off,and the UP/DOWN button is useless. the display showed that liked the picture and no change. Does not help if you duplicate your messages, posting them on d...

I implemented the current ramp but I could not test in detail because lack of time. But for my tests, most the lag is gone although there is still some that I think is because of torque sensor low pass filter on hardware. There is some tweaking that can be done, I put low conservative values and I d...
Yip it's the display no longer comes to life if it's switched off during use. So it's a problem of the LCD, not of our firmware. You can try to pimp your LCD, there seems to be the possibility to tune the shut off voltage, see here: https://endless-sphere.com/forums/viewtopic.php?t=94070&start=25#p...
With the new data on odometer field, it started to me a mess and so I did this improvements: - odometer data were group on some logic groups - now the odometer number os shown on wheel speed field, blinking for some seconds, everytime we change the odometer filed or subfield - now we can use combina...
let me say something though: i have programmed 5 assist levels. So, if i prefer in a given situation level 3 over level 2, it means that i want the higher power at that moment...so what i mean to say: if i limit myself to 200W (did i read from endless cadence that the middle/up button combo power v...
But I don´t like that approach having current controller on slow loop Perhaps you can do a similar log with you implementation, to see if there is any difference in the lag between current target and recent current. My log is with 50Hz slow loop frequency. I prefer to have current controller on fas...
With our experience, you don't need an extra control in the fast loop. Ah, I see. But I don´t like that approach having current controller on slow loop, I really prefer it on fast loop and on motor.c. Users are playing on ebike_app.c and that way are not making issues with the current controller, t...
1. we should implement a current ramp and not a duty_cycle ramp. Why don't you use a PI-controller for the battery current, like we do in the Kunteng project? With this you can adjust the response time very easily with the parameters Gain_P and Gain_I... I am not a big fan of PI controllers, I pref...
Just some testing on the inverse ramp factor to reduce lag UXVxzXzJDbc I really appreciate your work. After your notes and reports, I think I did learn a new things. First, I do not agree that we should just reduce the PWM_DUTY_CYCLE_RAMP_UP_INVERSE_STEP, as I believe it should be worst for the gea...
Assist level and start power boost now work as a factor of rider pedal human power I implemented it and it is so nice to look at LCD3 and see the motor exactly assist you, for instance, 200% of your generated pedal human power, if you did set the assist level to 2.0. On LCD3 odometer field you can ...
Vscope the lag also occurs without boost but that is not software related its purely due to the engine rpm catching up to your pedals, that is solved by ramping the motor up faster.. I have never used boost so not sure what this software issue is but I really dont know how you could ever program a ...
Rider pedal power show on LCD3 I implemented the code that calculates the rider torque/power/energy (in Watts), applied to the pedals. That value is now shown on LCD3, in odometer field. It also shows the pedal applied force (in Nm). I can see that my regular value is about 200W of pedal torque/pow...
Battery SOC using Watts/hour counter I improved the code that previous was reported to count 40% less than theoretical battery value. My battery pack of 4P14S 52V, 3600mA each cell, has a theoretical battery capacity of 4*3.6*52 = 748,8 Wh. Discharging my battery up to 36V (2.57V each cell), the LC...
Perhaps it might be useful to add a second magnet to the wheel This will double the frequency of the rotation reading. Obviously, the circumference of the correct wheel must be set. It is an idea that has already been used with the stock firmware That would be another extra part for users to buy, i...
BTW sometimes my speed sensor gives me weird values like 41km/hr and 64km/hr just pushing the bike around.. Anyone else have this ? Yes, often. When it happens to me it means that the magnet is passing a bit too close to the wheel speed sensor. But I've reverted back to the "stock" firmware and VLC...
maybe it would make sense to have up to 9 walk speeds. using up/down buttons when in walk mode sets the walkspeed. 0-9. On hills as I am being doing, I do not use assist level, I just keep assist level at 3 that gives me a good torque sensor/human power sensitivity and I just quick limit motor powe...
