Did not change anything. I tried the throttle only code once again and now it does not work either. Sorry, then I can't help any more. I am at the end of my rope at this point. :confused: regards stancecoke Any help with the gazelle branch error: C:\BMSBattery_S_controllers_firmware-Gazelle>PATH = ...

Tested and the problem came back OK, so we have to skip all the condition checks first. Replace lines 205 -324 with uint32_current_target = ui16_current_cal_b; // reset target to zero controll_state_temp = 0; ui8_temp = ui8_assist_percent_actual; if ((ui16_aca_flags & DYNAMIC_ASSIST_LEVEL) == D...

What to do next to get the PAS working also? untested suggestion, replace lines 205 - 291 from the recent Master with: uint32_current_target = ui16_current_cal_b; // reset target to zero controll_state_temp = 0; ui8_temp = ui8_assist_percent_actual; if ((ui16_aca_flags & DYNAMIC_ASSIST_LEVEL) =...

Valopallo

you could try to replace all the lines 206-324 by just this two lines: uint32_current_target =ui16_sum_throttle + ui16_current_cal_b; ui32_dutycycle = PI_control(ui16_BatteryCurrent, uint32_current_target,uint_PWM_Enable); This just takes the throttle signal for controlling the current. You can do ...

you could try to replace all the lines 206-324 by just this two lines: --- So of course be aware, that this suggested code modification is not tested at all and there is a risk to burn your system... regards stancecoke Well that's quite risky. I might try other branches before that operation. I did...

So I basically just copy/ paste /replace everything starting from line 211 of ACAsetpoint.c No, not if you want to use PAS / Throttle. I have only optimized the part for the torquesensor data processing. There is the basic PAS calculation in lines 220-232 that has to be changed and then later, depe...

What parameter changes could I try to fix this? This has nothing to do with parameter settings. It's just a processor overload. As written several times before, you need to replace all the float- and division operations in Xnyles code with integers and right shifts. We have done this for the branch...

My 2wd project has been running nicely the whole summer. I modded my s06s controllers so they transfer the heat of the big resistor and the lm317 and I have been riding with the factory firmware on both of them at 58.8V max without any problems. Without display I wasn't able to use PAS so I used onl...

Hello. I want to share my 2WD bike's KT24/36-SVP -controller case mod and my frame casing with alarm. IMG_20210510_181938.jpg I drilled a hole to the side of the casing, sealed the lm317 with kapton tape and the big resistor with heat resistant tubing from touching the screw and clamp.

I think you are right, the walkassist seems to be operating by default when I turn on the controller,

Your undervoltage is 67V!

Code: Select all

 67 x (256/200) = 85

I own a 18 fet KT labeled as 56V-90V, 50A max with a 16S (67V max) battery.

What could have changed with the code so drastically? You can see the history at github https://github.com/stancecoke/BMSBattery_S_controllers_firmware/commits/Master Thanks, I will try some of the older ones before the WALK_ASSIST changes because that would fit to my timeline of working master bra...

:warn: Has anyone else noticed that these latest problems with the firmware seem to have a pattern of correlation? Could the code have a bug that has been added with some new(<1 year) update? Symptoms seem to be; wheel spinning on it's own after throttle or pas. Burned mosfets. Overheating big resis...

Is there a temperature sensor on board No, and I think it wouldn't help, you have to measure directly on the critical components. I hope you really read the wiki and don't power your BT-module from the 5V rail of the controller :shock: No It's powered from the controller main as written there. Is t...

You can try to attach an additional heatsink to both parts.

Is there a temperature sensor on board and if so, how could I measure the controller temperature and test my cooling conditions?

If it still runs to the limit, there is something wrong with your phase current sensor... How can I test the sensor operation?

For those who want to optimize the waveform of their firmware, I've made a short tutorial. Once I figured this out life got better.

It seems I have to dig in to this deeply so I might as well learn how to properly use the firmware then. :D Hall Angle 4 : Defines the rotor angle assigned to Hall pattern 4.

I'd be inclined to use a lower Gain I value to start with, I find that the default of 0.2 gives quite an aggressive current ramp up which caused some issues on my setup.
