Ahh, I see!

Okay, I will change that in the firmware to avoid negative values.

The negative current values are real, they're coming from the CC.
On the other hand I never saw negative values before and I am sure that also you will not see them in real flights.
The negative current values are due to that on/off that you have practiced and with no load.

Yes, I know it Normal and not normal ;D But that is the reason of my peaks in current on receiver display.

2-complement, integer to unsigned integer. Quite normal.

OK
Oh, one thing - In HoTT Manager values are not negative...values are positive - 6533,5A

Yep, I see now, 2-pole in config.
Set to your motor's pole number and also the gear ratio. The latter is no problem because we're logging TWO speeds, rpmMOTOR AND rpmROTOR.

Motor RPM is high because it works without propeler (2600kV so 50-53k is OK) I don want to set gear ratio. For me motor RPM is more important. Motor of course is 2 poles
There are a lot of negative values of Imot I can see it now in Graupner HoTT Manager.

Looking much better so far, I cannot see any hazard pointing on noise.

Only:

- RPM is going crazy during spool-up. Looks like it comes from the CC itself.

- RPM motor is a little high.. What pole number is setup by JLC?
(Please attach your CONFIG.txt.)

- The gear ratio isn't set yet in JLC (-> rpmUni - head speed).

- Capacity is looking very strange because of some negative(!) records for Imot. (Think I should force to unsigned integer.)
(Because of these short jumps in throttle negative current values appeared in between (pulse distance <500us).)

No, there is no step, nowhere, as well as not for Imot.
The CC will have a resolution (discrete pulse distance) of course.
Everything below 10 amps is rather inaccurate as it comes from the CC.

There is some problem with temp sensor on my Castle - as I see. I have to look for others logs. Today datas are more reliable. I don't knoe why
Current is logged by JLog with 1A step? On transmiter display there are still peeks of current >500A. Conections are without any loops.

Well.., data from a CC is not very reliable, at least the temperature not.

Well, probably afeter switching on Link Live my Castle is crazy now. Data are more or les the same as from JLOG Strange. After that there were no problems with data. I will test it tommorow or day after tommorow. If will be no rain I will fly.

I will se what I have in Castle logs

Hmm...

Up to 17% of PWM, 70 amps peak by fast transition of PWM 0-->17%.

44A at 5% PWM..

A bit high, isn't it?
And if I look at temperature (°C), -19, -22, -26, .... can't be.

What do you find in the file "CCinfo.txt", what in "version.txt"?

It seems to me that the pulse length calibration did not work for any reason..
(The time base of both devices will differ. So at least one of the pulses of the CC (data type) is taken as calibration item.)

Thanks for reply. Now it is clear form me I will rebiuld my model to test JLog. GAM will wait for its better time.

My short log file is included.
