The boot loader uses the internal oscillator you want to write a bootloader based on template? Or your app? The app you can of course modify to 25 MHz. It's just important that the core frequency remains at 72 MHz because CAN relies on it. But as far as I remember from the Olimex proto board that is...

Nice, congratulations

Yes. Just have to pay attention to use the correct UART and CAN perhaps with the correct pin remap

Your fix just for DC? Does the AC current values drop to zero too? AC values are not session based but continuously updated. E.g. EvseAcCurrentLimit will drop to 0 instantly when PWM goes below 8% or above 97% The PP resistance measurement is disturbed via the path R64 (1k to 12V), D21, PP_WAKE, JP...

Because we forgot

This should fix it but haven't tested https://github.com/uhi22/ccs32clara/pull/39

that's normal, unfortunately. It is slightly filtered and more importantly it is filtered even more before entering the control loop

Got the modules on the table now. So far I've established that module 2 and 5 had a shorted mosfet on channel 0. That's how they became hot and that's why they only displayed something meaningful on the first channel because all the others were shorted out. On module #3 the mosfets seem fine but it ...

It's random. They just need to have the same sign (ocurlim and ilXgain). In FOC it is relevant in sine not

I don't know, I'm thinking it's because the anti-pattern doesn't fit perfectly so there is still some of the original oscillation left. Or do you mean there is a hull curve around the HF pattern? On a side node the project now build again and we have binaries: https://github.com/jsphuebner/stm32-sin...

Which version software? The more recent ones take 1 as a multiplier for unity gain, no longer 32

You can map idcmin and idcmax to receive via CAN. On the newer web interface this is possible via gui, on the older on you'll need a custom command like
But of course the same is possible with SDO

Rigged up a first cut of my hopefully next 12V battery. Those a 60 Ah NMC cells weighing about 1 kg each. I put some plastic in between them because you shouldn't trust that thin protection foil for electrical isolation. Currently charging it with a cheesy "2A" buck converter that works al...

It's quite individual with wifi reception. Yes it is generally poor if the module sits in a metal enclosure but it can still be workable. For example in the Nissan inverter it is usable in Tesla inverters it is not. In my VW ECU case it tripped my annoyance threshold and I mounted it outside, bringi...

yes https://github.com/jsphuebner/stm32-CAN ... s/tag/v1.3

That sounds worrying to me with my PP only wakeup. Kempower isn't common around here. Have you measured their PP with a multimeter?

So I'm doing some experiments on this. Here we have the amplitude of il2 about 20% lower than il1. image.png This also creates a 2nd order harmonic but it is sinusoidal. Same result when il1 has lower amplitude than il2. Here we have a periodic disturbance on just il1: image.png This causes dips in ...

Yes try that and if it doesn't help set dirmode=DefaultForward

Keep the other parameters as instructed until you succeed.

So to my dismay tmphsmax is still at 85°C. I told you to set it to 110 to disable the derating. But maybe that isn't the problem. In cmd-T.txt din_forward=0 so no direction selected. In cmd-T2.txt it is 1, so forward selected. Could it be that your forward signal is unstable? This would explain why ...

First test drive with wife, but only 17 km she says she can't hear the whining anymore!

In two weeks we will drive a longer distance, lets see how it goes!

I only marginally understand what is being discussed here. Is this problem only with the EM57 motor or with all permanent magnet motors and are sine wave motors not affected? From the papers I've read this seems present in all PM motors. Is this noise issue just new or was it ever present or did it...

THROTTLE1 means the throttle calibration is off. Have you read and done this? https://openinverter.org/forum/viewtopic.php?t=5075 The 5.35.R firmware requires it. You can also revert to 5.32 to skip this for now EDIT: it's also helpful if you try to pull a json dump in the respective situation. Like...

yes

5.35 no longer accepts pedals that max out the ADC dynamic range. So you have to put a 3-10k resistor inline with the pedal and recalibrate.

Asymmetric behaviour is usually down to wrong pinswap: viewtopic.php?p=63807#p63807

I did a first cut of the firmware: https://github.com/jsphuebner/stm32-sine/tree/anticogging I'm not yet happy with the result: Screenshot 2024-09-30 at 16-42-10 Huebner Inverter Management Console.png You can see it creates a good correction value but the oscillation is still there. Not sure if the...

I take it that blue is id and red is il1? (Include the labels in your screenshot) So same situation like mine, unsurprisingly. Are you running the EM57 as well? I'm trying to write some code today that tries to quantize the cogging in phase and amplitude and then counteract with ud in feed-forward f...
