There is already testcode available here: https://github.com/bitdump/BLHeli/tree/master/BLHeli_32%20ARM/Half%20pwm%20low%20frequency%20testcode This code does not go down to 16k. What it does is to use half the pwm freq low of what the Suite...

Hi Jacques Thank you for this detailed report, we will surely investigate it. Some questions: - What are the blue and yellow traces above? - Is it the erpm frequency...

Thanks again for the info. We will surely dig into this. Would you be willing to test experimental codes to help diagnose this? Which exact code does your ESC use?

Great, so now I have posted three testcodes: https://github.com/bitdump/BLHeli/tree/master/BLHeli_32%20ARM/Noisy%20erpm%20data%20testcode All will show up as rev32.75, the difference between them are given in the hex file names. There is one 32.7...

Actually, thanks to your very good plots, I'm pretty sure I have nailed the cause of the large spikes. So I believe that the "32P8_NO_FASTERPMUPDATE" testcode does not have spikes....

To summarize the numbers: 32P8 4000 rpm: [600] 32P8_NO 4000 rpm: [200] 32P7 4000 rpm: [150] 32P8 15000 rpm: [2500] 32P8_NO 15000 rpm: [2500] 32P7 15000 rpm: [2500] Are the...

Again, thank you for the test data, it shows exact correlation with expectations. The spikes will only be present for RPMs below approximately 5600 (14P motor). It would be great...

Thank you again for testing. So from these, I'd say that the severe spikes are gone, which should make it worth publishing this fix for all targets. We will also...
