First of all I want to thank sskaug for all his work!!!!

I have an old Walkera esc laying around and wanted to put it to some good use. Thanks to all the details in this thread I was able to flash it with the the hex file sskaug provided. After that I tested the setup with a beta fpv 19KV motor. So when I apply current I hear the three arming beeps. Than I arm the setup with some generated pwm signals(1kHz). After arming I can spin up the motor, but I'm not able to control the speed. No matte what duty cycle I put into my code the motor keeps spinning with the same speed.
I know that I resurrect a dead thread but maybe some of the old guys could help me with that problem?

Cheers

Default Walkera ESC + 19500KV Motor

Hello, first of all I want to thank sskaug for all t he work he put into the blheli stuff! You really elevate the game for all of us heli lovers

I'm fully new to this and while reading about blheli I decided that I also want an open esc. Because I had a walkera esc laying around(The upper one from the photo) I wanted to give it a try. So I've flashed V3 of sskaug's bl software. It works and I can arm the Motor, but sadly I can not control the speed. When I flash V1 I can control the speed but the motor gets so hot that it burns. I use the setup with a Betafpv 19500 KV motor with 12 poles.
Could anybody help me get this setup to work please?
