First, we need to determine your motor's stator and rotor inductance, and a stator coil resistance. In my case, it works fine to just use the same rotor inductance as stator inductance. To figure out the stator inductance, we have to run a test and measure the offset of 2 waveforms. I'll set it up, and make sure it's working on my end before sending it over to you so you don't get stuck with a crappy hex file.
Looking forward to it! Once the sensorless code is spinning the motor, I've GOT to get some video posted!
