Hello!
I’m new to simpleFOC and i was following the Getting Started Guide. I sucessfully tested the driver, but when i got to the open loop example (BLDC motor 3PWM), i couldnt get the motor to spin. However when i added the “motor.loopFOC();” to the loop function it worked perfectly. I would like to report this so people can save some time when first starting with SimpleFOC, given that this is an error and i didnt misunderstand anything 🙂

You’re absolutely right. I’ll update it asap!
Thanks for pointing this out 🙂
EDIT:
`motor.loopFOC()` is mandatory for all applications, I juut forgot to update it at a couple of locations.
The docs should be up to date now.
However, I’ve just noticed that I did not update the openloop examples in the library.
They are up to date in the master branch. Here is the link for those having issues:

motor.loopFOC() was not required previously for Open Loop velocity control. only closed loop. has that changed with the new version?

`loopFOC` is not mandatory because we now can choose between all the torque control strategies for the open-loop control.
- voltage (the only one possible till v2.4.0)
- estimated current
- foc current
- dc current
And loopFOC is the one doing the torque control.

Ohh! Interesting. I definitely need to try out 2.4.0 now. I will update my device this weekend.
