Faster atan2 #329

Closed Candas1 closed 11 months ago

Candas1 commented 11 months ago

Shamelessly copied, even the credits (see the comments)

Before: RAM: [= ] 9.0% (used 4444 bytes from 49152 bytes) Flash: [=== ] 26.9% (used 70592 bytes from 262144 bytes)

up to 48us

After: RAM: [= ] 9.0% (used 4444 bytes from 49152 bytes) Flash: [=== ] 26.7% (used 69912 bytes from 262144 bytes)

up to 28us

Reduces memory usage and almost twice as fast on a STM32F1 It's not used in the SVPWM anymore but can be useful for other features. I am using it in the flux observer sensor.

Hmmm...

That doesn't really look like it has to do with your change...

So I will merge this, it is compiling for all other platforms except ESP32.
