Re: Is rtems interrupt latency good enough for BLDC ESC? (on arm cortex-M or cortex-R)

Why do anyone even think of using an OS on such devices like the BLDC Motor driver? What's the point? Best regards. Peter Borisenko Awesome Technologies, Ltd. http://awsmtek.com +66826684211 On Mon, Sep 5, 2022 at 9:07 PM Sebastian Huber < sebastian.hu...@embedded-brains.de> wrote: > On 05/09/2

Just Curious, As for the title. I found an old article: https://docs.rtems.org/releases/rtemsdocs-4.6.0pre5/share/rtems/html/supplements/m68k/m68k00062.html, it said rtems's interrupt latency on MC68020 is The maximum period with interrupts disabled + 9 microseconds on 20Mhz. I see zephyr provid
