<![CDATA[Problems with Vibrator Motor Unit in uiflow]]>The Vibrator Motor Unit is still missing as a unit in uiFlow 1.2.3 and 1.4.5. The official sample code (https://docs.m5stack.com/#/en/unit/vibrator ) won't work with M5Stack fire. The program always crashes when I try to digitalWritePin 26. Any ideas how to get vibrator motor working?

Confirmed, the motor doesn't work properly.
I am sure that the unit only works as on or off as it only has an on/off transistor not a PWMable transistor.

I tried PWM on Pin 26, but it just crashes after running the program.

Even if I upload an empty flow with blank setup and loop functions, as soon as the M5Stack Fire boots, it tries to start the fan and crashes/reboots.

I'm testing on Port B. If I switch to Port A, that port has power all the time and turns the motor on full blast and I'm not able to control it.
