Solution 38058: TI-Innovator™ Hub Vibration Motor runs when you plug it into OUT3.
Why does the TI-Innovator Hub Vibration Motor runs when you plug it into OUT3?
The vibration motor will start vibrating as soon as it is plugged into OUT 3. This is caused because when connected to OUT 3 the motor comes under software control after a ‘CONNECT’ command is executed.
When using the motor with OUT 1 and OUT 2 this does not occur and the motor remains OFF till it is enabled through a “SET” command.
If this behavior is an issue, use vibration motor with OUT 1 or OUT 2 ports.
