The RPM sensor cannot be used on the CUAV v5 flight controller

The RPM sensor cannot be used on the CUAV v5 flight controller. The RPM sensor outputs a Hall signal. The configuration looks normal. The ground station keeps displaying rpm=3000. How to solve this problem? thanks

Is your rpm sensor connected to the A3 header? Please note that you need to set BRD_PWM_COUNT to be small enough; for example, for A3, you need to set BRD_PWM_COUNT=2 or less

我把BRD_PWM_COUNT设为2意味着就输出两路pwm,那还怎么控制舵机?我现在已经设为2了,但是rpm显示的-1
