PWM interface parameters

Parameter

Description

Default

BSP_BOARD_IF_TIMx_STOP_MS

No-PWM timeout in ms

1500

BSP_BOARD_IF_TIMx_ARMING_VALID_TON

Number of valid PWM pulses (any duration) arming the board

10

BSP_BOARD_IF_TIMx_START_VALID_TON

Number of PWM pulses above minimum duration starting the
motor

10

BSP_BOARD_IF_TIMx_STOP_VALID_TON

Number of PWM pulses below minimum duration starting the
motor

1000

BSP_BOARD_IF_TIMx_MIN_SPEED_TON_US

Minimum pulse duration (corresponding to minimum speed) in
μs

1060

BSP_BOARD_IF_TIMx_MAX_SPEED_TON_US

Maximum pulse duration (corresponding to maximum speed) in
μs

2084

(1)

1. The value is calculated according to the following formula (BSP_BOARD_IF_TIMx_MIN2MAX_BITS = 10):

BSP_BOARD_IF_TIMx_MIN_SPEED_ 2

BSP_BOARD_IF_TIMx_MIN2MAX_BITS

. It is not possible to set an arbitrary

value: the range changes according to the BSP_BOARD_IF_TIMx_MIN2MAX_BITS parameter.
