Detailed Description

Type of a PWM driver configuration structure.

Field Documentation

callback

pwmcallback_t PWMConfig::callback

Periodic callback pointer.

Note

This callback is invoked on PWM counter reset. If set to NULL then the callback is disabled.

channels

PWMChannelConfig PWMConfig::channels[PWM_CHANNELS]

Channels configurations.

Definition at line 180 of file hal_pwm_lld.h.

Referenced by pwm_lld_enable_channel(), and pwm_lld_serve_interrupt().

cr2

uint32_t PWMConfig::cr2

TIM CR2 register initialization data.

Note

The value of this field should normally be equal to zero.

Definition at line 187 of file hal_pwm_lld.h.

dier

uint32_t PWMConfig::dier

TIM DIER register initialization data.

Note

The value of this field should normally be equal to zero.

Only the DMA-related bits can be specified in this field.

Definition at line 193 of file hal_pwm_lld.h.

frequency

uint32_t PWMConfig::frequency

Timer clock in Hz.

Note

The low level can use assertions in order to catch invalid frequency specifications.

Definition at line 164 of file hal_pwm_lld.h.

Referenced by initWS2812(), and pwm_lld_start().

period

pwmcnt_t PWMConfig::period

PWM period in ticks.

Note

The low level can use assertions in order to catch invalid period specifications.
