Detailed Description

PWM driver configuration structure.

Field Documentation

output_pins

uint32_t nrfx_pwm_config_t::output_pins[4]

Pin numbers for individual output channels (optional).

Use NRF_PWM_PIN_NOT_CONNECTED if a given output channel is not needed.

skip_gpio_cfg

bool nrfx_pwm_config_t::skip_gpio_cfg

Skip the GPIO configuration.

When this flag is set, the user is responsible for providing the proper configuration of the output pins, as the driver does not touch it at all.

skip_psel_cfg

bool nrfx_pwm_config_t::skip_psel_cfg

Skip pin selection configuration.

When set to true, the driver does not modify pin select registers in the peripheral. Those registers are supposed to be set up externally before the driver is initialized.

Note

When both GPIO configuration and pin selection are to be skipped, the structure fields that specify pins can be omitted, as they are ignored anyway.
