CONFIG_PWM_NRF5_SW¶

Nordic Semiconductor nRF5x series S/W PWM

Type: bool

Help¶

Enable driver to utilize PWM on the Nordic Semiconductor nRF5x series.

When used with HF timer it provides up to 3 pins, utilizing two PPI
channels per pin and one GPIOTE config per pin.

When used with RTC it provides up to 3 pins, utilizing three PPI
channels per pin and one GPIOTE config per pin.

Direct dependencies¶

SOC_FAMILY_NRF && PWM

(Includes any dependencies from ifs and menus.)

Default¶

y if !PWM_NRFX

Kconfig definition¶

At drivers/pwm/Kconfig.nrf5_sw:6

Included via Kconfig:8 → Kconfig.zephyr:42 → drivers/Kconfig:46 → drivers/pwm/Kconfig:36
