|`WS2812_PWM_COMPLEMENTARY_OUTPUT`|*Not defined* |Whether the PWM output is complementary (`TIMx_CHyN`) |
?> Using a complementary timer output (`TIMx_CHyN`) is possible only for advanced-control timers (1, 8 and 20 on STM32), and the `STM32_PWM_USE_ADVANCED` option in `mcuconf.h` must be set to `TRUE`. Complementary outputs of general-purpose timers are not supported due to ChibiOS limitations.
