board/bl706_iot/pinmux_config.h 中 CONFIG_GPIO20_FUNC、CONFIG_GPIO21_FUNC 选择 GPIO_FUN_PWM

board/bl706_iot/clock_config.h 中

  • BSP_PWM_CLOCK_SOURCE 选择 ROOT_CLOCK_SOURCE_32K_CLK,也可选择其他时钟源，用其他时钟源时应注意 case 中的设置要匹配
  • BSP_PWM_CLOCK_DIV 设置成 0

将两个通道分别接到 H 桥或半桥的两个通道


$ make APP=pwm_dc_motor BOARD=bl706_iot

正常运行后，GPIO20 和 GPIO21 引脚分别先后输出 PWM 波
