研发之路第五条———PWM的配置与输出其二（NRF52832筋膜枪研发）

鄙人才疏学浅，如有看不入眼的代码和见解，烦请各位指教。

回放重启的配置

我们先看一下回放重启如何配置。

static nrf_drv_pwm_t m_pwm0 = NRF_DRV_PWM_INSTANCE(0);
static nrf_drv_pwm_t m_pwm1 = NRF_DRV_PWM_INSTANCE(1);
static nrf_drv_pwm_t m_pwm2 = NRF_DRV_PWM_INSTANCE(2);

// This is for tracking PWM instances being used, so we can unintialize only
// the relevant ones when switching from one demo to another.
#define USED_PWM(idx) (1UL << idx)
static uint8_t m_used = 0;


static uint16_t c
