intr_alloc_flags:用于分配中断的标志,使用这个函数会占用LEDC模块的中断;esp_err_t:返回值,ESP_OK表示成功。 2.6、LEDC渐变步长 代码语言:javascript 代码运行次数:0 运行 AI代码解释 esp_err_tledc_set_fade_with_step(ledc_mode_t speed_mode,ledc_channel_t channel,uint32_t target_duty,uint32_t scale...
I tried to enable the SPI slave interrupt using esp_intr_enable_source(ETS_SPI2_INTR_SOURCE) and whenever any byte I receive from the master, control goes to receive ISR and do some task for that I am using esp_intr_alloc(ETS_SPI2_INTR_SOURCE, ESP_INTR_FLAG_SHARED, spi_slave_isr_...

esp_intr_alloc(ETS_I2S0_INTR_SOURCE, ESP_INTR_FLAG_LEVEL1, i2s_in_isr, NULL, NULL); } 注意事项 中断延迟:确保中断服务函数(ISR)尽可能简短,避免阻塞。复杂操作应放在任务(Task)中处理。 双缓冲区机制:通常需要多个 DMA 缓冲区交替使用,以实现连续数据流。
