停止Camera转到Audio会出现I2S错误

coollofty commented 3 years ago

我使用如下代码停止了Camera： cam_deinit(); i2s_driver_uninstall(I2S_NUM_0); i2c_driver_delete(I2C_NUM_0);

然后再调用（代码来自web_tts工程的app_main.c）： ESP_ERROR_CHECK(i2c_bus_init()); ESP_ERROR_CHECK(audio_init());

就会出错

错误是：E (27020) I2S: Register I2S Interrupt error

如果不对摄像头进行初始化，一上来直接调用音频的代码，是没有问题的。同样，如果先初始化音频，再销毁，然后再使用摄像头，cam_take函数将永远不会返回。

I got exactly the same error in i2s_set_pin, same LoadProhibited, same EXCVADDR. I didn't figure out why, but when I moved the task from core 0 to core 1, the error went away.

edit: I was using a component that set an interrupt routine. The problem went away when I disabled this component.
