ESP32-S3-Korvo-2 V3.0 es8311 无法播放声音

[hexianren]

我用 examples文件夹 i2s_es8311 在ESP32-S3-Korvo-2 V3.0开发板上播放没有声音，配置如下：。pipeline_http_select_decoder例子是可以播放的，哪位老师有时间帮忙看看哈

您好, 代码中存在两个需要修改的地方.

1. 修改 I2S 的 data_in 和 data_out 配置

Code: Select all

/* I2S port and GPIOs */
#define I2S_NUM         (0)
#define I2S_MCK_IO      (GPIO_NUM_16)
#define I2S_BCK_IO      (GPIO_NUM_9)
#define I2S_WS_IO       (GPIO_NUM_45)
#define I2S_DO_IO       (GPIO_NUM_8)
#define I2S_DI_IO       (GPIO_NUM_10)

2. 在初始化 es8311 后, 使能 ESP32-S3-Korvo-2 开发板上的 PA
您可参考硬件设计: https://espressif-docs.readthedocs-host ... rvo-2.html
参考代码:

Code: Select all

gpio_config_t io_conf;
memset(&io_conf, 0, sizeof(io_conf));
io_conf.mode = GPIO_MODE_OUTPUT;
io_conf.pin_bit_mask = BIT64(GPIO_NUM_48);
io_conf.pull_down_en = 0;
io_conf.pull_up_en = 0;
gpio_config(&io_conf);
gpio_set_level(GPIO_NUM_48, 1);
