无法通过I2S读取ES8311的音频数据

发布于 2023-01-06 09:39:36

使用WM-W800-SDK-202207-V1.00.08工程。

对ES8311使用I2C进行配置后,无法使用I2S进行读取,读取过程一直等待。不知道问题出现在哪里,是ES8311和I2S的配置错误,还是我使用方式有误。

代码如下:

#ifndef __I2C_H__
#define __I2C_H__

#include "wm_gpio.h"
#include "wm_gpio_afsel.h"
#include "wm_i2c.h"

#define I2C_FREQ (100 * 1000)

#define I2C_SCL WM_IO_PA_01 // 控制线
#define I2C_SDA WM_IO_PA_04 // 数据线

/**
 * @brief I2C 初始化
 */
static inline void i2c_init(void)
{
    // 配置引脚
    wm_i2c_scl_config(I2C_SCL);
    wm_i2c_sda_config(I2C_SDA);
    // 设置时钟频率
    tls_i2c_init(I2C_FREQ);
}

#endif

#define __I2S_H__

    tls_pwm_out_mode_config(channel, WM_PWM_OUT_MODE_INDPT);

推荐参考这个SDK,里面有现成的codec驱动代码。http://ask.winnermicro.com/article/74.html
