[参考译文] TLV320AIC3204：TLV320AIC3204：TLV320AIC3204如何将数据传输到音频处理芯片？

尊敬的 Luo：

1.这是可能的,但有轻微的修正。 仅 I2C 用于控制器件设置。 I2S 用于传输音频数据。

2.是的,这是可能的。 方法是将 DAC 输入设置为左/右数字数据、将 DAC 输出路由至耳机、并为耳机驱动器上电。 请参阅以下脚本作为参考。

# High Performance Stereo Playback
# ---------------------------------------------
# PowerTune mode PTM_P3 is used for high
# performance 16-bit audio. For PTM_P4,
# an external audio interface that provides
# 20-bit audio is required.
#
# For normal USB Audio, no hardware change
# is required.
#
# If using an external interface, SW2.4 and
# SW2.5 of the USB-ModEVM must be set to
# HI and clocks can be connected to J14 of
# the USB-ModEVM.
#
# Audio is routed to both headphone and
# line outputs.
