欧拉派海鸥系列的驱动测试程序使用说明

1. 环境准备

   参考 欧拉派海鸥系列镜像构建与使用 准备开发板环境。

2. 音频测试

   测试前将带麦克风的耳机接入开发板音频输入输出接口。

   export LD_LIBRARY_PATH=/usr/lib
   cd /root/device/sample
   ./audio_sample <index>
   index and its function list below
     0:  start AI to AO loop
     1:  send audio frame to AENC channel from AI, save them
     2:  read audio stream from file, decode and send AO
     3:  read audio stream from Mydream44100.aac file, decode and send AO
     4:  start AI(VQE process), then send to AO
   

3. hdmi测试

   测试前将显示器和开发板用HDMI2.0线接好。

   export LD_LIBRARY_PATH=/usr/lib
   cd /root/device/sample
   ./audio_hdmi
   hdmi_cmd:
      help                 list all command we provide
      q                    quit sample test
      hdmi_hdmi_force      force to hdmi output
      hdmi_dvi_force       force to enter dvi output mode
      hdmi_deepcolor       set video deepcolor mode
