看下同时播放两个的代码如何实现的, 依葫芦画瓢, 改成三个同时播放.

@uuuuid

命令行没有问题，后台启动mpv：

mpv --quiet --no-terminal --no-video --idle=yes --term-status-msg= --input-ipc-server=/tmp/mpvsocket

加入歌单：

echo '{ "command": ["loadfile", "./music/a1.wav", "append"] }' | socat - /tmp/mpvsocket

设置当前播放音乐：

echo '{ "command": ["set_property", "playlist-pos", 0] }' | socat - /tmp/mpvsocket

本来还想用 F1C200s把楼主的demo跑起来, 发现mpv播放wav文件cpu占用率90%+

没法玩了．

请问什么逻辑分析仪可以抓DSI数据？

@chunzhang

奇怪了，我这里 D1 SPI NAND fastboot 直接失败， 啥也动不了。

v2.0 果然修复了这个问题。

驱动也没有，洗洗睡吧：

$ grep "allwinner," -r /opt/t113/tina/kernel/linux-5.4/drivers/ |grep "can"

T113 Datasheet： T113-S3_Datasheet_V1.2.pdf

解压后只有一个 .repo 文件夹，需要用 repo sync -l 命令从本地仓库恢复文件。

T133和 R528 都是双核A7，内置DDR3 128M，只是封装有点差异。

手册上面确实只看到了功能，并没有引脚。

没玩过，帮顶一吓
