EB-SS928 UVC调试-uv-9000s怎么用

2023-04-20 10:32:02

1，查看当前板子硬件图

找到J11对应的原理图

通过硬件手册确定复用关系

查看相关寄存器功能描述

USB3.0-HOST 0x1030_0000

USB3.0-DRD 0x1032_0000

Offset Address: 0xC110

PERI_USB3_GCTL 2’b10 Device 2，确定编译配置文件

EB-SS928 UVC调试-uv-9000s怎么用5 以及menuconfig 的UVC配置项是否有开

按<手册UAC开发参考.pdf> 配置并编译好系统。

3，修改系统配置文件

vi /etc/profile

export VID=“0x1234”export PID=“0x0001”export MANUFACTURER=“Xxxx”export PRODUCT=“Camera”export SERIALNUMBER=“12345678”export YUV=“360p”export MJPEG=“360p 720p 1080p”export H264=“360p 720p 1080p” 4,执行脚本

ConfigUVC.sh

创建/dev/video0文件节点

5，执行sample_uvc6，使用Win10自带软件或AMCap
