VEYE MIPI 290/327 for Jetson Nano/zh (view source)
Revision as of 13:15, 17 March 2020
, 13:15, 17 March 2020→概述
VEYE-MIPI-290/327是星光级内置ISP的摄像头模组，输出为MIPI-CSI2接口UYVY流模式。对于图像效果参数，我们并没有采用V4L2接口实现，而是采用了Shell脚本直接控制摄像头模组。

Jetson Nano的CSI2接口与树莓派的兼容，因此[[Mini Adapter Board/zh|Mini Adapter Board]]与[[Adapter Board for Raspberry Pi/zh|Adapter Board]]都可以使用。此外，需要额外的5V供电。
