RE: 是否可以 3顆 18650 並聯輸出電到 typeC USB 充電孔?posted in Hardware
@tonyone0902 如下图所示,板子的BOTTOM面有测试点,可以焊接外部电源。

机器本身不具备电量侦测功能,可以外加库仑计通过I2C接口。 -

@tonyone0902 最低输入电压5V,所以并联是不行的,串联12V从TYPEC输入没有问题。

RE: 官网源码不支持树莓派官方最新摄像头IMX477R和IMX708posted in Peripheral
@xingzhan2012 摄像头的调试周期会比较长,做AI部分对摄像头像素要求不会太高,可以考虑先使用USB接口的摄像头模组。

RE: Cool Pi 4B 如何使用GPIO啊,树莓派的HQ Camera如何使用呢?posted in Ubuntu
@xingzhan2012 摄像头可以使用gstreamer。默认的镜像里边已经支持。
USB摄像头预览,参数根据自己设备的情况修改:gst-launch-1.0 v4l2src device=/dev/video20 ! image/jpeg, width=1920, height=1080, framerate=25/1 ! jpegparse ! mppjpegdec ! kmssink plane-id=88摄像头编码:
gst-launch-1.0 v4l2src device=/dev/video11 ! video/x-raw,format=NV12 ! mpph264enc ! h264parse ! filesink location=1.h264 -e注意:默认的mipi摄像头对应的video11节点,USB摄像头对应的video20.

RE: 双4K usb摄像头posted in Hardware
@jugg QT调用gstreamer的例子网上有很多,QT官方也有教程。先尝试一下。注意KMSSINK虽然性能比较好,但是会独占图层。开发的时候注意下。
