Khadas VIM3 don't shop the kernel with usbtmc and i2c mux driver, so I
rebuild kernel
inside fenix's docker.
The usbtmc and i2c mux are package as module, I load module automatic with systemd
by add usbtmc and i2c_mux_pca954x to /etc/modules-load.d/modules.conf.
Only one USB bus is exported in VIM3, I try to use orignal M.2 port as PCI-e port. I install ADT-Link's M.2 NVMe to PCIe X1 extender on Khadas M.2 extender board, then a PCIe Card(VIA VL805). The PCIe card is power by sperated 5V. But system only reconginze this card as USB2 bus. Why? May I also feed 12v pin. Once I mount USB3 device, system will reboot.
TODO: assign fixed camera path to specifical usb port. Device info could get
from udevadm info -a -p $(udevadm info -q path -n /dev/video0)
TODO: organize output information TODO: send command to power supply then release and return.
Build GUI in QT.
Reference:
- PyQtGraph library
- Assign fixed usb port name
- How to bind v4l2 USB cameras to the same device names even after reboot?
- Convert M.2 to PCI-e in VIM3

Before run SimpleBGC in khadas, please install librxtx-java

Color and movement
- offline test: gimbal rotate in preload sequence and saved video
- add laser power switch in GUI
- 微弱信号识别及过滤干扰目标: detect moving region
- send poweroff command to motor after closing
- add force exit function, such as reboot?
