@lin 可能是内核版本不太一致吧。

RE: IMX-287M: How to synchronize video frame capture with an LED?
@etale_cohomology said in IMX-287M: How to synchronize video frame capture with an LED?:
./mv_mipi_i2c.sh -r -f trgexp_delay -b 6
./mv_mipi_i2c.sh -r -f trginterval -b 6In video streaming mode, these two parameters do not take effect. The camera will output the strobe control signal based on the actual exposure time, whether it is in manual exposure mode or automatic exposure mode.

RE: IMX462 and Jetson Nano problem
@joe The software part of the work seems fine. Next, we need to check if the hardware connections are correct, paying particular attention to the orientation of the FFC cable.

RE: 相机硬触发,采集图像
@lin 你现在用的这个板子,只引出来了2个2lane的mipi接口。无法完成接入两个4lane的相机的工作。你需要换个板子了。

@newleaf Hi, have you made any further progress on this issue?

RE: IMX-287M: How to synchronize video frame capture with an LED?
- If your IMX287 is running in stream mode, please use the upgrade package from the following link for the upgrade:
https://www.mediafire.com/file/d4yjibcjp1hw8z8/MV-MIPI-IMX287M_C1.37_L2.04_20240306_beta_upgrade.bin/file - The camera will generate its own strobe synchronization signal. I suggest using this signal to drive your LED instead of using the Raspberry Pi's IO. For more details on the principle, please refer to the following link:
https://wiki.veye.cc/index.php/Mv_mipi_camera_manual#Strobe - On the ADP-MV1 board, the J3-5 pin will output the strobe signal by default.

RE: RAW-MIPI-SC132M硬触发导致图像采集丢失
@cheesefish
根据你的这个提示,应该是mipi信号质量太差了。
你可否拍一下整个系统的照片,再拍一下转接板的正反面照片我看看。
注意,排线长度不能太长;转接板上mipi信号要注意等长处理,阻抗匹配;应用环境的电磁干扰多不多? -
RE: 相机硬触发,采集图像
@lin 不好意思,昨天忘了说一个事情。改成4lane之后,用脚本paramsave保存一下参数。
然后,需要修改一下dts中的lane的定义——需要改为4lane才可以。
此外,需要使用新版本的ADP-MV2,这个板子增加了22pin的那个排线接口。你可以看一下跟你手上的ADP-MV2是不是一样。

RE: 相机硬触发,采集图像
@lin 这款相机在4lane模式下,才可以支持到120fps。 你需要配置一下lanenum,然后再配置fps。
此外,任何时候你都可以通过maxfps指令来读取当前支持的最大帧率。 -
RE: IMX462 15pin 1mm pitch to 18pin to 0.5mm pitch connection
@lukapercic The number of pins and the spacing of the connectors are different, so I believe they cannot be directly connected together.

RE: v4l2函数获取曝光值,为什么不行
@lin said in v4l2函数获取曝光值,为什么不行:
我换了0xC10就可以写了,请问一下,更改相机的帧率为什么media-ctl拓扑图中没变化,
分辨率和帧率你最好用media-ctl去改。嵌入式主板系统启动的时候会询问相机,后面只有media-ctl改动的时候才改驱动中的配置,并下发相机。
你用mv_mipi_i2c.sh直接改了相机寄存器,嵌入式主板中的驱动部分并不会获得通知。 -
RE: Do you have any plans to support color machine vision cameras?
@roman I'm sorry, we do not have that plan at the moment.

@fuhesong 我看您做的这个东东挺有意思的,你有自己的blog之类的吗?
