@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.

@newleaf BTW, the I2C features are nice and work quite well. Was able to port the code over to Go. 🙂

@cheesefish 好的，不客气。

@lin 参考一下part7.3

@lukapercic The number of pins and the spacing of the connectors are different, so I believe they cannot be directly connected together.

Just wanted to provide a followup on this. Reached out to Seeed and they said they would order a camera and investigate further.

I also had some success on the Nano by reducing the cable length between the Nano and the camera (using a CSI-HDMI adapter from Arducam). Worked sometimes on first boot. Then stopped.

Regardless, we are nearing a deadline and decided to switch to the Xavier for a prototype. The Nano has been challenging due to reduced support from NVIDIA.

I believe you are right about device tree. Something different from first boot compared to reboot. Even with the longer cable, it was 100% consistent with this strange behavior.

@veye_xumm ok thank you. We'll try generating an external trigger and seeing how things sync up. We will follow up with more questions if we have any.

@veye_xumm 感谢感谢

@veye_xumm 楼主，我用的这个微雪的树莓派CM4扩展板，

能麻烦帮我看看么？

@hchorsi said in IMX335 trigger synchronization:

Can the IMX335 sensor be synchronized with an illumination source such as projector using trigger pins? What are the requirements for the trigger signal in terms of the frequency, amplitude, duty cycle,...?

Sorry, the VEYE-MIPI-IMX335 has an ISP module and does not support external synchronization and trigger signals.

@veye_xumm Thanks, this should be enough I think

针对RTSP这个，一般只需要一个rtspd服务器就行，可以移植live555，或者直接用gstreamer的rtsp服务器插件，甚至可以直接用ffmpeg进行rtsp推流，接收的时候，用vlc即可。

@liubo1999

读取0x0424寄存器地址的数据全是0x00,请问是不是我设置的报文发送的不正确？举个例子，数据类型是bool的数据，我可以发一个字节作为设置值吗？还是说必须一次设置4个字节？

所有数据类型，都是必须使用4个字节的。

还有一个问题，就是说，如果成功设置成为“MCU bypass mode”模式后，是不是仍然在当前的I2C总线上与传感器通讯？MCU只是作为透传功能是吗？

设置之后，电路上外部与sensor的i2c通信不经过mcu，是直接联系的。i2c地址也是各自sensor的地址了。

@veye_xumm 好的 感谢
