@alex_ai First, let me explain the gain configuration logic for the GX-MIPI-IMX662. The IMX662 features 30dB of Analog Gain and supports High Conversion Gain (HCG). The HCG function acts as an amplification during the sensor's analog signal readout, equivalent to 15.3dB.
Therefore, when we configure the "Again" parameter, the actual range is [0, 45.3dB]. This means you can set the Analog Gain up to 45dB without enabling Digital Gain (Dgain).
Currently, our firmware integrates HCG into the "Again" setting, which may have caused some confusion during your testing.
As for the feature to read sensor registers, I have added it to the development roadmap. It will be provided later via a firmware update package.

@xu 识别到产品型号了，正常。

@veye_xumm Thanks!

@lkarthus said in IMX307如何调试图像参数？IMX307和IMX335如何同时使用？:

@seka OK~

@veye_xumm 是的 非阻塞缓存后写图，已经解决了。抓拍的图像基本模拟一次就有一张抓拍，因为闪一次时间是1ms 所以只抓到一张也是合理的。

@dan_lionking
You are welcome.

@veye_xumm 重新插拔了下线，目前已经能正常读到，看来应该是线没有接好

@lin 相机触发模式出图和流模式出图，对你的程序接收图像而言，没有区别啊！

@robot ok

@fire Yes, raspivid and raspistill works too on Ubuntu.

@npcdna
这个问题提出已经很久了，一直没有更新状态。 我会将状态标记为解决，如果需要，可以再次跟帖，或者直接打开问题。

@chjchoi I think this place means that the 954 chip is not detected properly on the i2c.

@veye_xumm 感谢

@vladimi-zheng 没有关系。

@veye_xumm

That's right. It worked with the lens. Thank you very much for your technical support.

@veye_xumm
好的好的，感谢您的建议

@watchever
Sorry, this can not be modified. IMX307 is slightly worse than 327 low illumination, but the actual difference is not very large.

@robot
有一种可能，你的i2c和mipi是错配的。

@jetsonnano
What a bummer, they should have open the code.
We have customers who use avermedia and avermedia helped with the driver porting work. They probably do it for volume customers only!

If you have the ability, you can try to decompile avermedia's dtb file, get the dts and then modify it into our module. But it will be more troublesome.
