Before accessing these registers, write register 07 to 0xFE.

@xiaoxun 奇怪，我这边没问题啊。 你试试opencv这个 6.6.5.2： http://wiki.veye.cc/index.php/Mv_series_camera_appnotes_4_rpi/zh#.E4.BD.BF.E7.94.A8opencv.E9.A2.84.E8.A7.88GREY.E6.A0.BC.E5.BC.8F.E5.9B.BE.E5.83.8F

@hchorsi I'm sorry, due to the limitation of the ISP solution, this camera does not support ROI function for arbitrary sizes.

@milank OK. You are welcome.

@wangdada 这个时钟是mipi信号的一部分，并不是需要你的主板提供给camera的。

@ff1211 默认是打开AE AG的，这个现象是增益调节的太高了。你可以根据实际应用场景改为 纯手动模式，手动曝光手动增益，把增益配置的小一些，或者干脆配置为0. 还需要保持自动模式，则把最大增益调小。

@simonpi 不明白你的意思，wiki上都有啊~

@ff1211 不客气

@desperex The linux of this board is open source. firefly has contact information on the wiki page, and you can get a download link to the material after you purchase it and consult it.

@veye_xumm Thanks

@nimadibaj 0x3b This camera has isp module, so you can't control the sensor directly. please refer to the following code. http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_i2c/ https://github.com/veyeimaging/raspberrypi/blob/master/i2c_cmd/bin/veye_mipi_i2c.sh

@veye_xumm Hello, Thanks for the reply. We will check with a different FFC cable and give you updates.

@ff1211 said in MV-MIPI-SC130M在树莓派4上最大帧率只有22: enable_i2c_vc 不好意思忘了上传这个文件，你从github再更新一下吧，已经传上去了。

@milank @milank said in VEYE -MIPI-IMX462 - how to configure manual shutter&gain: I assume FW cannot be upgraded by the user, right? yes

@milank I think it was RF interference on the FFC cable.

@veye_xumm Ok, thanks.

@nathan-sinclair said in using veye-mipi-327, unedited h264 video for display in html video element: Just a query about whether it's possible to be sending the h264 video from the mipi-327 camera unedited, so that it can be displayed in a video element on a web page. The way we are currently doing this, is using a library on the client side called jmuxer, which, through a websocket directly is able to display arducam cameras. Is there something similar with the mipi-327 camera as seen in libcamera-examples? Sorry, we now only have a similar demo available in legacy mode via gstreamer. http://wiki.veye.cc/index.php/VEYE-MIPI-290/327_for_Raspberry_Pi#veye_raspcam:_raspcam_alike_toolkits

@thn The possible reason is that there are other signals on the i2c bus, causing the camera to misjudge. Is there any other device mounted on your i2c bus?
