sc031gs: frame size err

[huangdiajd]

Using the SC031GS camera, the frame_size was found to be wrong. How large frame_size should be set for SC031GS. I see that the error message should be set to 200200, but I set 174144, which is not working. Of course, I also tried to change 174144 to 200200, but the same error will appear. How should I change the appropriate frame_size

After changing it to 200*200, I connected to the WiFi, but I could not connect to the website 192.168.4.1, which would cause an error

Please use the new branch for testing.

I changed it to VGA, and then it gave an error when connecting to the web page. Can you help me see what is the reason app task running... app task running... app task running...

The current xclk can be used is 10M.

The current xclk can be used is 10M. I have changed xclk from 16M to 10M, but it will show the following message

Please take a schematic diagram of the connection between the development board and the sensor you are using. I suspect this may be a hardware issue, as there were no issues with my testing here.

/ 我最后只能将xclk改到6M，但是这个帧率只有5fps了。然后xclk怎么才能提升或者说031gs这个帧率如何提升.

[WangYuxin-esp]

May I ask what frame rate do you expect to achieve at VGA resolution? I think this high-speed sensor signal line needs to be made very well. The current situation is likely a hardware issue.

[WangYuxin-esp]

20fps 可以的。目前应该已经有 20fps 了。只是你的 XCLK 低导致帧率未及预期。 输出的应是灰度图。不是 XCLK 的原因，是镜头、sensor 打样的问题。这个 sensor 完美的工作需要自己调试自动曝光、增益参数。 你可以通过 sensor_t *s = esp_camera_sensor_get(); s->set_reg(0x0211, 0x0b); 来控制 sensor 的寄存器。

这是 我的031手册，我应该看哪些寄存器部分，然后修改。

[WangYuxin-esp]

If the data is already available, even if it is bad, then ESP32 has completed its mission. You can communicate with the technical personnel of the original sensor factory regarding the subsequent image tuning work.

SC031GS可以直接接上ESP32-S3-EYE调试吗？ @WangYuxin-esp

[WangYuxin-esp]

This is not easy, because this high-speed sensor SC031GS requires a very short FPC. I have integrated SC031GS on my development board.

SC031GS可以直接接上ESP32-S3-EYE调试吗？ @WangYuxin-esp

Very cool work from WangYuxin-esp!, it really enables 640x480 resolution on SC031GS. But I´ve got distorced images at 640x480 resolution. Can it be because of the high PCLK(Pixel Clock) of 25MHz? Any suggestion?

See some results I´ve gotten (Pictures from my oscilloscope): pic1: pic2: pic3:

With lower resolutions, the results are better:

If the situation is the same with lowering the xclk, it may be a power issue.

[Eduardo-Brandt]

I have discovered that the problem was because of the BUS cable lenght. Mainly because of the PCLK (Pixel Clock) pin, that carries about 25MHz clock. I got very better results when I shortened the cables from 10cm to about 15mm of lenght. The 3.3V to 1.8V converters may worsen the problem also.
