## Notes on using gk7205v300 camera with imx335 sensor
|
|
|
|
In the main, working with the camera is no different from other gk cameras. Lite or fpv is flashed in the same way, or lite is updated to fpv.
|
|
The presence and location of pins for USB and UART should be viewed on the seller's page. For example, the camera purchased at [link](https://aliexpress.ru/item/1005005492432144.html) has USB
|
|
on the connector for the FPC cable and are named in the description WIFI_DP and WIFI_DN (USB DP/DN).
|
|
|
|
The nuances concern the resolution settings. The 1080p mode (setting size: 1920x1080 in majestic.yaml) produces 15 frames / second, which is of course unacceptable. It is necessary in the file `/etc/sensors/imx335_i2c_4M.ini`
|
|
comment out (via `;`) the line `clock=27MHz` and set `Isp_FrameRate=30`, then reboot the camera. The corrected files are in the [imx335_gk7205v300](/imx335_gk7205v300) directory.
|
|
The `size: 2592x1520` mode also works and produces 20 fps, but the viewing angle of the picture does not change, which suggests interpolation. But it is not known from what resolution - to what. In fact, the delay in 1520p@20 is lower and is about 165 ms, in 1080p@30 - 185 ms.

Also needed is [gkrcparams](gkrcparams.md) for smoother picture. |
