Author Topic: How to switch IRCUT on hi3516?  (Read 3194 times)

I have a Hi3516 module with IMX122 sensor. I have serial and telnet access to the board, and have been happily coding my own web server for the camera. No trouble there. I can capture video, save it, stream it etc...

Where I'm stuck is I need to be able to read the ADC for the day/night sensor, and also set the IR CUT output to switch the IR filter.

How do I do this? Can I do it from the command line? Otherwise, what API do I call in the sdk?
This is my lowpower.sh file...(if that helps)

Hi,

I have obtained the source code for addressing and writing the GPIO which flips the IR/CUT, and tested that it works.

Thanks

So how to switch the IR then? I have a camera based on hi3518 with the same script bundled in the firmware, however I'm still unable to figure out how to enable the IR leds from the shell.
