Multi Camera V2 Demos Don't Use Camera B #29

Closed HCastano closed 4 years ago

HCastano commented 4 years ago

Hi, I have the "Arducam Multi Camera Adapter Doubleplexer Stereo Module V2" connected to a Raspberry Pi Zero W and have been trying to get the shell samples to work. Unfortunately, they only seem to take photos from one camera (Camera A). The Stereo Module has UC444 Rev-C on the PCB.

I've tried the scripts in both RaspberryPi/.../Multi_Adapter_Board_2Channel and RaspberryPi/.../Multi_Adapter_Board_2Channel_uc444 and haven't been able to get images from both cameras on either.

The script in RaspberryPi/.../Multi_Adapter_Board_2Channel has no errors/warnings. When I run it I see the camera LEDs toggling on when it takes a photo with Camera A, and turning off when Camera B is supposed to take a photo (Camera A just ends up taking another photo).

For the one in RaspberryPi/.../Multi_Adapter_Board_2Channel_uc444 I get an error when trying to use i2cset, but I believe that's the same as #1 (just noting it down in case I'm mistaken).

I've tried flipping the cameras (e.g moving Camera A to the Camera B slot) and running the scripts again, and Camera A is still the only one that ends up taking a photo.

Let me know if you need more info.

Don‘t worry and I will try my best to help you. Please attach me your hardware connection and I will help you check it in detail. It seems the GPIO4 does not be driven normally.

Here is the hardware setup @UCTRONICS.

In case it matters, I'm using the following cameras.

Same issue but I am using Raspberry Pi 3B+. I urgently need a solution for this because we purchased one 4 channel and 2 channel adapters, and both are not working properly @UCTRONICS

After re-soldering the header onto the Raspberry Pi both cameras are taking photos using the pi_cam_uc444 shell script.

Immediately after re-soldering I wasn't able to get i2c-tools to work because of permission issues - they require sudo to use out of the box. Without the i2cset command running the cameras won't switch, so that's kind of an important detail. The error message I got in the case was:

Camera control callback cmd=0x4f525245mmal: No data received from sensor. Check all connections, including the Sunny one on the camera board

Hope that helps others.

Any update? I'm currently in the same issue. Trying to get it work on my Rasberry Pi 3B
