Working with CSI
« on: February 17, 2022, 06:29:12 pm »
I'm working with an Allwinner A33, which is a 1.2Ghz quad core MPU. I want to connect this to two cameras, however, I have two problems.
  • There is only one CSI bus.
  • The CSI format is "CCIR601" which appears to be synonymous to: Rec. 601, BT. 601 and ITU.R
Here are some details pulled from the datasheet.

My question is a four-parter.
  • Is there a way to interface two camera into the same bus?
  • Is the defacto standard to find a sensor that has this output, or do some conversion? In hardware or otherwise.
  • Does anyone have some documents or resources for learning more about this? I'm not sure if it's obvious but I'm pretty new to working with cameras at the sensor level.
  • Is there a huge matrix of camera sensors anywhere?

You can use 2:1 multiplexer, I used this TS3DV642A0RUAR. You will only be able to get data of one camera at a time. I dont know your exact requirements and my reply is probably too late. Might be helpful to future someone.
