Connect another CMOS global shutter matrix to OpenMV H7

Postby kornull » Thu Mar 19, 2020 9:17 am

Dear engineers from Openmv.
My question is:
Is it possible to connect another CMOS global shutter matrix to Open MV cam H7 throught DCMI?
If I do I would need to make changes in software?
I consider: MT9M021, MT9M031 or OV7251
Thanks a lot 8-)

Yes it's possible, you can design your own sensor module based on ours. The hardware and software are opensource you can find them on github.

Thank you iabdalkader for ur answer,

I have two additional questions:

1. What is a meaning of pins: RSVD1...RSVD5 - for what is each of them responsible for? (base.sh from: open MV Cam H7 Base Schematic)

2. I don't know if ur confirmation is also related to "If I do I would need to make changes in software?". I mean if I design my own sensor module based on yours "Global Shutter Camera Module" it will be necessary to make changes in yours software on github? its really important to me because im not so good in programming in C.

Thank You.

1. reserved pins.
2. yes, you need to write drivers for the new sensor.

RSVD1...RSVD5 are for future MIPI cameras.

Thanks guys,

I'v got next question:

Which files are responsible for camera driver (from github -> OpenMV) I want to check how many changes I'll have to make to use another matrix.

Thanks a lot.
