issue getting jpeg format on iMXRT1160-EVK with OV5640 camera

Hi,

I have the iMXRT1160-EVK with OV5640 camera module and I need to operate it to output JPEG images. I don't run RTOS, but run in bare metal.

Since there are many registers on OV5640 and some do not have specific definition in Omnivision datasheet, I'm looking for an example code (C language) that configures the camera to get compressed images and output in JPEG format.

There is an example from NXP that outputs only raw data pictures and the compression to JPEG had to be processed on the NXP processor which took a lot of time (600ms) consuming battery energy.

Can anyone help with example code that outputs JPEG pictures?

Hi @ofirvn ,

No, we haven't OV5640 jpeg example. I searched on internet and found something for your customer to refer to.
