Hello,

I am currently working on a project which will involve the use of a camera module to be interfaced with the MSP432 microcontroller. My only concern is which camera would be ideal to use with TI and not give me problems with SPI clocks. I am looking for something which could ideally work with the processor. Currently I have the OV2640 Arducam-M-2MP which I read works with an Arduino board and several other boards, which have the necessary CPU clock frequencies for the required task of capturing frames, not with real time video processing but I am guessing this is close to impossible as this requires such higher clocks. I also have the OpenMV M7 camera which has an integrated ARM processor although this would make the effort a much more difficult task and I see it unnecessary as I would have to involve UART communications which I need to reserve for other peripherals. Any suggestions would be greatly appretiated, I just need good guidance so I can stop shopping for the wrong components.

 

I don't think 48 mhz going to be fast enough video will be slow use a pi or something like it

I am strictly required to use the MSP432, I could alternatively do image capture which will continuously capture images every second or two so that way the clock frequency can be handled by the processor?

 

I been looking at this for about a month I want do the same thing.
There are cams that do uart and spi https://www.ebay.com/i/281639729684?chn=ps&dispItem=1

YEAH. that's exactly the one I own at the moment. I was thinking since in the specs the SPI speed is 8 MHz I think this would suffice with the microcontroller. I should look into the reference for the processor and get to it.

 

I am no expert on these sort of things and I don't know if this relates to a communication problem. Are you just shifting data from camera to memory.......or are you doing some kind of processing?

Doesn't that chip have a hardware multiplier? Have you worked with this chip before?

The data sheet(157 pages) and the MSP432 manual(802 pages) is on my reading list.

 

It's got all kinds of stuff I don't no how fast a 48 mhz chip can do video but it has 4 uart's so even a serial cam should be doable.

You can add wifi to it so with dma you not have a hard time sending video out don't think. But that's a lot fancier chip then the ti chips I've used.

It's going to involve real time processing either of video or image capturing. I am pretty sure that the video is kind of heavy loaded for the processor clock rate but I am pretty sure still images can be captured constantly and sent out to a phone app, which is the desired output: Processing the images every 1 or 2 seconds, having the processor process this data and send it out to said app. The processor does have a multiplier but I won't be able to use it with ISRs which I think are necessary for said application. I have worked with the MSP430 before, and now moving on to the 432 which shouldn't be hard to learn as it comes from the same family and concept.

Yeah. I was thinking of doing serial comms. as this makes the task much better at handling and processing. I don't think the chip does have the capability to handle real time video processing so I am guessing image capture every few seconds would be a much more feasible option.

 

It looks like it could forward the video using wifi have to read up on that.
