MCPU suggestion

[jgauthier]

Hello,

I'm looking for an MCPU that can interface with a camera, and wireless. My objective is to grab the video data and send it over the wifi signal. One wifi device I am looking at is the 88W8801 which can be connected using a couple high speed interfaces (USB, SPI). Anyone have experience with an MCPU that can offer a recommendation?

Have you seen the ESP32CAM? Inexpensive, with camera, WiFi, easy to program

I haven't seen that one. Thanks for the recommendation. I am going to order a couple and see if they can pump 720p at 30FPS, which is my target resolution and frame rate.

720 p: yes

resolution	framesize
10	UXGA(1600×1200)
9	SXGA(1280×1024)
8	XGA(1024×768)
7	SVGA(800×600)
6	VGA(640×480)
5	CIF(400×296)
4	QVGA(320×240)
3	HQVGA(240×176)
0	QQVGA(160×120)
4	default

Table from here (German, sorry, but very informative). Here's another page in English, also very good.

30 fps: might be possible, see here. Will depend on resolution and quality. My own experiments resulted in more like 5 - 10 fps But I had only tinkered with the camera and by no means done any optimization. Also used max frame size, not 720p.

I saw that same thread. I am going to give it a try. It was cheap enough. If that doesn't work I may try an STM32H7 series. I have a nucleo that I can try. They are quick little things, but not sure if they are good enough for this.
