Cheap WiFi Webcam: ESP32 + OV2640 camera
-
@bearer said in Cheap WiFi Webcam: ESP32 + OV2640 camera:
does esp32 + enc26j80 (from memory) fit the bill? or even esp with SLIP ?
Looks like I need to write Ethernet library myself (modify existing one). They use "SPI" object and that's not available on esp32-cam, those pins are attached to the camera module. There should be HSPI available but for that I need to do a lot of search/replace + some initialization to use HSPI port on the esp .. we'll see .. should be simple but..

hmm, bummer, only tried it with the esp8266 eons ago.
i think i've seen some nutjob implement ethernet with just a line driver and some magnetics

@bearer interesting project but dunno if any of my switches support 10baseT and since this is for 8266 again need to rewrite it to fit esp32 .. I'll see how quickly I can fork the Ethernet library to make it use that HSPI that is supposedly available on esp32-cam (actually, first I'll just see if I can output anything on esp32-can via that hspi before I start editing that library).. we'll see .. W5500 is el cheapo, could be a good fit here.. and having both wifi and eth in a camera with sd card could be useful, even without sdcard..
I was hoping I will be able to find an open source camera out there for 20$ or under but

I'd thunk it'd work with any 10/100/1000 switch, I'd be surprised if people are makings switches that can only do 100/1000.
Anyways ,yeah, I was a little lolwhat? when i saw that video the first time, gotta love clever people with too much time on their hands :')

@bearer 10b2 is completely different framing, the protocol is totally different from 100b2 and 1000b2. I know my small switches don't do 10b2 (learned that the hard way, had to find some old hub with 100b2 uplink channel to connect some old silicon graphics and sun machines some time ago), dunno about my big managed switches if they do .. anyhow not making that, I don't think it's worth it... will see if I can get this esp32-cam to work somehow with w5500 and if not moving away from that... still have not tried that hacked firmware for the itead camera, found some additional data on that might be useful we'll see, or I'll brick one (thats why I purchased 2

ha, after a lot of search and replace...

yeah, it works. ESP32-CAM + W5500 streaming jpegs
