Usb To Serial Connection Camera Option

With the option to use the EZB in serial to USB you lose the option for the camera since the connections use the camera port. Is it possible to add another EZB like the IO Tiny to connect the camera too, then hard wire both EZBs together? I can't use Wi-Fi on either EZB.

There is a very specific reason I want to use the EZB camera and not a usb webcam, but i still need the EZB wired to the computer.

Edit: Please visit post #37 for the update on the usb/serial cable I used, new wiring diagram and notes

I will re edit all the correct wiring and repost so anyone else who wants to convert their ez camera to USB will have a correct wiring diagram if they use the PL2023.

Nice - glad it's working. I bet it works real fast and responsive too! The camera connected directly to the PC would be amazing fast

Here is the wiring diagram when using the PL2303 to convert the ez camera to a usb camera. The PL2303 has baud rates up to 12mbps, so it supports 3,333,333 baud for the ez camera. It’s $10 and works great!

Please not DO NOT cross the TX and the RX, the wiring diagram from China is incorrect. Please connect TX to TX and RX to RX.

Do not use the 5 volts from the cable but rather connect 3.3v and ground from the EZB using the regulated 3.3v on the Analog ports. also connect a ground from the EZB to RTC.

Hey guys I’m adding the camera to Alena. When connected to ARC and activated on the com port, I keep getting glitches in the image about every 30 to 40 secs. ( see below) Any idea what could be causing? I checked wiring and swapped out cameras and exhibits same behavior.

Either the rts and CTs are not connected correctly or the data wires are noisy

Ok I didn’t connect at all because of the quote from #24. Maybe I misunderstood.

You don't need cts or rts actually. I realized there's enough buffer on the pc

Maybe not enough buffer after all?!?

Oh right! Yes that’s right. I forgot, you don’t need CTs rts. The buffer is huge. Really huge.

So I’m guessing it’s noise on the signal line
