USB Connection To EZB V4

OK guys I have another question for everyone can you use the UART on the EZB V4 to connect to a USB rather than the camera port?

I want to hardwire my EZB's to my onboard PC but I also want to use my ez-robot camera with one of my EZB V4.

Yep, remember when we built the neopixel blaster @DJ? There was nothing we could do with the EZ-B to get the timing that fast. An Arduino (or equivalent) controller was needed to produce the signals for the WS2812B LEDs. I believe Dave Cochrane built a skill that incorporates an Arduino and Neopixels.

Well it looks like I will have to purchase an Arduino uno to deal with this.  And yes I found the skill for it thank you guys.  This project just keeps getting more and more complex and costly.  I guess that is expected.

Hello @smiller29, well I ran into a speed bump. The PL2303 uart-ttl adapter I ordered was the HX 'A' version (PL2303HXA) which as it turns out didn't get driver support in Windows 10. I had no idea that some chip versions didn't get driver support for Windows 8 and 10 (I guess some of the chip versions are legacy products) It seems like they come out with a new chip version almost every year!xD Here's the chip version Windows 10 support list:

Now I have to order another one. Learn from my mistakes I guessxD

I ordered two PL-2303HX that is said to work with Windows 10 32/64 bit so I hope it works.  I hope your test works.  I ordered a USB Camera but I am not sure it will fit in the chest where I want it like the EZ-Camera will.

Hey @smiller29 I received my PL2303TA USB-TTL adapter today and I've done a bit of testing with it. It connected to my laptop as soon as it was plugged in and appeared as a COM port. Using the serial terminal (PC) in ARC I was able to verify that it was communicating with local echo and that it could communicate at 3.3Mbaud. It is rated to go up to 6Mbaud max. Unfortunately, I can't seem to get images to come through with the camera yet but I'll press on tomorrow.

Local echo doesn’t use the adapter. Local echo means just display the characters you typed

to test a true echo, you’d need to connect rx and tx together in the uart
