Hey DJ,

Not to detract from another great update, but what would the possibility be of having the AutoPosition panels allow you to use multiple EZ-B's by specifying which board and then digital pin on that board you are controlling? If you need a tester, I would be happy to do so:)


Unfortunately no - the delay between each EZ-B's wifi and communication will prevent an auto positioner from controlling more than one EZ-B at a time. There will need to be multiple Auto Positioners, each with their own EZ-B specified to achieve what you're asking. It's a limitation of timing for syncing over the network. The Auto Position uses high precision calculations based on the ez-b's communication speed to synchronize the servo positions.


cool, I will give it a try as soon as I have time to jump back into the project.


@DJ Would it be possible to use the serial connection to overcome issues with wireless? For example, could you connect 3 ezb ' s using the high speed serial connections as a way to sync multiple servos between controllers in one Auto Position control? It may still be too slow. I am just throwing out an idea. This would allow 3 ezb ' s to be attached to a master controller and might work.


Bandwidth of UART/Serial is too slow for the EZ-B. The EZ-B works at 10mbps and serial without proper rts/cts and short wires will have issues with anything over 1mbps

Also, the EZ-B doesn't accept commands over the UART - limited to the WiFi.

We have considered a USB version in the future - when we have more resources:)


Okay, I wasn't sure if the issue was latency or speed. Thanks for the answer. My mind will quit trying to figure out a way around it:)


If I think of something, i'll let you know:D


Great release. Thanks for returning the color in the UI.
