Hi, Is there a way to record an analog value ( kind of like the graph built in trend viewer ) and play the analog back to an output on command.
Thanks
-
Depending on the required sample rate, it would be pretty easy to do that on a BRX with analog.
-
Would it be possible to sample at 120hz?
What are the instructions/ steps to do this ?
I am trying to do a similar to this device

Thank you

The speed is fine.
How many channels do you need?
-
Ideally 4 but at least 3
Thanks

BRX can easily do it, but it will be June/July before the analog output modules are out. For now, the BX-DM1E-36 has the most onboard analog, but there are only 2 onboard outputs channels.
We may also end up adding DMX512 as a protocol option between now and then. You didn't mention it, but it is something we have done in testing, and I would like to add both master and slave versions, and possibly even ArtNet.

I would like to revisit this post now that tha analog cards have been released. What is the method to record and playback analog ? Also was dmx512 implemented?
Thanks

I'm pretty sure the FACTS analog modules are not fast enough to meet your requirement. The built-in channels are capable of nearly 1Khz, and I was of the understanding that they were targeting similar specs for the modules. Apparently not.
As for DMX, the current plan is to implement it in the BX-SERIO module. I have a software implementation for the internal port, but it takes some liberties that I would rather not put into product. By adding it to the BX-SERIO, we can implement it in hardware with no compromises.

So if I'm looking at the specs right, the Analog Input Expansion card has an update rate of 22.2Hz?
-
Yeah, that sounds correct.

Facts built the BRX analog modules not Host?

Correct. If there is enough interest in an analog module based on the built-in channel design (high-speed, universal voltage/current), we might look at Host doing a -3 expansion. We'll let the market drive that though.

Haven't got the Christmas lights taken down yet, eh? ;D

That would imply I got them up to start with. ;)
But in case my subtle suggestion wasn't obvious enough, those flashing lights might be controlled by a BRX CPU via DMX512. ;D

I was kinda getting a hint at that :)
