You are obviously knowledgeable, Graham, so we'll pose these questions to
you then.

We all know what SPI is.

I'm of the opinion that a lot of the terminology being used is being mixed,
slurred, shifted in such a way to make basic concepts difficult to
understand. I thought I would just talk about it.
What is SPI? You can use the terms UART and SPI interchangably. Bear with
me on this...my point is cul
This idea might not make too much sense at first...
Get a NEO6M GPS module connected to a UART on the BBB. Write a
quick-and-dirty 2D pythagorean NEMA-compliant routine that determines the
distance to each hotspot and then connect to the one that makes the most
sense (since radio frequency fiel
Interesting problem. I agree with the clock idea.
How I would do it is by looking holistically at the overall situation and
getting a timer interrupt function to periodically look at the cycle
counter and see if its over like , and if it is call the code that
recalibrates it before it m
OK, the civilized way to do this stuff. It's called 0.1" header, ok? You do
the traces on single-sided presensitized DIY PCB board and you solder the
header on the down side. Then you have all your p8 and p9 signals broken
out. Then the whole issue about where do I put all this stuff goes
away.
Best and fastest? Yes, yes.
Use C, namely GCC. We are men here.
OK, what you do is do it in hardware. Select a nice set of glue translating
your TTL to 3.3v which the BBB uses. Use SSR chips or just plain logic
chips to do this.
Next you'll be implementing quite a bit of hardware so get some
Mylar.

That is nice. Serious, serious. I likey. And the price is right.

I agree with my fellow posters that using an optoisolator here is not the
solution.
The solution is to use an isolated (preferably optoisolated) logic gate. In
this case an OR gate. The critical thing to mention here is that the BBB
uses 3.3V stuff which isn't TTL (which is 5V+ for on and 0V fo

For more options,
Ok, but seriously, these are great questions.
Standard for this kind of stuff is python (apparently). But I think C.
No such thing as a wireless UART in that a UART stands for "Universal
Asychronous Receiver/Transmitter" and its a chip that outputs a TTL signal
that requires wires to transmit t

This DOESN'T WORK but as far as I got.
I thought I would super-duper UART-ize my board. Still waiting for somebody
to tell me "how it is done" kinda thing.

Break out your PWM on to a PIC16Fx (using it crystal-controlled with
software-based PWM by counting the clock cycles per instruction) and then
use UART to control it.
An alternative fix, but it does give you nice isolation in the process.
Depending on how powerful your servos are, you might hav
I'd break it out on a PIC16F so I got isolation from the BBB itself using
their ADC's. Just read it in via UART. Then use the BBB to crunch the data,

OK, best way (and this really is an IoT question if you look at it) is to
look at the most efficient (ie. fastest, least labor intensive) way of
doing it. BBB's are small, so please don't try to install an SMTP server
and stuff on it when you can do this.

OK, I just got my BBB so I gotta talk a bit out of my butt (having not done
this yet myself).
What you need to do is get it "interrupt driven". However you do it.
