Nov 02 02:18:36 <set_> I can feel. I am getting closer. ServoCape!
Nov 02 02:19:23 <set_> Now, even though the bot so far cannot handle 1 and 2 simultaneously, a pause of 0.18 seconds works. I know...
Nov 02 02:19:36 <set_> You have already heard me say that before this time.
Nov 02 02:19:49 <set_> But! I am still trying.
Nov 02 02:20:30 <set_> There is a trick to it in my function that I have not unearthed yet.
Nov 02 02:20:40 <set_> Back to the books!
Nov 02 02:22:37 <set_> I did find this idea: https://docs.beagleboard.org/latest/books/beaglebone-cookbook/04motors/motors.html .
Nov 02 02:22:54 <set_> There is a listing of a servo motor .py file in it.
Nov 02 02:23:10 <set_> This gets me closer to understanding the servoCape.
Nov 02 02:23:19 <set_> Sort of...
Nov 02 02:37:30 <zmatt> set_: that stuff isn't really applicable to the servocape
Nov 02 02:37:43 <set_> I understand now. Okay.
Nov 02 02:37:53 <set_> No issue...
Nov 02 02:38:21 <set_> I still like how it describes how to initialize a servo on the BBB in question w/ Python3.
Nov 02 02:38:41 <zmatt> and why the 0.18s delays?  what happens without them?  also, what library was that that you were using, it was clearly a different one than mine which you were previously using
Nov 02 02:39:27 <set_> The delays seem to allow for the servos from the PCA9685 to not kill/shutdown the BBB prematurely.
Nov 02 02:39:37 <set_> I have not figured it out yet.
Nov 02 02:40:04 <set_> I am using a lib. from a fellow on the forums.
Nov 02 02:40:05 <zmatt> oh you mean you're just overloading your power supply? lol
Nov 02 02:40:12 <set_> I asked him...
Nov 02 02:40:14 <set_> Right.
Nov 02 02:40:18 <set_> Somehow.
Nov 02 02:40:56 <set_> I asked him about managing more than a servo at a time. He wants me to figure it out. So, here I am trying.
Nov 02 02:42:09 <zmatt> "to not kill/shutdown the BBB prematurely" .. am I understanding correctly that you're seeing the BBB power off or reboot if you omit the delays?
Nov 02 02:42:31 <set_> yes. the BBB powers off when I run the source w/out the delays.
Nov 02 02:43:28 <set_> I posted a video the other day. It is the running of eight servos but w/ delays.
Nov 02 02:43:43 <set_> It runs them fine but not at the same time for whatever reason.
Nov 02 02:44:27 <zmatt> how are the servos powered?
Nov 02 02:44:50 <set_> sys_5v and a barrel jack.
Nov 02 02:45:17 <set_> I tried vdd_5v for powering the ServoCape.
Nov 02 02:45:48 <set_> But...as I recall, the vdd_5v is for Cape power and not to power the servos from/to the connectors?
Nov 02 02:47:08 <zmatt> I mean, it doesn't really matter how you power the servos as long as it's the right voltage and can provide enough current... and it sounds like sys_5v can't provide enough current to drive multiple of the servos you're using at once
Nov 02 02:47:30 <set_> Right. But...on the Cape, it states 5v maximum.
Nov 02 02:47:44 <set_> Is that not odd?
Nov 02 02:49:12 <zmatt> is that connector X1 ?
Nov 02 02:49:19 <set_> Is that connector, the one on the ServoCape, for making another circuit?
Nov 02 02:49:32 <set_> it says 5v IN Max.
Nov 02 02:49:41 <set_> It is the only Blue connector on the ServoCape.
Nov 02 02:49:54 <set_> x1. yes.
Nov 02 02:50:58 <zmatt> based on the schematic it only appears to go to the servo output headers so I don't see any reason for it to really care about the voltage used
Nov 02 02:51:27 <set_> Okay.
Nov 02 02:51:32 <zmatt> it should simply be whatever the servos are expecting
Nov 02 02:51:37 <set_> I guess I can put more in it and test it.
Nov 02 02:51:38 <set_> Right.
Nov 02 02:51:49 <zmatt> but the main issue here is current capability, not voltage
Nov 02 02:51:53 <set_> i can put 5v w/ a greater A.
Nov 02 02:51:59 <set_> Right.
Nov 02 02:52:46 <set_> The servos are listed at a particular 5v @ ______. Please hold. Let me get the info. of these servos.
Nov 02 02:54:47 <set_> It does not say...
Nov 02 02:54:55 <set_> Speed : 0.16 sec/60°(5V)
Nov 02 02:56:13 <set_> So, the barrel jack in its connector on the BBB, will not supply enough amperage or total current to handle all these motors.
Nov 02 02:56:28 <set_> Dang it.
Nov 02 02:56:41 <set_> That makes sense.
Nov 02 02:56:58 <set_> The idea I got was from a maestro controller...
Nov 02 02:57:31 <set_> But...it was supplied by a large battery for the quadruped.
Nov 02 02:58:10 <set_> I have another ServoCape on order. So, I will test this one w/ a higher amperage at 5v.
Nov 02 02:58:47 <set_> This is the first one I got a while back. So, it actually came w/out input headers. So, I can test it.
