Nov 18 06:26:20 <Guest22> Hello,
Nov 18 06:26:21 <Guest22> does anybody know from where I can get BBAI with extended temperature ranges from -40C to 85C?
Nov 18 06:27:15 <Guest22> similar to the enhanced version of BBE offered by SanCloud?
Nov 18 10:14:42 <set_> I thought the ServoCape was faulty or it was my programming. Either way, it was not. The servos are faulty. Blah!
Nov 18 10:16:53 <set_> In the clear! speaking of the servoCape, is there going to be an updated versioning coming up?
Nov 18 10:48:16 <set_> Sorry. Incorrect am I here...again. The servos in question work. Time to try the connections on the servoCape and test my source some more. Aw! Too much, too much.
Nov 18 11:02:45 <set_> Okay. If...forget it.
Nov 18 11:02:49 <set_> Everything works.
Nov 18 11:47:41 <set_> Hello Again, if I run too many servos at once on the ServoCape, would some of them cease to work due to something?
Nov 18 11:48:39 <set_> For instance, "something" could be amperage or voltage or anything else that gets in the way at a particular time.
Nov 18 11:49:22 <set_> I have found that all the servos are working, i.e. eight of them. I have also found that running three at a time is fine.
Nov 18 11:50:07 <set_> Running eight of them at the same freq. and duty_cyle seem to not allow for all of them to move at once or at all, i.e. just some of them move.
Nov 18 11:51:42 <set_> I mean...what is a test method to find out when, time wise, things go "south"?
Nov 18 11:52:46 <set_> I only have two channels for testing. Would I test the /dev/i2c-2 device on the BBB for testing this idea?
Nov 18 12:09:29 <set_> I mean...do I need a real i2c/spi tester or is it possible to test w/ an oscilloscope?
Nov 18 12:31:27 <set_> Okay...I see why there is no cure. i2c is complicated and drawn out. I will keep on reading.
Nov 18 12:32:20 <set_> If the i2c buses on the am335x do not support fast mode, how is the ServoCape working w/ the PCA9685 or is allowing/denying fast mode on the PCA9685 an option?
Nov 18 12:38:27 <set_> I found a ti doc on i2c testing w/ an oscilloscope. Forget me...I will just keep reading. Forget all the items at hand from me. Sorry to ask so many questions.
Nov 19 00:56:46 <set_> You guys?
Nov 19 00:57:28 <set_> Fri. Funday?
Nov 19 00:58:08 <set_> It is only 7:00 at my place.
Nov 19 00:58:42 <set_> Three hours of total networking and fun in place!
Nov 19 00:59:04 <set_> Mingle much?
Nov 19 00:59:18 <set_> About the BBB and am335x of course!
Nov 19 01:00:13 <set_> So, a little birdie told me that even though the PCA9685 supports super fast data frequencies for i2c, it is the maximum and not a given.
Nov 19 01:01:26 <set_> This means that even since the am335x does not support that frequency of 4 or 5MHz for the i2c bus, the PCA9685 can still listen to the bus from the BBB since frequencies can be lower than the maximum freq.
Nov 19 01:02:24 <set_> I can see it work. So, that has to be true. Now, onto finer details!
Nov 19 01:02:54 <zmatt> set_: whatever your problem is, I can say with fair confidence it's not i2c-related
Nov 19 01:03:01 <set_> I know.
Nov 19 01:03:16 <set_> I am enjoying i2c since it works just fine.
Nov 19 01:03:47 <set_> I have brain issues. Nevertheless, the show must go on!
Nov 19 01:05:05 <set_> @zmatt: Thank you for at least letting me know something.
Nov 19 01:05:20 <set_> And yes, it is not i2c related.
Nov 19 01:05:28 <set_> i2c works!
Nov 19 01:05:56 <set_> My mechanical apptitude is blight, sparce, and refuted.
Nov 19 01:06:17 <set_> So, b/c of those three words, my i2c usage has suffered.
Nov 19 01:06:38 <set_> This has put a damper on my BBB related dealings.
Nov 19 01:06:48 <set_> But...learning slow over here!
Nov 19 01:08:07 <set_> That PCA9685 from NXP has a lengthy, not TRM lengthy, datasheet w/ tons of juicy info.
Nov 19 01:09:25 <set_> I almost figured out how to code something from the datasheet. It was like a blip of thought and then it was gone. I should have had pen and paper. Aw!
