Mar 19 03:11:25 <newblue> just tried some cable/power combinations with a powered usb hub
Mar 19 03:11:34 <newblue> at this point i can only conclude that it's a problem with the beaglebone blue
Mar 19 10:12:16 <madhu> Hi All
Mar 19 10:12:35 <madhu> does anybody knows how to enable uart2 in BBB
Mar 19 10:39:18 <madhu> Hi All
Mar 19 10:39:26 <madhu> does anybody knows how to enable uart2 in BBB
Mar 19 10:41:53 <Akex__> madhu https://billwaa.wordpress.com/2014/10/02/beaglebone-black-enable-on-board-serial-uart/
Mar 19 10:42:00 <Akex__> google is your friend
Mar 19 10:42:05 <Akex__> or not ...
Mar 19 10:43:47 <madhu> I did boss
Mar 19 10:43:54 <madhu> but no luck
Mar 19 10:44:03 <madhu> I tried those methods but no lucl
Mar 19 10:55:38 <tbr> you could explain your predicament in more detail
Mar 19 10:56:06 <tbr> e.g. which distribution and version thereof you run on the BBB
Mar 19 10:56:14 <tbr> also what exactly you've tried
Mar 19 10:56:22 <tbr> what you are attaching to UART2
Mar 19 10:56:23 <tbr> etc
Mar 19 11:01:57 <Palmnano> Hey there!
Mar 19 11:03:21 <Palmnano> I have a minor problem with my BBB. There's a i2c sensor that I (unfortunately) need to use, but its address is 0x78, which is reserved. Does anybody know how to address this sensor in C code?
Mar 19 11:38:40 <zmatt> EvilDragon: reserved?
Mar 19 11:38:41 <zmatt> eh
Mar 19 11:38:44 <zmatt> Palmnano: reserved?
Mar 19 11:38:47 <zmatt> in what sense>
Mar 19 11:39:55 * zmatt grabs The Spec
Mar 19 11:40:36 <zmatt> 0x78 is not its address
Mar 19 11:40:48 <zmatt> it's the start of a 10-bit address (encoded in two bytes)
Mar 19 11:41:20 <Palmnano> well, the bits 11110... indicate a 10 bit adressing. But my address is a 7 bit address starting with these bits
Mar 19 11:41:27 <Palmnano> thats the problem
Mar 19 11:42:00 <zmatt> well, step one is to yell at the manufacturer that they're idiots
Mar 19 11:42:20 <Palmnano> yupp...
Mar 19 11:42:30 <zmatt> it's not possible to interpret their overall protocol *as if* it's 10-bit addressing?
Mar 19 11:42:38 <zmatt> what sort of messages do they use?
Mar 19 11:43:17 <Palmnano> the second byte needs to be read unfortunately. so I cant just write another byte
Mar 19 11:43:39 <Palmnano> its a Honeywell  SSCSRNN1.6BA7A3
Mar 19 11:44:08 <Palmnano> my arduino can address this thing just fine
Mar 19 11:44:38 <zmatt> a read from 10-bit address 0x7800 actually looks like:   wr(slave=78,data=00), read(slave=78, ..)
Mar 19 11:44:59 <zmatt> i.e. exactly the same as the typical pattern for reading register
Mar 19 11:45:30 <zmatt> and yeah it seems likely the i2c controller has no problem with it
Mar 19 11:45:40 <zmatt> what error do you get exactly?
Mar 19 11:45:48 <Palmnano> its a pretty simple sensor, so it doesn't have registers.
Mar 19 11:46:57 <Palmnano> well, i don't receive anything from the sensor
Mar 19 11:47:39 <zmatt> that is technically not possible, either you got an error or you received data
Mar 19 11:48:43 <Palmnano> I'll look into it again
Mar 19 11:50:03 <zmatt> I don't get the impression it's being disallowed
Mar 19 11:52:41 <zmatt> ok i2cget does refuse it
Mar 19 11:52:45 <Palmnano> hm... okay great. My program crashes now. Maybe I should just try it with another beaglebone...
Mar 19 11:53:04 <zmatt> software bugs are rarely solved by swapping out hardware
Mar 19 11:53:53 <Palmnano> i'm currently using ioctl calls for everything
Mar 19 11:54:43 <zmatt> which is fine, though unnecessary if you really only need read transactions
Mar 19 11:55:40 <zmatt> ahhhh
Mar 19 11:55:54 <zmatt> they're using one-left-shifted addresses
Mar 19 11:56:08 <Palmnano> oh...
Mar 19 11:56:18 <zmatt> so it's 0x3c actually
Mar 19 11:56:27 <zmatt> annoying when people do that
Mar 19 11:57:06 <Palmnano> thank you very much!
Mar 19 11:57:10 <zmatt> they list as standard addresses (in hex) 28, 38, 48, 58, 68, 78, 88, and 98
Mar 19 11:57:16 <zmatt> those last two were the giveaway :)
Mar 19 11:57:47 <Palmnano> oh gosh, that is annoying
Mar 19 11:58:10 <Palmnano> its working! :D
Mar 19 11:58:17 <Palmnano> thanks a lot! :)
Mar 19 11:58:21 <zmatt> yay :)
Mar 19 15:27:02 <newblue> hi, so I have a new beaglebone blue, it doesn’t register with my MBP or linux laptops, when i plug in nothing comes up in dmesg or lsusb, i’ve tried with different cables, a powered usb hub, and an external 12v adapter. is there anything anyone else can think of to try and get this working?
Mar 19 20:41:40 <jamesaxl> i see that python lib does not work on kernel 4.
Mar 20 01:07:20 <Jase_> Can anyone help with BBB running this latest greatest release and Node-Red gpio not working?
Mar 20 01:08:10 <Jase_> I don't wanna deploy something with an older release unless I have to
Mar 20 01:13:31 <Jase_> :(
Mar 20 02:31:15 <ayjay_t> tbh i didn't really understand the question but i'm also not familiar with node-red gpio
Mar 20 02:41:47 <ver|laptop> http://nodered.org/docs/hardware/beagleboneblack - looks easy enough to me.
