00:08 rue_house mm
00:08 rue_house we need someone working on a project
00:08 rue_house an interesting one
00:14 rue_house http://www.voip-info.org/wiki/view/VoipPack+VOG+4000+and+asterisk
00:14 rue_house I wonder if I can point two of them at each other
00:17 pigpenguin well the sopa protest has started
02:53 rue_bed its almost 1am, I'm gettin close ot giving up on sleep
03:15 elektrinis its 11 am
10:32 theBear what general topic ? crazy network admins
10:35 Steffanx uh?
11:29 KongfuPanda lol
11:29 KongfuPanda check this out: http://www.youtube.com/watch?feature=player_embedded&v=xrDOFbLw8pU
11:29 KongfuPanda anway, I'm off now
11:30 KongfuPanda cya :)
19:45 rue_house I think I'm gonna make an avr based chip programmer
19:45 rue_house for biod eeproms and 8051 chips
19:45 rue_house bios
19:45 rue_house this new keybaord sucks
19:49 Tom_itx what's your interest in 8051's lately?
19:50 rue_house the mecha needs controllers with a parallel bus
19:50 rue_house so I'm gearing up for that
19:50 Tom_itx they do?
19:50 rue_house the 8051 are made in some pretty good speeds
19:50 rue_house the io time on avrs would be too high
19:50 Tom_itx what was their main purpose in life?
19:50 Tom_itx kbd?
19:51 rue_house the 8051 can access more memory and io faster
19:51 rue_house 8051 are used all over the place
19:51 rue_house often in industrial stuff
19:52 rue_house I'm using avrs as slave adc's, cause their cheaper than real adc's
19:52 Tom_itx are they accurate enough?
19:52 rue_house 10 bit is fine
20:02 Tom_itx are they more controllers or processors?
20:04 rue_house they can be either, like the hc11
20:04 rue_house there is a pin to swith between port and bus mode
20:05 rue_house the one I'm playing with clocks up to 40Mhz
20:05 rue_house which is barely comperable mip wise to an avr, but gains from the access time on io
20:09 Tom_itx you have any boards for them?
20:12 rue_house sorry, being its copyright infringement day I was just gawking that the phone book has no copyright on it
20:13 rue_house no, no board for them
20:13 rue_house I have one breadboarded right now
20:13 rue_house but the mecha will have a whole pile of parallel io chips, so it'll be pretty specific
20:16 rue_house each of the (5?) 8051 will have about 37 solinoids and 112 adc channels to manage
20:16 rue_house about 10 axies per chip
20:17 rue_house I think a 40Mhz 8051 shouldn't have a problem staying on 10 pid loops
20:18 Tom_itx never messed with one
20:18 rue_house their not much different than the hc11
20:18 rue_house relativly primitive chip, wide support cause of its age
20:18 Tom_itx i figured as much
20:19 Tom_itx been copied quite a bit too haven't they?
20:20 rue_house the nxp version can be flashed over its serial port via a built in bootloader in an alternate memory page
20:20 rue_house you send it an ihex file
20:21 rue_house .. a bit slowly
20:21 rue_house it autobauds the port on startup
20:21 rue_house 400msec to send it U
20:28 Tom_itx hope you write tight code
20:29 rue_house thats just to catch the bootloadedr
20:30 rue_house if you stream U at it, you catch the bootloader on startup
20:30 Tom_itx oh
20:30 rue_house as soon as it catches, it echo's the characters back to you
20:30 rue_house for each ihex line you send, it replies with . for ok and X for problem
20:31 rue_house you can do chip erase and read memory
