| 00:30.17 | RobotGuy | I just ordered more stuff from TI. :) |
| 01:23.13 | g1powermac_PB | hehe |
| 01:29.20 | g1powermac_PB | so what ya ordered? |
| 01:40.48 | RobotGuy | ZigBee stuff, USB stuff. |
| 01:40.57 | g1powermac_PB | cool |
| 01:41.15 | RobotGuy | I have a new opportunity to spread info about Hammer now. :) |
| 01:41.29 | g1powermac_PB | heh |
| 01:41.47 | g1powermac_PB | so did you get the cc2480? |
| 01:42.03 | RobotGuy | I ordered some of thise, and the cc2510 and the cc2431. |
| 01:42.17 | RobotGuy | s/thise/those |
| 01:42.26 | g1powermac_PB | nice |
| 01:42.53 | RobotGuy | I could see possibly using the cc2431 as a communications processor. |
| 01:43.13 | g1powermac_PB | yea |
| 01:43.31 | RobotGuy | You are getting me interested in the 805x processors now. |
| 01:43.39 | g1powermac_PB | looks around ti's site for more interesting chips, this could end badly ;-) |
| 01:44.03 | g1powermac_PB | woot, I got someone into 8051s :-) |
| 01:44.08 | RobotGuy | g1powermac_PB: Everytime I look at TI, Analog Devices, or Maxim, I end up with a parts order. |
| 01:44.24 | g1powermac_PB | don't forget freescale too :-) |
| 01:44.32 | RobotGuy | The real question is can the 805x be developed for under Linux? |
| 01:44.38 | g1powermac_PB | sure |
| 01:44.44 | *** join/#edev chouimat (n=dieu@r2351064.cidc.net) |
| 01:44.44 | g1powermac_PB | sdcc is the compiler |
| 01:45.06 | RobotGuy | Oh yeah, Freescale always makes me drool, and Luminary Micro also. Got to get an LM3S6965 eval board. |
| 01:45.10 | g1powermac_PB | not sure how well this particular chip is supported in sdcc though |
| 01:45.14 | RobotGuy | Ahh, OK |
| 01:45.27 | g1powermac_PB | ya might need to write a header file for it |
| 01:45.31 | g1powermac_PB | but that isn't too hard |
| 01:45.40 | RobotGuy | I can write header files/ :) |
| 01:46.33 | RobotGuy | I've been seriously thinking saving so I can get a New Micros Servo Pod. |
| 01:46.35 | g1powermac_PB | hmmmm, ti has dsps. . . |
| 01:46.46 | RobotGuy | I have some of their DSP chips. ") |
| 01:47.15 | g1powermac_PB | a dsp chip would be quite interesting to use in my biosensors I'm going to build |
| 01:47.24 | RobotGuy | Most definitely! |
| 01:48.02 | RobotGuy | I think I am definitely going to get an NGW100 network gateway kit also. |
| 01:48.23 | RobotGuy | One of these days when I have money. |
| 01:49.32 | RobotGuy | The New Micros boards use a lot of Freescale DSPs |
| 01:49.46 | g1powermac_PB | yea, I looked at freescales too |
| 01:50.57 | RobotGuy | Look at http://www.newmicros.com/cgi-bin/store/order.cgi?form=prod_detail&part=ServoPod&id=yhjOn5innV1mwHErUa3BQ3Thx4sRJSIn |
| 01:53.50 | *** join/#edev Appleman1234 (n=Appleman@CPE-121-222-170-32.qld.bigpond.net.au) |
| 02:11.12 | g1powermac_PB | hmm, interesting |
| 02:23.39 | RobotGuy | Neat board, yes? |
| 02:23.50 | g1powermac_PB | ya |
| 02:24.27 | RobotGuy | A little more expensive than I would like, but it really has ALL the control features I would want for W.A.L.T.E.R. |
| 02:25.17 | RobotGuy | I believe I can do all of that with the Luminary Micro LM3S6965 too though, and for just $69.00 |
| 02:25.37 | RobotGuy | Well, maybe not ALL of that, but as much as I need it to do. |
| 02:31.02 | RobotGuy | I'm intrigued by the IsoMax language and have been looking at it a bit. |
| 02:31.22 | RobotGuy | (for the servo pod) |
| 02:32.42 | RobotGuy | I would like to build one robot around the ServoPod or perhaps IsoPodX |
| 02:42.23 | g1powermac_PB | hmm, interesting chip: http://www.ramtron.com/products/microcontrollers/8051-mcus-product.aspx?id=28 |
| 02:43.22 | g1powermac_PB | no adc though |
| 02:53.58 | RobotGuy | g1powermac_PB: No ADC means no use for robots. |
| 02:54.19 | g1powermac_PB | yea, not much use for me either |
| 02:54.36 | g1powermac_PB | however it has interesting math stuff to do dsp stuff |
| 02:54.57 | RobotGuy | That is true. I think I would use a PlugPodS for DSP and such. |
| 02:55.13 | g1powermac_PB | yea |
| 02:55.35 | RobotGuy | 12 bit ADCs on it. |
| 02:55.49 | RobotGuy | Some of the TI DSPs have 16 ch 12 bit ADC. |
| 02:56.00 | g1powermac_PB | mmm |
| 02:56.33 | RobotGuy | I have some of those DSP chips. :) |
| 02:56.51 | g1powermac_PB | whats the number? |
| 03:01.15 | g1powermac_PB | hmm, time for bed |

| 20:30.09 | g1powermac_PB | any experienced zigbee people here? |
| 20:30.40 | g1powermac_PB | is pondering how hard it would be to use the raw hardware just to make a simple star network |
| 20:39.08 | MonMotha | depends on the radio |
| 20:39.23 | MonMotha | the radio we've used is REALLY simple to talk to if you just want to chuck bits out on the air |
| 20:39.36 | g1powermac_PB | hmm |
| 20:39.49 | g1powermac_PB | well, I'm looking at the one inside the cc2481 SoC |
| 20:39.56 | MonMotha | I have no clue how the TI ones work |
| 20:40.12 | MonMotha | the Atmel one is a state machine with a SPI interface |
| 20:40.36 | MonMotha | I managed to hack a Linux driver together for it in about 2.5 days, most of that being linux related stuff, not chip related |
| 20:41.01 | g1powermac_PB | well, this sucker gives total access to the hardware stuff it seems |
| 20:42.26 | MonMotha | the Atmel one does, too |
| 20:42.32 | MonMotha | but use what you want obviously |
| 20:42.37 | MonMotha | I can only speak for what I've used, though |
| 20:42.37 | g1powermac_PB | yea |
| 20:45.04 | g1powermac_PB | can't judge though how hard this would be from looking at the datasheet, as I've never done zigbee before |
| 20:45.55 | MonMotha | well, are you wanting to run *zigbee* or are you just wanting to chuck data around between a few nodes? |
| 20:46.29 | g1powermac_PB | well, at this point, just chucking data around would work |
| 20:46.33 | MonMotha | I don't know about the TI stuff, but the Atmel stuff doesn't even require you to run the 802.15.4 MAC, though it provides facilities to accelerate several functions of it |
| 20:47.25 | g1powermac_PB | the biggest issue is that TI provides a nice zigbee stack for these chips, but they're written for a non-opensource compiler |
| 20:48.03 | g1powermac_PB | and porting it to compile on sdcc could be just as problematic as just chucking data around |
| 20:48.48 | g1powermac_PB | also isn't 100% sure that TI provides the complete source to the zstack |
| 20:50.12 | MonMotha | Atmel provides a Zigbee stack, too |
| 20:50.24 | MonMotha | it's an AVR binary blob, unfortunately |
| 20:50.38 | MonMotha | however, their PHY driver and 802.15.4 MAC is OSS and builds with GCC |
| 20:50.48 | g1powermac_PB | thats cool |
| 20:50.55 | MonMotha | it's ridiculously overcomplicated, but source s available and builds with GCC |
| 20:51.04 | g1powermac_PB | is unsure what exactly TI gives |
| 20:51.17 | g1powermac_PB | I installed their windows tool on my dev machine |
| 20:51.21 | MonMotha | actualy, the Zigbee stuff isn't from Atmel, but Meshnetics (Atmel made a deal with them) |
| 20:51.26 | g1powermac_PB | and I see source code for the stack |
| 20:51.38 | MonMotha | that's one problem with 8051; there's no GOOD free compiler |
| 20:51.48 | MonMotha | the only free compiler I know of is sdcc, which is kinda blah |
| 20:51.54 | g1powermac_PB | how much of the code is there is another question |
| 20:52.12 | MonMotha | AVR uses gcc, which is at least decent, though it doesn't handle Harvard archs (like AVR) as well as it could |
| 20:52.42 | g1powermac_PB | I don't mind sdcc, I've used it quite a bit in the past |
| 20:52.56 | MonMotha | it's no GCC, though |
| 20:53.02 | g1powermac_PB | true |
| 20:53.30 | MonMotha | you could theoretically write pascal for your avr, if you want |
| 20:53.47 | g1powermac_PB | heh |
| 20:55.09 | g1powermac_PB | can you look over the TI datasheet for the cc2340 (which is the full datasheet for the cc2431) just to see how hard the radio will be to use? |
| 20:55.44 | MonMotha | I'm a little busy for that |
| 20:55.54 | g1powermac_PB | k |
| 21:01.17 | g1powermac_PB | wonders how hard it would be to part meshnetics openmac to the TI chip. . . |
| 21:02.04 | MonMotha | at that point, why not just use Atmel's stuff? |
| 21:02.27 | g1powermac_PB | because I kinda want to use these TI chips |
| 21:02.36 | MonMotha | ok... |
| 21:03.10 | g1powermac_PB | mainly because its everything on one chip and it has the location stuff |
| 21:03.37 | MonMotha | good luck the |
| 21:03.39 | MonMotha | n |
| 21:04.02 | MonMotha | we pretty much threw away that stuff because it was so ridiculously overcomplicated |
| 21:04.21 | MonMotha | layers and layers and layers of abstraction that serve no purpose and don't actually make it much easier to port to other hardware/platforms |
| 21:04.44 | MonMotha | oh, and function names that are, and I kid you not, about 120 characters long |
| 21:04.57 | g1powermac_PB | woah |
| 21:05.02 | g1powermac_PB | hmm |
| 21:05.25 | MonMotha | atmel makes fine hardware (well, in some cases), but their software tends to, well, suck |
| 21:05.30 | g1powermac_PB | well, guess I could use this: http://www.tinyos8051wg.net/ |
| 21:05.35 | g1powermac_PB | heck yea on that |
| 21:05.42 | MonMotha | fortunately, most of their hardware is so simple that you don't need their software |
| 21:05.49 | g1powermac_PB | is still grumbling over their fpgas I got |
| 21:05.58 | MonMotha | AVRs and the RF230 are both like htat |
| 21:06.16 | MonMotha | the RF230 is basically a state machine with a bunch of registers |
| 21:06.28 | g1powermac_PB | the tinyOS thing is interesting |
| 21:06.32 | MonMotha | actually, I shouldn't even say "a bunch" |
| 21:06.41 | g1powermac_PB | and it already works on the cc2430 |
| 21:06.52 | MonMotha | then have at it |
| 21:06.55 | g1powermac_PB | but I really don't want to learn nesC |
| 21:07.06 | g1powermac_PB | meh, anyway |
| 21:07.08 | MonMotha | then don't |
| 21:07.28 | g1powermac_PB | speaking of state machine. . .the TI chip does have one |
| 21:07.38 | MonMotha | we had a large-ish ARM7 running FreeRTOS already |
| 21:08.54 | g1powermac_PB | "CC2430 has a built-in state machine that is used to switch between different operation states (modes). The change of state is done either by using command strobes or by internal events such as SFD detected in receive mode. " |
| 21:13.49 | MonMotha | so it's likely a similar interface to the Atmel chip, then |
| 21:14.00 | MonMotha | it's a fairly "obvious" way of implementing a device like this |
| 21:19.01 | g1powermac_PB | it seems quite complicated to me, but I'll have to read further |
| 21:57.02 | g1powermac_PB | actually, it doesn't seem all that complicated, just that TI made it look complicated |
| 21:57.21 | g1powermac_PB | I should be able to do this right on the bare hardware provided without all the crazy stack stuff |
| 22:04.47 | g1powermac_PB | this should be quite interesting |
| 22:04.59 | g1powermac_PB | anyway, I need to get back working on the zipit first anyway |
| 22:05.18 | g1powermac_PB | which reminds me, anything new with the zipit, GPSFan? |
| 22:06.28 | g1powermac_PB | wonders if prpplague will be done with my zipit this week |
