Hi, I have been looking for some open source software for a serial to ethernet gateway for transmitting sensor network data over IP, via a serial port. That's how I came across the ODDAS project page on sourceforge.net. ODDAS looks quite promising to me and I plan to download it and check it out. But, I was wondering if any of you could tell me if ODDAS would work on any flavor of linux? If not, what are the recommended linuxes for it? Would appreciate any comments or suggestions. Thanks, Arun. |

Dear folks - Now that I have been axed by SuSE, I have decided that it is no longer a big deal to try to get this thing to compile using anything but the x86 architecture. So I am going to go through the build script and assume a compile using the native tools on a x86 instead of a separately installed development system. If this throws a wrench in anybody's plans, please let me know so I will stop. -Pete- |

Dear folks - After scanning the web for a bit, I have decided to investigate the AVR microcontrollers a bit. They look pretty spiffy. New RISC architecture, optimized for use with C. Every one has flash on it, none of this EEPROM or OTP stuff. Cheap, too. The downside is, I do not see one with CAN built in. But maybe we could live with a separate CAN controller chip. -Pete- |

Dear folks - If anybody out there is listening, just thought I'd tell you what I'm thinking about for ODDAS-Linux. I'm going to change around some of the packages, thought it will increase disk use. For example, I have now used ash enough to really hate it. I think 300K more for bash just may be worth it. And then I can steal a lot of the initialization and configuration scripts for SuSE Linux, thus making it more flexible. Any comments? -- Pete Buechler Developer, SuSE Labs pe...@su... http://www.suse.com/~peterb |

Hi Axel, The HC12 is certainly a possibility for the sensor modules. I assume you can get the usual selection of A/D, D/A, digital I/O etc. on those parts, right? Aren't they supposed to be the upgrade from the HC11? Anyone know what happened with HC16? I did my previous automotive data acquisition with those parts. As for PC interface w/ CAN, I haven't really looked into it. Could you do a search and come up with some options? -tim Axel Hertling wrote: > Hi, > > just like to introduce myself. > > Note that the MC68HC912BC32 and MC68HC912D60 members of the HC12-Family > seem to have CAN interfaces. > > It´s not the HC11 but i don´t worry since i know only the HC12. > > The GNU Tools seem also be ported to the HC11 / HC12. > > Does anyone have references for cheep CAN cards for ISA or PCI and CAN > modules ? > > > Greetings, > Axel > > _______________________________________________ > Oddas-develop mailing list > Odd...@li... > http://lists.sourceforge.net/mailman/listinfo/oddas-develop > > > |

Hi, just like to introduce myself. Note that the MC68HC912BC32 and MC68HC912D60 members of the HC12-Family seem to have CAN interfaces. It´s not the HC11 but i don´t worry since i know only the HC12. The GNU Tools seem also be ported to the HC11 / HC12. Does anyone have references for cheep CAN cards for ISA or PCI and CAN modules ? Greetings, Axel |

Looks great! Thanks Pete. I'm really sorry I haven't been as active as I first anticipated. I have some designs of old 3-d accelerometers using ADXL05's and some other stuff using the PIC14000 (a cool analog/ digital mix chip). I want to revive those and get them up on source- forge.

Dear folks - I have finally gotten ODDAS-Linux loaded into our CVS tree. I also created a new module for it and released it. Then I posted news about it. I have also set up a project web page, take a look at http://oddas.sourceforge.net. I hope these efforts meet with your approval. -- Pete Buechler, SuSE Labs pe...@su... http://www.suse.com/~peterb |

Good questions. I see it in a similar light also. While my original goal for this project was automotive data acquisition, I knew from the outset that Linux was over- kill. I just wanted to do it. RTEMS or ECos are better suited for smaller embedded systems. If ODDAS evolves past automotive then so be it. Speaking of wireless - absolutely. I have a friend that owns Racing Communications (http://www.racingcommunications.com/) who is interested in wireless data acquisition via the data channel of his various voice radios. Do you guys get Embedded Systems Programming? (http://www.embedded.com/) - hit the magazine link. Its free if you qualify (just lie). They have an article on Bluetooth this month, but I haven't read it yet. Its on the web site: http://www.embedded.com/internet/0007/0007ia1.htm -tim > -----Original Message----- > From: odd...@li... > [mailto:odd...@li...]On Behalf Of Pete > Buechler > Sent: Thursday, July 06, 2000 11:21 PM > To: ODDAS developer list > Subject: [Oddas-develop] What we want from Linux > > > Dear folks - > > Just what do we want from Linux in ODDAS?

Dear folks - Just what do we want from Linux in ODDAS? I guess I kind of saw it as a central point to gather all the data and log it. For systems where a network is available, it could provide updates on status and statistics to other machines. But what about applications where a wire is not practical, such as robotics or automotive? We could store up the data and then download it when the machine gets back to a shop. Or what about wireless? I know IEEE 802.11 is supported under Linux, but that only has a range of 250 feet. I could see that being very useful for a mobile robot, but I guess an automobile would need a bit more range. -- Pete Buechler : SuSE Linux Developer Work e-mail : pe...@su...

Dear folks - Since we all agreed that smallnet was not small enough, I have put together another system, called tinynet. It takes a bit more than 3M of disk space, but still has ftp, telnet and http servers.

I noticed that about Microchip. I love their stuff, but a two chip solution seems a little much, unless the cost is still justifiable. I think Motorola has a HC08 with CAN in it too. BTW, if anyone is wondering (and this is more for the list archives), we are looking at CAN and/or J1850 because of it noise immunity. SPI, serial, USB, etc. were not designed for the types of environments that I see ODDAS being used: car engine bays, chassis', industrial machinery, etc. -tim Pete Buechler wrote: > > Guys - > > I just surfed over to Microchip.

Guys - I just surfed over to Microchip. They have a standalone CAN controller that can interface to just about any microcontroller, but I did not see a microcontroller with CAN built in. But at a trade show recently I stopped at the Phillips booth and saw the 8xC592 at work. A reference to Phillips CAN microcontrollers can be found at: http://www.semiconductors.com/can/news/backinbusiness.html Another thing that these controllers have is tons of stuff on board, such as A/D, discrete I/O, and even PWM outputs (maybe good for motor control). Of course, this assumes that CAN is the way to go. I thought about maybe using USB, just because it will probably be very cheap, but it is a polled protocol. I guess CAN is what we want. -- Pete Buechler : SuSE Linux Developer Work e-mail : pe...@su... Work web page : http://www.suse.com/~peterb Personal e-mail : pet...@ho... |

The July issue of Linux Journal has a brief article on embedded and real-time linux. They list many variants (but not all). Worth looking at. It isn't online unfortunately. -tim |

Is that with or without the X-server? also check out ELKS: http://www.elks.ecs.soton.ac.uk/intro.php3 these folks have already done something similar to what we are doing: http://www.esrf.fr/computing/cs/sysadmin/rtk/emlinux/pc.htm and I'd be willing to bet the RedHat/Cygnus will be coming out with an EL/IX compatible version of embedded linux soon. Keep your eyes out here: http://sourceware.cygnus.com/elix/ I haven't kept up with the latest FLASH/SRAM prices, but they will help dictate our memory requirements. I don't want to have to pay $50 for 8M FLASH chips if I can get away with $10 1M chips. But if it's much cheaper now, then let's go for it. Good work Pete, keep up-to-date with these goings-on. I've been slammed for the last week with some side work and I'm about to be slammed for the next 1.5 weeks on my real job. I'm working on dishing off some of this work so I can start testing some of the embedded linux solutions on my old machines. Please be patient with me and feel free to run with your ideas. -tim Pete Buechler wrote: > > Hi all - > > Just thought I would update you on my hunt for a small Linux. It might already > be done.

Hi all - Just thought I would update you on my hunt for a small Linux. It might already be done. At the site http://www.linux-embedded.org there is something called LEM-Linux. It is about 4M, though.
