Hi guys. I have a question that i have been wanting to ask for a long time now. I don't want to get anyone offended or anything like that, i have been = using Gumstix for some of my projects my self. I just have been looking on this mailing list for a while and i have = seen some applications in which a Microprocessor with 400 MHz is just = not nessesary.=20 Like for instance: GPS tracking. RC, Gyro tracking (with servos) Serial LCD connection. GSM applications. - Data transfer. I mean, take for example The Gallileo Baloon project, no offence, a nice = idea but why would someone need a 400 MHz processor to tell a Camera to = take a photo and send GPS coordinates with a GSM module ? Or people are playing with Robots that work on Servos (Like from Lynx = Motion) Mhy would someone need to go and set up a buildroot for a linux = environment so that he could move 6 - 12 servos in a sequence or = reacting to Gyro data ? I don't want to offend anyone and maybie most people use this machine = for better use. But for those who don't, Could you please explain why ? Maybie i don't know much about Hardware or if there is a reason that a = 200 - 400 MHz processor is needed then please explain that reason to me. Demetris Z. |

The gumstix was the smallest cheapest computer I found to date that has USB host (with the verdex) and the least power consumption. What is really wonderful is the documentation no other hardware I found has near the amount of info. For creative people there is nothing we can not do with our gumstix linux is so much easier to program than straight hardware and with USB there are limitless options. I would like a bit more memory though and usb2 :-) ooh and faster :-) I'm a resource hog :-P > Demetris Z. > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Splunk Inc. > Still grepping through log files to find problems?

There are so many different projects one can do with exactly the same hardware product. If one also has more experience with software development than hardware development, that's an additional argument. For me the alternative could have been using an Intel based PC running linux, but it wasn't possible because of the power consumption (and it would have been more expensive). So I really feel this gumstix product is filling a good niche in the market, and whether we're underserved or overserved probably depends on the exact product. Doing a webcam 'box' sending pictures to a webserver using GSM once every day may be overkill for gumstix, but it only took me three evenings to implement, which shows the power of this platform. I end up running the CPU at a lower speed though, cause I don't need the speed. I'm pretty sure a cheaper solution would have taken me longer to implement. I'm not sure if it'd possible to have an even cheaper linux based board that would run Linux. That could have replaced some low end solutions, but I'm not sure how much cheaper such boards would be. In my case I think the extra dollars for having a faster CPU was worth it, as I can then reuse the board for other stuff later. Best regards, Lars ------------------------------------------------- |

This kind of top-down reasoning makes perfect sense in the consumer electronics industry: first define the product, then select the cheapest possible hardware (or even develop your own if that means more profits). But hobby projects are more open-ended and platform-oriented. The guys who are investing in embedded Linux today will be able to easily upgrade their projects with real-time image processing, sophisticated networking, CPU-intensive math, fault tolerance, multimedia compression, next-generation servos and sensors, etc. Actually, industries with short product life-cycles tend to favor overspec'ed but future-proof platforms too. Looks how mobile phones have evolved in the last 10 years. Pascal |

Well reacting to the gyro data is a rather low level function. Things start to get interesting when you start laying on top of that.

I like the R8C/M16C/M32C family, because programming is simple (serial port and two GPIO) and the tools are free. To put a single R8C in a project costs a TOTAL of about $5. That's for C/C++/Asm, too. And the M32C family isn't unique; most MCUs are simple to program once the specs are available. For my furnace project, the TOTAL parts list for programming all five R8C chips from the gumstix was a single 8:1 analog mux to choose which R8C's Tx line was connected to the gumstix's Rx line. I build the flash images on my PC (free tools), scp those to the gumstix (I use that to support a web server, ssh, ntp, etc, plus run the master control algorithm), and the R8C programmer runs on the gumstix itself. |

I think another important thing to mention is that many shops aren't set up to manufacture BGA products. Development time is actually more expensive than *just* parts. You've got to pay an engineer's salary for every second of development time. An engineer's salary is just the tip of it too, because you have to stuff his health insurance account and pay up an unemployment account, pay for your own production costs indefinitely, etc.... Cheap, tiny form factor linux-ready sbc's are priceless in many ways. Who cares if it's overkill... even on the 600Mhz version you're still only clocking 2.5W. That's nothing to fret about.

The difference between say $30 for something slower that you have to learn some assembly language to program, and fight yourself to keep your program running inside a few kB of RAM, and a Linux system on which you can write python scripts above a full OS is huge in saved dev time for most people. |

Just a note on the UAV part of things.

The more often you can do this per second the more accurate = your flight will be." A solution as Gumstix is pretty optimum for a UAV only in a case where = you would test it and do your programming. When used in the field though it becomes a problem. The Main problem is the 60, 90, 120 pin connectors. Most UAV's are made with Petrol Engines (since they consume less fuel = and fly longer). When Gumstix is placed on top of for instance a Custom = Board or Robostix then when you start your baby up all those connectors, = parts start to shake off, get loose. Gumstix has to be pretty tight on = the PCB and probably allot of RESIN and other antivibration equipment = has to be used so that PCB stays safe and untouched. I had similar boards shake the hell out of them when a PPiston engine is = running.=20 I don't know about you guys but i haven;t figured a way to make those = connectors work yet.

I suspect that we can build the openmoko software for gumstix with openembedded fairly easily :) Philip Christian Faure wrote: > I've found this site > > http://www.openmoko.com > > Same things can be done with Gumstix + Goliath + LCD ? > > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Splunk Inc. > Still grepping through log files to find problems?

Not quite. With out even looking at it would be impossible. Because what you would be saying is that it would be possible to use a USB device without drivers and this is simply not possible. You need a full blown OS for most USB devices.

What the hell is that for? what good is a filesystem without an OS I'm not getting what its purpose is?

Obviously you have some misconceptions about things. Are you saying you can't write drivers without a full-blown OS? That's interesting I was unaware of such restrictions. I've written many drivers which don't use an OS. Talking to USB flash drives or USB HID devices (like keyboards and mice) is definitely possible to do without an OS. Atmel sells chips (AT90USB series) which comes with a USB host stack, and no OS. You can also easily interface many USB host controllers to 8-bit micros in order to talk to USB devices. Is it going to work with any old device you might think to plug in? No. But will it work with some devices - absolutely. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

No I know this but it seems rather pointless to me because you would need to do it for any type of device you want to use. It is like reinventing the wheel each time. The devices you pointed to can only read fat and only usb mass storage devices im not sure if you could plug in a usb cdrom or not. Doubtful because it doesn't talk about iso9660. And to support such devices you start to end up with something like hmm guess what a gumstix or linuxbios.
