How do you compile code for the DSP on the gumstick? I have only seen where you have to use code studio or code composer or some kind of IDE with complier and it costs quite a bit of money unless you…Continue

Colin Johnston replied to Senior Design 2010's discussion Ardupilot Code question"PID control loop gains are tuned for a specific response for a specific type aircraft but can accommodate some variance while still proving good control and stability. It is very possible that if you change the plant parameters, then you'll…"
Colin Johnston commented on Chris Anderson's group ArduCopter (traditional heli) user group"Does any body know how the fast the execution rate of the Ardupilot or Arudcopter software is the with current build without adding more code?"
Colin Johnston commented on Jordi Muñoz's blog post ArduIMU V3 ready for pre-order and check our new color!"You guys need to relax with the price issue. Whats 18 dollars...Come on already , this is all open source hardware and software..What more do you want"
Colin Johnston replied to Randy More's discussion Crazy question, could ArduCopter hardware and firmware be used in an ROV ? in the group ArduCopter User Group"Yeah, I think so. I did a small literature review on underwater controlled vehicles..You can find them on IEEE website if you have access to them. Many are alsoon the Internet free to look at."
Colin Johnston replied to Randy More's discussion Crazy question, could ArduCopter hardware and firmware be used in an ROV ? in the group ArduCopter User Group"Randy, with some modifications to the software and possibly hardware, it can be done. An IMU can certainly work underwater to provide body rates of your ROV. Again you would want to convert these body rates to something in an inertial frame. There…"

Jeremy replied to Colin Johnston's discussion Gumstix DSP"quick and easy answer is yes DSP works and can be compiled. You use bitbake to compile everything for your gumstix. Most if not all of your questions your asking would be answered by reading the gumstix manuals and openembedded"
Michael Zaffuto replied to Colin Johnston's discussion Gumstix DSP"Hi Colin, I'm not an expert or anything, but my understanding, from the information on the pixhawk site is that a PC running as an Ubuntu Linux Host can be used to compile both processors..for free. The C6000 compiler is seemingly offered for…"
Curt Olson replied to Colin Johnston's discussion Gumstix DSP"So what would I do with a DSP if I had one? (To abuse an old wizard of oz quote.) I know that's a dumb question, but I've never played around with a DSP before. Is it just another general purpose processor that can run whatever code a…"
Colin Johnston replied to Colin Johnston's discussion Gumstix DSP"Jeremy thank you for the email. I guess what I was looking for was not all the details of compling, building and so forth but if indeed one can compile code for the ARM co processor and the DSP all under my ubunto linux desktop without needing a…"
Jeremy replied to Colin Johnston's discussion Gumstix DSP"you DO NOT want to setup your build environment on a windows host, the only way technically I know of doing that would be adding cgywin or whatever its called. You will want to setup a linux box that will have your build environment on it. You will…"
Colin Johnston replied to Colin Johnston's discussion Gumstix DSP"I was reading that. So does this mean I don;t need code composer IDE with the C6000 complier for windwos? If I choose to do everything on a linux (ubunto) host? Im not very family will all the toolchains.
I want to build/compile files for both ARM…"

How do you compile code for the DSP on the gumstick? I have only seen where you have to use code studio or code composer or some kind of IDE with complier and it costs quite a bit of money unless you get the free version which is basically a student version and limits the amount of code you can complie. Is there any easier way to use the DSP on the Overo gumstix. I would hate to spend the $400 and not be able to use the DSP?Help..Does anybody know the steps to compling the DSP code and using…See More
