[Tinyos-help] TOSThreads BaseStation demo (2.1.2)

I have not had success using TOSThreads to write to the Uart interface. So, I devised the following test. Using tinyos-2.1.2 distribution, I performed the following test with two telos motes: cd apps/tosthreads/apps/RadioStress make install,1 telosb threads bsl,/dev/ttyUSB1 The mote's led's in

why are you using tosthreads? On Thu, Feb 13, 2014 at 11:12 AM, Stephen Schaub wrote: > I have not had success using TOSThreads to write to the Uart interface. > So, I devised the following test. > > Using tinyos-2.1.2 distribution, I performed the following test with two > telos motes: > > cd

Eric, I am researching TOS threading approaches. I thought I would start with tosthreads since it is included in the distribution. On 2/13/2014 10:42 PM, Eric Decker wrote: why are you using tosthreads? On Thu, Feb 13, 2014 at 11:12 AM, Stephen Schaub > wrote:

tosthreads isn't being actively maintained. and it sounds like you have found a bug. so you will probably have to debug it to figure out what is going on. do you have an environment where you can actively observe the machine state? ie. a jtag environment? On Fri, Feb 14, 2014 at 4:41 AM, St

Thanks for the info about tosthreads not being maintained. That's helpful to know. I would be interested to know if there are any competitively multithreaded solutions for TOS that are being actively supported. Stephen On 2/14/2014 2:33 PM, Eric Decker wrote: tosthreads isn't being active

TinyOs is a low level event driven embedded OS. Predominately applications use a combination of interrupt level and the TinyOS task level which is the middle layer (tosthreads is a lower background layer). I am not aware of any other threaded implementations that are equivilent to tosthreads. th

Re: [Tinyos-help] TOSThreads BaseStation demo (2.1.2)

I am doing pure research on TOS threading solutions. There is no particular application at the moment. I was drawn to tosthreads as a reference threading solution because of its inclusion in the distribution, but ran into trouble when developing a test application with it. I am relatively new

There's also Ocram: https://github.com/copton/ocram Make sure you read the paper at http://www.vs.inf.ethz.ch/publ/papers/bernauer_ipsn2013.pdf Janos On Fri, Feb 14, 2014 at 3:11 PM, Stephen Schaub wrote: > I am doing pure research on TOS threading solutions. There is no particular > applicat

Re: [Tinyos-help] TOSThreads BaseStation demo (2.1.2)

Janos, I'm aware of Ocram. I believe it is a cooperative multithreading system, and doesn't appear to have been updated in a year. Do you know whether anyone is actively using it? Stephen On 2/14/2014 4:37 PM, Janos Sallai wrote: > There's also Ocram: > > https://github.com/copton/ocram > > Ma

Hi Stephen, I'm the author of Céu [1], a Esterel-based language, which appeared in SenSys last year [2]. It is mostly cooperative ("synchronous" would be more accurate), but with support for time-consuming asynchronous execution (not in the paper). Not intended for hard real-time systems, though (
