Re: [Tinyos-help] ADC Readings and VoltageC
Michael Schippling ha scritto: Did I ever ask what TOS version you are using? Yes, I'm using TinyOS 2.1.0. The only work I did with Iris was using MoteWorks which is the Xbow/Memsic system based on T1. I didn't use any regular ADCs, so who knows... Presumably they would have ADCs working correctly. Just for the heck of it I have zipped up the ADC sections of the Moteworks atm1281 platform here: http://www.etantdonnes.com/Motes/atm1281_adc.zip Also I wonder if the Vref is not right. According to my cheat cheat it should be on pin 2 of the connector and pin 62 of the controller. Thank you Michael! Now I take it.

[Tinyos-help] Compile Problem - Configuration File Being Ignored
Hello, I am having a compiler problem that I'm hoping someone can shed some light on. I have a configuration file that doesn't appear to be getting included in the build. This configuration file is in the same directory as a module file that is getting included in the build. I know the module is being included in the build because the compiler is complaining that some items are not connected. These not connected items have connections spelled out in the configuration file. I can create syntax errors in the configuration file that would normally cause the compiler to throw a fit, but not in this case. The names of the module and configuration files are HPLUSART1M.nc and HPLUSART1C.nc so they are valid file names (the compiler appears to ignore files with extensions it does not use such as .txt). These files do not exist anywhere else in the directory structure. Note, I am new to TinyOS and the XubunTOS development environment. Any idea what is going wrong? Thanks, Scott ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

Re: [Tinyos-help] Question about IRIS mote using OC3A,OC3B,OC3C
Hi Sofia! On Fri, Jan 28, 2011 at 1:31 PM, sofia aparicio aparicioso...@hotmail.com wrote: Hello, I finally I could see the output signal for OC3A, OC3B and OC3C. To do that I have to remove the TimerMilliC from my main program, otherwise only OC3A was working. Do you know why is that? OC3B and OC3C correspond to INT0 and INT1. Maybe this timer is using the interrupts? I have no idea why the TimerMilliC interferes with Timer3. In the documentation I could not find anything. I have configured them in Fast PWM TOP=OC3A and clear on compare match as follows: TCCR3A=0xAB; TCCR3B=0x9; So you have used COM = 2: clear on compare, set on bottom WGM = 7: fast pwm 10 bit So I think your top is not what you think it is (or maybe I have again misread it). OCR3A=0x3E8; OCR3B=0x5B; OCR3C=1; Removing the TimerMilliC from my main program I can see that the frequency does not change for each OC3 but the wide of the signal change. This is completely normal operation. PWM is used to change the set/clear distribution, not the frequency. If you want to do different frequencies, completely independent of each other, then you have to do is manually. Probably this would work: 1) Use WGM = 0: normal operation, keep the counter free running 2) Use COM = 1: toggle the pins on compare match 3) From the compare interrupt always update your compare registers by advancing it by 0x3E8 and 0x5B. I am affraid that you would not be able to get 0x1, that is just the clock right? The timer would not even be able to provide that frequency. If I remember correctly, then it needs 3 or 4 cycles minimum. Even the 0x5B is a border line case, since then you have to have a lot of interrupts and the MCU might not be able to handle those. Another option would be to use Timer3 and Timer1 together (and then you have to disable all other use of Timer1, e.g. radio driver) Best, Miklos Best, Miklos It is not possible to obtain different frequencies? I enclose you a picture of the results obtained in OC3B and OC3A. Thank you very much.

You cannot be sure that these pins are available on the 51-pins. I am using a MDA100 sensor board connected to my IRIS mote. I can see the signals in OC3A, OC3B and OC3C using an oscilloscope. You can see the pines in the 51-pin connector of the IRIS mote. Ok. You should try to enable the interrupts and toggle LEDs just to be sure that the problem is not a 51-pin connector wirings. As far as I know, OC3A = PE3 = PIN26, OC3B = PE4 = PIN6, OC3C = PE5 = PIN5. TCCR3A=0x57; COM3A = 1: toggle pin on compare match COM3B = 1: toggle pin on compare match COM3C = 2: clear pin on compare match WGM3:10 = 1 TCCR3B=0x19; ICNC3 = 0: input capture noise canceler disabled ICES1 = 0: input capture falling edge CS3 = 1: clock running with no prescaling WGM3:32 = 3, therefore WGM3 = 0xD: reserved. This is not OK COM3C=1: toggle pin on compare match. WGM3=0x0F; Fast PWM mode with OC3A as TOP value. Oh, you are right, I was tired apparently. I think that the configuration is OK. Can I use this Fast PWM and to use the tree output compares? Or do I need to use the CTC mode? Ok, now since you are using Fast PWM (I thought that you used CTC), then Table 17-4 of the datasheet says that COM3X = 1 means that OC1A toggles the pin but OC1B and OC1C are disconnected! You might want to use another mode of operation (WGM or COM). By the way, the Atmega1281 has timer 4 and 5 as well! If possible, I suggest you to use Timer/Counter 4 or 5, as no other code uses that (Timer3 was used instead of Timer1 on the MicaZ and Mica2 motes ,so there could be codes that uses that) I did not know, but the problem is that I do not have these pines available in the MDA sensor board (or in the IRIS connector). Yup. Best, Miklis Thank you very much. Sofia ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

Hello Shivasankar, You can read the RSSI by using the RSSI Demo application which is available in TinyOS. I am using TinyOS 2.1. However, I don't know about your version. But in my version, you can go to RSSI Demo from: tinyOS folder ---apps--tutorials---RssiDemo. In addition, you can learn about using it in these excellent tutorial on tinyOS website: http://docs.tinyos.net/index.php/TinyOS_Tutorials ans this link is for the RssiDemo http://docs.tinyos.net/index.php/Rssi_Demo Good Luck !
