[Tinyos-help] Sensirion Tmote sensor

Hi, I noticed that the sht11 temp/hum sensor it is affected with self heat produced by the microcontroler. I measured the internal temp of TI msp430 and read 29 Celsius , the temperature read on sht11 is 27-28 Celsius and ambient temperature is 23-24 Celsius. I wonder if the sht11 is glued in

[Tinyos-help] bug in MSP430TimerM and MSP430TimerP

Hi, I tried to use the inputdivider function to set the prescaler for the timer and it didnt work. I check the implementation and I believe I should be change from async command void TimerA.setInputDivider( uint16_t inputDivider ) { TACTL = (TACTL ~(ID_1|ID_3)) | ((inputDivider 8)

[Tinyos-help] problem with UART com and Radio msg

Hi, I have problem when sending RF msg and continously talking to a digital sensor conected to UART0. The problem is that I receive bad crc packets, when transmiting, in a rate of 10%. If I disable de UART interrupts before sending and then enabled once sendDone , no bad crc msg appear. Does

[Tinyos-help] interrupt vector numbers

Hi, why does in mica2 the interrupt vectors numbers are 1 less than in the Atmega128L.pdf datasheet. e.g. interrupt vector for SPI serial transfer complete, listed as 18 in the datasheet, is declared as 17 in iom128.h -Bill ___ Tinyos-help mailing

[Tinyos-help] many lost packets mica2

Hi, I had a mica2 conected to a digital oximeter through the UART0. The baudrate of the conexion is 4800 baudrate and the sensor sends data at a rate of 1920 bit/s (60 packets per seconds of 4 bytes each one). I merge sensor data into a TOS_Msg packet, and when it is full I send it over the radio.

[Tinyos-help] many lost packets mica2

hi I had a writing mistake in my previous mail. I pretty sure it is not a software problem. -Bill ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help

[Tinyos-help] UART0 SPI CC1000

Hi, I dont understand if the prog_miso/mosi pins are the ones used for CC1000 SPI comunication with the micro in Mica2. I want to know if there is a problem in using UART0 and send/recv radio messages since it seems to share hardware lines. thanks, -Bill

[Tinyos-help] problem with getContinuosData()

Hi, i have problem sending messages when using getContinuosData(). Everything looks like if it works, i mean i get the sendDone event with success result, but nothing seems to be going out the radio. I saw someone post the same problem, but got no answer, thanks in advane, -Bill

[Tinyos-help] change ADC reference on Mica2

the actual ADC reference on Mica2 is the supply voltage (3.3 V),isnt it?. Is it posibble to change this reference value, without mayor hardware changes. Cuase I wanted to measure voltages in the order of milivolts and I am thinking in a reference voltage like 10 mV. What would be the answer in

Re: [Tinyos-help] __attribute((packed)) on msp430

Hi, the network types are nx_ or nw_ ? http://nescc.sourceforge.net/networktypes/network-types.txt thanks, -Bill The msp430 requires 16-bit aligned addresses for 16-bit operations. In the MSP430 x1xx User's Guide, Section 1.4.5 RISC 16-bit CPU, Instruction Set, Memory Organization,

[Tinyos-help] telos acknowledge

Hi, I have a question related to system layer acknowledgement on telos motes. I did a few experiments to understand what happen when one enables the Mac.ackEnable(). The interesting thing I found is that when a mote send a message, with the Mac.ackEnable(), to other mote (direct addressing,
