[Tinyos-help] TelosB UART bug
Greetings all, I am currently using TinyOS 2.x and TelosB motes, I tried to write data to the UART pins on the expansion header which gets converted to RS232 through a conversion kit I have so that I can see the data output on hyperterminal. However, I am not seeing anything on hyperterminal. I used UartStream.send to send data to my UART pins, when it is idle (not sending) UART TX pin showed constant 0V. When signal sent, 0V to 3V square waves are shown. Correct me if I am wrong, when UART is at idle stage, shouldn't it be constant 3V? Another question...I measured voltage at the UART pins using the scope, I see square wave signals, then I probe pin 2 of the female DB9 conenctor on my conversion kit, I am seeing 8V to 0V square waves, so I conclude that I am getting signals through hardware but for some reason I am not seeing anything not even garbage on hyperterminal, any hints?? This is urgent and any help will be appreciated...

[Tinyos-help] Uart Radio TelosB
Hi all, I am a college student working on a design project, I am currently trying to modify the Blink program such that upon receiving radio packets, I will write data to the UART0 pins. I have a few questions because my code doesn't seem to be working right: I am using TelosSerialP.nc, PlatformSerialC.nc, Msp430Uart0C.nc, Msp430Uart0P, and BlinkToRadio. Question 1: I read something about shared resources for UART and Radio for TelosB, is it true that I have to turn off the resource for UART while waiting for radio packets and turn off the radio control for UART writing? If so, Resource.request() and Resource.release() will do? Question 2: I am using UARTStream to write data to the UART0 port, I might have some wrong settings on hyperterminal but I am not seeing anything. However, I do see signals on the oscilloscope although I don't know how to interpret them. For example, I do UartStream.send(1010, 4) That should send raw data 1010 string to the Uart0 is that correct?

[Tinyos-help] Serial Communication in C
Greetings, I am a newbie currently working on a project which uses TelosB motes to send packets back and forth. Now I am connecting one of the motes to an another microcontroller through UART - RS232 connection. Now the question is, I want the microcontroller to be able to call command moteIF.send() similar to the java version one to send packets back to the other mote. I used the java version and I manually turn on the serial forwarder with the right ports to run the application (on a PC). However, I will not be able to do the same for this microcontroller since the microcontroller is not connected to a PC at all. My question is how will I be able to achieve that? Upon receiving packets from the other side, I want the microcontroller to call the send function to the connected mote and send packets back. Any help will be appreciated, Thank you in advance... _ Make i'm yours.

[Tinyos-help] UART
Hi, I am a college student and I am new to TinyOS. I am current using version 2.x of TinyOS. I wrote a program which sends radio packets from one telosb mote to another. However, the second part of my project is to forward the received packet to another microcontroller through UART. I read something about GenericCom and send data to destination: TOS_UART_ADDR but I am still confused about it. Is there a tutorial available which teaches me how to write data on the UART pins on the telosb and flush them to the other side? or anything that can give me a hint on how it can be done. Thanks!!

[Tinyos-help] TinyOS Keyboard Input
Hi Everybody, I am a student and I am new to TinyOS. I went through the tutorials and I notice that TinyOS provides a printf function just like C. I am trying to implement a program which takes keyboard input from the user. Is there a scanf function which I can use to do that? If not, any other alternatives which I can do to provide the same operations?
