[Tinyos-help] Fw: serial data reception on a mica2 mote fromanother microcontroller

[Giri Baleri]

Dipti,
 
It is hard to give you precise answers without understanding your NEC
micro controller.  In general, if it has UART type serial outputs, you
need to configure baud rate, number of bits, parity, stop bit and flow
control. Once you configure these parameters on the Mote UART, you would
then read the packets, decipher them and then put the relevant data
fields into the data payload of the RF packet.
 
Regards,
Giri

Dear Giri,
 
Thanks a lot for your reply.
 
I have few doubts about the XSensorMTS400 application, it functionally
captures data from various pressure, temp,humidity,light sensors nd
sends the data serially to Mica2 mote. For my application i have to
connect a NEC microcontroller with the mica2 . This NEC microcontroller
captures data from some external sensors which is 
digital and sends it to the mica2 mote over a serial connection. What
parameters do i need to take care of . Do i need to extract the data
from the serial packet sent from
NEC and then packet it in mica2 for sending the same over RF?
 
Apart from the baud rate compatibilty of the mica2 and the NEC
microcontroller. What are the other parameters to make communication
possible. Can i use The existing 
GpsPacket and other configurations inside XSensorMTS400.? What kind of
changes need to be done.. 
 
Please help me, it would be really thankful of you,
 
With Regards,
Dipti Jaiswal

	Dipti,
	 
	The XSensorMTS400 application (found under /contrib/xbow/apps)
has an interface to external UART serial device (GPS module). It also
has example implementation of interface to external I2C serial device
(Humidity/Temp sensor).

ensorMTS400/
	 
	This might be a good starting point for your application.

	Hi all,
	 
	I need to design an application wherein a mica2 mote .. say mote
1 receives data serially from another microcontroller and forwards it on
the Rf. I needed some guidance as to how can this communication be
established. How will i use the clock and other interfaces to suit
serial communication in this scenario.?
	Please help,
	 
	Thanks in advance.
