Thread: Best Approach for data capture (rs232)

I find this document a valuable resource for Linux serial ports: Serial Programming Guide.

Thanks for the input Jim.

But how do I implement the code? For example the program I am trying to monitor is written in nesC so do I put the file in the same directory or do I integrate it in other coding programs.

The link I gave you would be for the PC running regular Linux. Not the Virtual Box tinyOs (xubuntos). The tinyOs has serial port routines available that you would program with nesC.

My ambition is to create a program that will automatically capture the data and create a file containing the data while streaming through rs232 cable (serial to usb converter) which is also connected to the base station at the other end.

Where do you want to capture this data? On a regular PC running a Desktop operating system? On your Virtual Box? What do you mean by base station? A simple drawing of your network layout would probably help.

I can see the packets/data streaming in the terminal.

Where is this terminal running? In the VB tinyOs ?

Sorry for being vague...

The base station device is for programming the motes(sensor devices), base station has rs232 serial port. I want to capture the data of the network infrastructure in real time via usb port.Using windows XP the terminal is in the virtual box tinyOS.

I dont think there is a need for a network layout but here is a few examples - MOTE-KIT4X0 MICA2 KIT & Lesson 6: Displaying Data on a PC.

I just want create a program in C to put raw data of each packet received from the serial port into a file. So I can keep them as records.


Thanks

The rs232 is the Texas Instruments kit correct? If so, I think its important to note that you do not need to do any actual SPI programming (write the drivers for it) because its built into it. I think what you're trying to ask is how do you read from the USB drive itself into your c program? Am I understanding that correctly?

Okay, theres a library in C for checking for connected devices. Check this out I know its in C++ but its similar and the library function is for C too:
