Other Parts Discussed in Thread: CC2520, Z-STACK

Hi,

I am using SPI communication between MSP430 and CC2520, now I would like to communicate with some sensor also uising SPI.Do I have to make changes in initialization of SPI and what should I change and add in ZStack code?

Thanks in advance.

    Hi Zivorad,

    You have to use another USI module to access to your sensor. You must configurate

    the USI to work with this kind of sensor.

    Ok, but how it would be done in Z-Stack code? Can you tell me a little bit more about how it should be implemented?

    Thanks for help Launix.

    Hi Zivorad,

    Sorry for the suggestion. I tried to answer your questions and I do not know how to remove it.

    I worked with an SDI-12 sensor. The communications protocol for this sensor is similar to RS-232. I could not use the source code from Z-Stack for this sensor. I wrote my own functions based on the microcontroller examples. There are two examples for SPI. This is the link: http://www.ti.com/litv/zip/slac151d

    I do not know if you can use the source code foro Z-Stack for you SPI sensor or device. The HAL Driver API.pdf has not reference to SPI protocol...

    A greeting,

    Juan Antonio
