configuring/programming an rf module

Other Parts Discussed in Thread: CC2520, CC2420, CC2530, MSP430F5438

hi,

i'm doing an auto-learning on an rf transceiver module, as i'm not familiar with ti products. i'm using an msp430 microcontroller eb and an rf transceiver eb module using the 802.15.4 (i'm a beginner at the moment).

my question is, where can i find a step-by-step tutorial on how to programme an rf transceiver (notably on the 2.4 Ghz band) ? i've tried following the example codes without much success.

so far, my procedure for the transmission has been as follows (not working great though):

- init (for the ports, spi interface, rf module)

- interrupts (config, enable or disable)

- oscillator (start and wait till stable)

- set the source pan id and source address

- flush tx queue

- fill payload (just anything to receive)

- write everything to fifo (respeting the packet format and bytes: length, fcf, sequence, dest pan id, dest add, source pan id, source add, payload)

- initiate tx

- wait for ack (optional)

is my procedure generally okay ? have i missed out something important (okay, the brief summary above wasn't that detailed, so hard to tell right ?) ?

thanks a zillion !

Which 2.4GHz Transceiver are you using? The easiest way to getting started is to use the development kit mentioned in the product folder for the transceiver. Usually you will find User's manual which describes step by step how to set up a RF link.

I made the communication between CC1111 and CC430 on 434 Mhz.But now i want to made the communication between CC1110 and CC430on434Mhz.

for that i made the desired register changes through RF studio http://focus.ti.com/lit/an/swra352/swra352.pdf and build the project.In Iar tool i am replace the CC1111 by CC1110f32.I have done the changes in the FREQ2,FREQ1,FREQ0 through RF studio.

But the CC1110 and CC430 are not able to communicate?If you have any solution Please told mi for the proper communication of the CC1110 and CC430on434Mhz.

Thanks in advance

BR,

well, i'm actually using the cc2420, an outdated version of cc2520 i think, but with the 802.15.4 protocol.

by the way, there's not much of a user's manual for this particular module (http://focus.ti.com/docs/prod/folders/print/cc2420.html). i'm actually relying on the datasheet, which explains what each register's doing, and the blinking led example codes (which i can't make working).

thanks for advice.

Then its better to start with CC2420DK http://focus.ti.com/docs/toolsw/folders/print/cc2420dk.html

Manual http://www.ti.com/litv/pdf/swru045

If the intension is to use CC2420+MSP430 and develop Zigbee application then you can use CC2420MSP430ZDK http://focus.ti.com/docs/toolsw/folders/print/cc2420msp430zdk.html

But for new designs I would recommend CC2530 or CC2520+MSP430 platform.

well i have a cc2420emk together with an msp430f5438 eb, into which the cc2420emk slots just fine.

does that mean that it'll be hard for me to see where i'm going with these ? i mean, i've adapted the change of ports, etc...

i'm using cc2420 coz it's been around for sometime and is thus "established" and robust, whereas from what i've heard, the 2500 series (cc2530 included) are relatively recent... with all due respect of course.
