    A couple of years ago we purchased a CC2430ZDK. After spending most of this week struggling to get the example programs built and downloaded to either the SmartRF04EB+CC2430EM or the CC2430DB, but when I try to run the TIMAC sample program, I just get the two connected LEDs blinking together, forever...

    Hi OldBoy, does your prototype board use the same VDD as SmartRF04EB (3.3V)? If not, make sure you have a strap from your external prototype to the level converter on the SOC_DEM (if you have this plugin-EM, this is preferred) or the P14 SoC Debug header (pin 2) in order to convert the voltage levels...

    I tried to make the board work using the two possibilities ( 3.3V from the SmartRF04EB feeding the board and external voltage source) and none of them succeeded. I tried to enter debug using the P14 connector and the SOC_DEM. All conections from the external prototype to the SmartRF04EB are following...

    Exactly. I keep getting "Chipcon SRF04EB \n No EM detected" on the lcd of the SmartRF04EB. I've checked the ground many times and it seems to be ok. And the DD/DC/RESET_N signals are ok ( 3.3V in all of them). As I also have no more ideas, decided to do a last try. I picked up a fresh...

    Hi guys, Thank you both! After renfab said he had the same problem, I decided to test my board once again. But now, I checked the pin 2 on P14 and saw that its voltage level didn't reach 2V! Then I wired it up directly to a 3.3V point, and it worked! The problem was in the board track that...

    Kjetil
    Hi There. The CC2430 was downgraded from 14 to 12 bit based on characterization results. It's still the same ADC and that's why there is a 14-bit data register. The datasheet remains to be updated in regards of these registers. No matter what resolution of the ADC one uses, the msb of the result...

    Hi jorge, TI currently do not offer any alternative smaller/cheaper hardware for flash programming of CC243x devices other than the SmartRF04EB. However, there are some third party alternatives .

    On the PHY level 802.15.4 use a DSSS modulation scheme which offers very good robustness. Only the 802.15.4 radios offer this modulation. Above the PHY layer a device like cc2520 adds significantly more advanced protocol offload capabilities than cc2500. While this is tailored to the 802.15.4 MAC layer...

    Chris, Thanks for the reply. You got me thinking that I should spend a little more time reviewing the CC2xxx documentation. I had looked at the TI CC2430/CC2591 reference design and it shows an almost direct RF signal connection between the two components; no matching network components required (except...

  • Forum Post: Re: What is the appliaction difference of CC2430 ; CC2480 ; CC2520? How much improvement can CC2591 make?

    sverreb
    The cc2480 needs an external MCU to run your application. It will run the stack on it's own (So you can use a smaller MSP than you can with the cc2520). The cc2430 enables you to run your own code along with the stack with no external MCU, but you must share resources with the stack.

    This indicates a connection problem between the CC2430EM and the SmartRF4EB. The PC software indirectly communicates with the CC2430EM via the CC2430 Debug interface. The symptoms you describe suggests that one of the 2 debug lines are broken. The best way to test this is to reprogram the CC2430 with...

    My design includes the CC2430 with Anaren Balun connected to Inverted F Antenna (DN0007). Since the impedance of the antenna and balun are both 50 ohms, can the antenna feed point be connected directly (within 0.2mm) to the balun pad without using 50 ohm PCB transmission line?
