RF430FRL152H: The programming of the RF430-TMPSNS-EVM

Part Number: RF430FRL152H
Other Parts Discussed in Thread: MSP-FET,

Hello,

I buy the RF430-TMPSNS-EVM, EXP7970ABP and EXP430g2ET. At first, the distance between the RF430-TMPSNS-EVM and EXP7970ABP is about 5cm. However, my project is to enlarge the distance to 1m. So I want to programming the RF430TMPSNSEVM and connect the additional power source. Now the first question is that which pin I need to connect when I want to programming the device? Second one is that should I need a debug tool when I programming it? 

   

The last question is that is this tag has semi-passive function?

    Hello Zihong,

    NFC technology is not well suited for 1m, and our RF430FRL152H is not intended for that range. There are a few applications which can do 1m with NFC but they require large hardware setups and a lot of power. In reality that design is not intended to be used beyond 10-15 cm in a very optimized setup.

    Hello Ralph,
    Yes, I understand. However, by using the protocol ISO15693, the maximum distance is about 1meter.
    So one more question I have is that which port I need to connect with when I programming it. And should I buy a debugger device?
    Best regards

    Hello Zihong,

    That patch is not really designed for debug, but if you need to connect to it for debugging then you'd need level translators for all JTAG lines and you'd connect to the 6 pins starting at TP15 and going down to TP3 to your programmer which would be an MSP-FET.

    I would recommend all debug be done on the RF430FRL152HEVM and then use the Over The Air programming feature in our RF430FRL152HEVM GUI to program the RF430-TMPSNS-EVM patch instead of trying to connect a programmer to it.

    Hello, Ralph,

    I try to programming the tag over the air. However, the GUI can not write to the device and read from the device. I don’t know how to reset the tag.

    Best regards.

    Hello Zihong,

    This is why I said we recommend all debug be done with the RF430FRL152HEVM... you probably overrode the ISR vector table and the chip can no longer be functional over RF until properly reprogrammed. You'll have to try and attach a debugger to it with the method I described previously.

    Please save yourself a lot of trouble and get a RF430FRL152HEVM for your development, you won't run into such issues with it.
