Other Parts Discussed in Thread: DLP-7970ABP, MSP430F5529, TRF7970A

Hi,

This is Regarding the NFC Card Emulation example program provided
in the below application note.
http://www.tij.co.jp/jp/lit/an/sloa208/sloa208.pdf

The example works properly with MSP430F5529-EXP-BOARD but doesn't work
with MSP430F5529-LAUNCHPAD.

Has anyone tried DLP-7970ABP+MSP430F5529-LAUNCHPAD?

Have tried both
1.Program the HEX file
2.Program through CCS debug(MSP430F5529-LAUNCHPAD mode)
Both doesn't work.

DLP-7970ABP jumper1 is in position 1.

ISO15693 LED is always OFF.

Best Regards.

    Kummi - 

    check out the build option in the CCS project itself and 

    and then also in the folder where the project was installed there is a launchpad folder where compiled .hex and .out files are located.

    the installer puts them here ==> 

    C:\ti\msp430\TRF7970A_CE_1.00.14\MSP430F5529_NFC_Card Emulation_Demo\MSP430F5529_LAUNCHPAD

    Kummi,

    I looked into the issue further and it seems there is a problem with the .hex and .out files for the project which were included with the installer. Update: When Flashing the .hex and .out files make sure to power cycle the board, both should work fine then. They will not work without the power cycling first.

    The CCS project that is included does work correctly when the Launchpad build option is set as Josh illustrated in the post above as well.

    And as a side note, when working correctly the ISO15693 LED will not turn on until an NFC reader is presented to read the tag information.

    Thank you Ralph and Josh,

    I was able to run the program correctly with your suggestions.
