TRF7964A: Using TRF7970ABP_RFID_Reader_Demo code

TRF7964A: LaunchPad (MSP-EXP4302ET) and TRF7970ABP_RFID_Reader_Demo code

Hi Andreas,

I received the LaunchPad (MSP-EXP4302ET) and am able to load an run the TRF7970ABP_RFID_Reader_Demo code, but it does read any tags.

The code seems to be stuck at this line:

void TRF79xxA_waitTxIRQ(uint8_t ui8TxTimeout)
{
g_sTrfStatus = RX_WAIT;
g_ui8TimeoutFlag = 0x00;
while((g_sTrfStatus != TX_COMPLETE) && (g_sTrfStatus != TX_ERROR))
{ // Wait for end of TX
// Clear the IRQ Flag
g_ui8IrqFlag = 0x00;
// Setup for the Timer
MCU_setCounter(ui8TxTimeout);
while((g_ui8IrqFlag == 0x00) && (g_ui8TimeoutFlag == 0x00)) // Wait for an interrupt
{
// Do Nothing
}
RESET_COUNTER;
if (g_sTrfStatus != TX_COMPLETE)
{

......

Maybe I need to do something on the launchpad with one of the jumpers or something?

Thanks, 

Becky

    Becky,

    as discussed in the call today, the DLP-7970ABP was missing to make the demo setup complete. The DLP-7970ABP will be connected on top of the MSP-EXP430G2ET.

    That's how the complete setup will look like (please note the orientation of the DLP-7970ABP on top of the launchpad).

    Please try again once you have the DLP-7970ABP.

    I will close this thread for now.

    If necessary you can still post related questions here or open a new thread.

    Best regards.

    Andreas.
