Tool/software:
Hi there,
We use the NFC sample code: RF430FRL15xH_Projects_v1_5\RF430FRL15xH NFC Projects\RF430FRL152H
The sample code is modified that enables the timer_A0 and ISR counts the numbers.
CCSCTL4 = SELA_1 + SELM_0 + SELS_0; // Select VLO for ACLK and select HFCLK/DCO for MCLK, and SMCLK
CCSCTL5 = DIVA_2 + DIVM_1 + DIVS_1; // Set the Dividers for ACLK (4), MCLK, and SMCLK to 1
CCSCTL6 = XTOFF; // Turns of the crystal if it is not being used
CCSCTL8 = ACLKREQEN + MCLKREQEN + SMCLKREQEN; //disable clocks if they are not being used
TA0CCTL0 = CCIE; // Timer A0 Capture/compare interrupt enable
TA0CTL = TASSEL__ACLK + // Timer_A clock source select -> ACLK
MC_1 + // Mode control, Timer counts up to the value stored in TA0CCR0
ID_3; // divide 8
TA0CCR0 = 2000;
#pragma vector = TIMER0_A0_VECTOR
__interrupt void TimerA0_ISR(void)
{
nfc_sys_data.timerCnt += 1;
if(nfc_sys_data.timerCnt >= 1500) {
nfc_sys_data.timerCnt = 0;
}
}
And, the mobile phone contacts the RF430FRL152H with NFC.
The test scenario: mobile contacts for 60 seconds then off the RF430FRL152H for 30 seconds, repeatedly. (One loop is 90 seconds).
The image shows the current of RF430FRL152H.
The current drops for 60 seconds when the mobile contacts the RF430FRL152H
The current rises for 30 seconds when the mobile off the RF430FRL152H
It crashes after testing 13 hours.
Please help if something I misses.
The code is attached.
