MSP430F5529: RTOS TIMER Control

Yale Li 李耀先

Part Number: MSP430F5529

Hi Team,

Can this MCU use the code below to configure TIMER's ISR?

#pragma vector=TIMER1_A0_VECTOR

The reason why customer asked this question is because this error:

(Description Resource Path Location Type symbol "__TI_int59" redefined: first defined in "./main.obj"; ....)

Thanks & Regards,

You can use the format in our timer's examples like below to define the TIMER's ISR?

// Timer0 A0 interrupt service routine
#if defined(__TI_COMPILER_VERSION__) || defined(__IAR_SYSTEMS_ICC__)
#pragma vector=TIMER0_A0_VECTOR
__interrupt void TIMER0_A0_ISR(void)
#elif defined(__GNUC__)
void __attribute__ ((interrupt(TIMER0_A0_VECTOR))) TIMER0_A0_ISR (void)
#else
#error Compiler not supported!
#endif
{
P1OUT ^= 0x01; // Toggle P1.0
}

Hi Gary,

Thanks for your reply.

Yes, the customer is using this format, and reach the error above. Notice that he's using RTOS.

Thanks & Regards,

OK, which RTOS dose customer used? It seems the interrupt table is re-defined somewhere in the RTOS. It is better to provide the project here, that I can reproduce the issue on myside.

Hi Gary,

Thanks.

The customer use TI-RTOS(version: tirtos_msp43x_2_20_00_06). Here is the project: MSP430F5529_TIMER.zip

Thanks & Regards,

Hi Yale,

To create the interrupt ISR need to create Hwis in the TI-RTOS. More information you can refer to this document section 3.4 and there are examples how to create it.
