CCS/EVM430-FR6047: Booster Pack GPIO

Part Number: EVM430-FR6047


Tool/software: Code Composer Studio

Hi,

I have an application that requires the GPIO pin of booster pack of EVM 430-FR6047 v1.0 to toggle.

I have chosen P7.5 and have adopted the following code(attached herewithin).

But unfortunately,the pin is not toggling instead its staying high.

Can i get some help?

#include <msp430.h>
#include <driverlib.h>
#include <stdint.h>


void SerialGPIOInit(void);

void main(void)
{
SerialGPIOInit();
}

void SerialGPIOInit(void)
{
    GPIO_toggleOutputOnPin(GPIO_PORT_P7,GPIO_PIN5);
}

Best Regards,

Divya Harikumar

    Hi Divya,

    You need set the pin as output mode firstly. Then call PMM_unlockLPM5() to activate port setting. Please seem below code.

    void main (void)
{
    //Stop WDT
    WDT_A_hold(WDT_A_BASE);

    //P7.5 output
    GPIO_setAsOutputPin(GPIO_PORT_P7,GPIO_PIN5);


    /*
     * Disable the GPIO power-on default high-impedance mode to activate
     * previously configured port settings
     */
    PMM_unlockLPM5();

    while(1)
    {
          //toggle pins
          GPIO_toggleOutputOnPin(GPIO_PORT_P7,GPIO_PIN5);

          __delay_cycles(1000000);
    }
}
