LAUNCHXL-CC1352P: Is the number of buttons limited?

Edward Shyshonkov

Hi,

I am using some code form no-Rtos LEDs and buttons example.

Custom board in Configsys.

I am trying to read 6 buttons. 5 buttons work well. When I add the 6th one, it does not work. Callback on the 6th is ignored.

I have increased number of buttons in #define to 6 or 7 - no luck.

If I comment out oppening of any one of 6 buttons all the other 5 work well, including my number 6 .

Is there some limit for the number of buttons in the Button library? If yes, how can I change it?

I did appreciated the simple access this library provides to clicks, double clicks etc.

Thanks,

Regards ,

Edward.

Hi,

There is not limit to number buttons you can hook up.

Which particular example are you using from the SDK?

Thanks,

Hi,

I am going to go ahead and close this issue. If you are still having a problem, feel free to re-open, or if the thread is locked create a new one.

Thanks,

Riz

Hi Riz,

Thanks for the answer, I missed the previous one.

What I did was just reduced the number of buttons in my project. The question "Why I am not able to add the 6th button" remains open. The example I am using is no-RTOS rfPacketTx with #include <ti/drivers/apps/Button.h>.

I have attached the project.

When I add the 6th button it works, but one of the original 5 stops working.

Regards,

Edward.

Hi,

I tested interrupts on 6 IOs without issues. All interrupts were firing. I used low level driverLib APIs to build the code.

You can use the following setup code to test. Note: this is only setup for one GPIO, add more IOs in similar fashion

#define EXAMPLE_IOID_EDGE1         IOID_14
..
...
// Power up the periph domain and wait for it to become available. 
    //
    PRCMPowerDomainOn(PRCM_DOMAIN_PERIPH);
    while(PRCMPowerDomainStatus(PRCM_DOMAIN_PERIPH) != PRCM_DOMAIN_POWER_ON); 
    
    //
    // Enable GPIO module and wait for it to be ready
    //
    PRCMPeripheralRunEnable(PRCM_PERIPH_GPIO);
    PRCMLoadSet();
    while(!PRCMLoadGet())
    { }
  
  
    //
    // Set GPIO as input.
    // Pin is configured with internal pull-up, edge detect on falling edge
    // and interrupt enable on edge detection.
    //

    IOCPinTypeGpioInput(EXAMPLE_IOID_EDGE1);
    IOCIOPortPullSet(EXAMPLE_IOID_EDGE1, IOC_IOPULL_UP);
    IOCIOIntSet(EXAMPLE_IOID_EDGE1, IOC_INT_ENABLE, IOC_FALLING_EDGE);
    IOCIntEnable(EXAMPLE_IOID_EDGE1);

   
    // 
   GPIODirModeSet(EXAMPLE_GPIO_BTN, GPIO_DIR_MODE_IN);

    //
    // Enable the interrupt for edge detect
    //
    IntEnable(INT_AON_GPIO_EDGE);
    
    //
    // Enable processor interrupts
    //
    IntMasterEnable();

// Interrupt handler is below:

void
GPIOIntHandler(void)
{
    //
    // Clear the interrupt
    //
       IOCIntClear(EXAMPLE_IOID_EDGE1);
     //
    // Set an interrupt flag to indicate an interrupt has occurred.
    //
    g_bGPIOIntFlag = true;
}

Hi FI,

Thank you. It works this way.
