LAUNCHXL-CC26X2R1: Pins

Part Number: LAUNCHXL-CC26X2R1
Other Parts Discussed in Thread: SYSCONFIG

Hi TI,

 I want a Command to set output high for multiple pins.

Explaination of my case.

I have configured 5 LEDs. Using a constraint X.

If X=0 i want to 1 LED high

If X=20  , 2 LEDs high

If X=40 , 3 LEDs high

If X=60 , 4 LEDs high

If X=100 , 5 LEDs high

My requirement is command for setting multiple LEDs which are configured using GPIO pins high at a time.

    Hi,

    There is no command to set multiple GPIOs simultaneously. However, your use case can be addressed by calling 5 times the GPIO_write() function. 

    Make sure to use SysConfig to add the GPIOs you need. Then you can use code similar to the one below.

    GPIO_write(CONFIG_GPIO_LED_0, CONFIG_GPIO_LED_OFF);
GPIO_write(CONFIG_GPIO_LED_1, CONFIG_GPIO_LED_OFF);
GPIO_write(CONFIG_GPIO_LED_2, CONFIG_GPIO_LED_OFF);
GPIO_write(CONFIG_GPIO_LED_3, CONFIG_GPIO_LED_OFF);
GPIO_write(CONFIG_GPIO_LED_4, CONFIG_GPIO_LED_OFF);

switch (X)
{
  case 100:
      GPIO_write(CONFIG_GPIO_LED_4, CONFIG_GPIO_LED_ON);
  case 60:
      GPIO_write(CONFIG_GPIO_LED_3, CONFIG_GPIO_LED_ON);
  case 40:
      GPIO_write(CONFIG_GPIO_LED_2, CONFIG_GPIO_LED_ON);
  case 20:
      GPIO_write(CONFIG_GPIO_LED_1, CONFIG_GPIO_LED_ON);
  case 0:
      GPIO_write(CONFIG_GPIO_LED_0, CONFIG_GPIO_LED_ON);
}

    I hope this will help,

    Best regards,

    Hi Manikanth,

    The GPIO TI Driver will only set one GPIO per command, but you can use the Driverlib GPIO to write multiple GPIO with one command (i.e. GPIO_writeMultiDio).
