CCS: MSP432P401M starting help

Hello George,

I recommend looking at the code examples from the link below.  You can also find the simplelink academy in the same link to help get started if you are new to this platform.

Helo and thank you for your reply,

I made the 1st)reading inputs.

I am wondering what example should I look to create in my system an internal timer in seconds.

Thanks

George,

You could look at the example below which sets up a 1 sec timer and blinks an LED.

Hello thank you for your reply,

I have one problem. I want to count the input interruptions only.

I use that code.

GPIO_setConfig(CONFIG_GPIO_DIGI_INPUT1, GPIO_CFG_IN_PU | GPIO_CFG_IN_NOPULL);
GPIO_setCallback(CONFIG_GPIO_DIGI_INPUT1, countFirstInput);
GPIO_enableInt(CONFIG_GPIO_DIGI_INPUT1);

my countFirstInput function is:

void countFirstInput(uint_least8_t index)
{
DigiCounter[0]++;
printf("%d\n",DigiCounter[0]);
fflush(stdout);
}

But I want use that function only when the cable interupts.

Now when I connect the cable it runs one time and prints in my screen =1 and when I disconnect the cable(interrupt) it runs two times and prints in my screen 2 and 3. Can you explain to me what is wrong?

Thank you!

You can't call printf() in an interrupt handler.

printf returns values to screen so I can call it.
