Hello everyone,
Below you can see the pattern of how the micro and connected MK10DN512ZVLL10 tab made by my university ...
Enabling the button highlighted in yellow?
How instruction can read their status?
Thanks in advance for any indicaizone
Hello Niki,
Are you using KSDK or any RTOS?
If you are in baremetal it is very simple. Please see the answer in the post below to see how to manage the GPIO pins.
Best regards,
Earl.

Here is how to configure and read your input in the uTasker project:
#define BUTTON_SOS (PORTC_BIT16)
_CONFIG_PORT_INPUT_FAST_HIGH(C, BUTTON_SOS, PORT_PS_UP_ENABLE);
if (_READ_PORT_MASK(C, BUTTON_SOS) != 0) {
fndDebugMsg("SOS is not pressed\n\r");
}
else {
fndDebugMsg("SOS is pressed\n\r");
}
If you prefer to configure an interrupt to fire when the button is pressed, the following code does it:
INTERRUPT_SETUP interrupt_setup; // interrupt configuration parameters
interrupt_setup.int_type = PORT_INTERRUPT; // identifier to configure port interrupt
interrupt_setup.int_handler = fnButtonPressed; // handling function
interrupt_setup.int_priority = 5; // interrupt priority level
interrupt_setup.int_port = PORTC; // the port that the interrupt input is on
interrupt_setup.int_port_bits = BUTTON_SOS;
interrupt_setup.int_port_sense = (IRQ_FALLING_EDGE | PULLUP_ON); // interrupt is to be falling edge sensitive
fnConfigureInterrupt((void *)&interrupt_setup); // configure interrupt
whereby the interrupt callback to handle the press is something like:
// Button interrupt handler
//
static void fnButtonPressed(void)
{
fnInterruptMessage(BUTTON_TASK, E_BUTTON_PRESSED);
}
Why not add your board to the uTasker project so that you can simulate and test all operation and greaty accelerate your work with it?
Take a look at the following University board that was added to it in just a couple of hours (including SD card and USB operation):
µTasker Kinetis Capuccino-KL27 support
