void k_gpio_init(int pin, KGPIOMode mode, KGPIOPullup pullup)¶

Initialize GPIO pin to specified mode.

I/O pin configuration described in MSP430x5xx Family Guide Section 12.2.4

Parameters

pin: number of pin to initialize
mode: pin mode to set
pullup: pin pullup value to set

unsigned int k_gpio_read(int pin)¶

Read in GPIO pin.

Return

unsigned int value read from pin

Parameters

pin: number of pin to read from

void k_gpio_write(int pin, unsigned int val)¶

Write to GPIO pin.

Parameters

pin: number of pin to write to
val: value to write

K_LED_0 P10¶: LED 0 pin.
