Macro issue KSDK1.2.0 (FRDM-KL25Z)

nelsonlobo — Fri, 04 Sep 2015 13:45:38 GMT

Hi,

Ive looked up several sample codes and have finally decided to write a code myself. Also looked up KL25 family reference manual for the same purpose to understand the arrangement/assignment of registers.

The code is located in I:/folder1/folder2/folder3/folder4/folder5/1.GPIO_Setup location while the KDS1.2.0 installation is located at C:/Freescale/ location.

For which i have also provided include locations for necessary files being refernced in Tool Settings for Cross ARM C Compiler.

The code is basically toggling LEDs i.e. the RGB available on pins 18,19 on portB and pin 1 on portD, which would be as follows:

#include "MKL25Z4.h"

#include "fsl_device_registers.h"

#include "fsl_clock_manager.h"

#include "fsl_smc_hal.h"

#include "fsl_port_hal.h"

#include "fsl_sim_hal.h"

#include "fsl_gpio_driver.h"

/*as mentioned in fsl_gpio_driver.h inorder to gain access of GPIOs*/

enum _gpio_pins

{

kGpioLED1 = GPIO_MAKE_PIN(GPIOB_IDX, 19), /* FRDM-KL25Z4 Green LED */

kGpioLED2 = GPIO_MAKE_PIN(GPIOB_IDX, 18), /* FRDM-KL25Z4 Red LED */

kGpioLED3 = GPIO_MAKE_PIN(GPIOD_IDX, 1), /* FRDM-KL25Z4 Blue LED */

kGpioSW1 = GPIO_MAKE_PIN(GPIOD_IDX, 6), /* FRDM-KL25Z4 power manager */

};

/*initialize GPIOs variables array*/

extern gpio_input_pin_user_config_t switchPins[];

extern gpio_output_pin_user_config_t ledPins[];

/* Declare Output GPIO pins */

gpio_output_pin_user_config_t ledPins[] = {

{

.pinName = kGpioLED1,

.config.outputLogic = 1,

.config.slewRate = kPortSlowSlewRate,

.config.driveStrength = kPortLowDriveStrength,

{

.pinName = kGpioLED2,

.config.outputLogic = 1,

.config.slewRate = kPortSlowSlewRate,

.config.driveStrength = kPortLowDriveStrength,

{

.pinName = kGpioLED3,

.config.outputLogic = 1,

.config.slewRate = kPortSlowSlewRate,

.config.driveStrength = kPortLowDriveStrength,

{

.pinName = GPIO_PINS_OUT_OF_RANGE,

}

};

/*Use following Macros to access the PORT pins*/

#define LED3_DIS (PORT_HAL_SetMuxMode(PORTD, 1, kPortMuxAsGpio)) /*!< Enable target LED3 */

#define LED1_OFF (GPIO_DRV_WritePinOutput(ledPins[0].pinName, 1)) /*!< Turn off target LED1 */

#define LED2_ON (GPIO_DRV_WritePinOutput(ledPins[1].pinName, 0)) /*!< Turn on target LED2 */

#define LED3_ON (GPIO_DRV_WritePinOutput(ledPins[2].pinName, 0)) /*!< Turn on target LED3 */

#define LED1_TOGGLE (GPIO_DRV_TogglePinOutput(ledPins[0].pinName)) /*!< Toggle on target LED1 */

#define LED2_TOGGLE (GPIO_DRV_TogglePinOutput(ledPins[1].pinName)) /*!< Toggle on target LED2 */
