Hello , I have tried to modify the led_blinky demo code to blink the GREEN LED for a month.
But even I modified all the functions about LED in the main function, It still doesn't work.
The demo code version is SDK_2_9_0_LPCXpresso824MAX-lpcxpresso824max_led_blinky
Those functions that I have been modified are
======================================
pin_mux.c - BOARD_InitPins
add
const uint32_t IOCON_INDEX_PIO0_16_config = (/* Selects pull-up function */
IOCON_PIO_MODE_PULLUP |
/* Enable hysteresis */
IOCON_PIO_HYS_EN |
/* Input not invert */
IOCON_PIO_INV_DI |
/* Disables Open-drain function */
IOCON_PIO_OD_DI |
/* Bypass input filter */
IOCON_PIO_SMODE_BYPASS |
/* IOCONCLKDIV0 */
IOCON_PIO_CLKDIV0);
IOCON_PinMuxSet(IOCON, IOCON_INDEX_PIO0_16, IOCON_INDEX_PIO0_16_config);
======================================
pin_mux.h
add
#define BOARD_LED_GREEN_PERIPHERAL GPIO /*!<@brief Device name: GPIO */
#define BOARD_LED_GREEN_SIGNAL PIO0 /*!<@brief GPIO signal: PIO0 */
#define BOARD_LED_GREEN_GPIO GPIO /*!<@brief GPIO device name: GPIO */
#define BOARD_LED_GREEN_GPIO_PIN 16U /*!<@brief PIO0 pin index: 12 */

#define BOARD_LED_GREEN_DIRECTION kPIN_MUX_DirectionOutput /*!<@brief Direction */

Could anyone tell me where did I make mistakes?
Thanks a lot
