LPC11U14 board routines . . .

First search, looking for how NXP demo toggles a given GPIO:

user:~/Downloads/nxp/lpcopen$ grep -nr Board_LED_Toggle ./*

./nxp_lpcxpresso_11u14_board_lib/src/board.c:137:void Board_LED_Toggle(uint8_t LEDNumber)
./nxp_lpcxpresso_11u14_board_lib/inc/board_api.h:112:void Board_LED_Toggle(uint8_t LEDNumber);
./nxp_lpcxpresso_11u14_periph_clkout/example/src/clkout.c:77:		Board_LED_Toggle(0);
./nxp_lpcxpresso_11u14_periph_pinint/example/src/pinint.c:187:		Board_LED_Toggle(0);
./nxp_lpcxpresso_11u14_periph_uart/example/src/uart.c:135:				Board_LED_Toggle(0);/* Toggle LED if the TX FIFO is full */
./nxp_lpcxpresso_11u14_periph_watchdog/example/src/watchdog.c:65:		Board_LED_Toggle(0);
./nxp_lpcxpresso_11u14_periph_watchdog/example/src/watchdog.c:72:	Board_LED_Toggle(0);

The routine itself in file ~/Downloads/nxp/lpcopen/nxp_lpcxpresso_11u14_board_lib/src/board.c:

    137 void Board_LED_Toggle(uint8_t LEDNumber)
    138 {^M
    139         if (LEDNumber == 0)^M
    140                 Chip_GPIO_SetPinToggle(LPC_GPIO, 0, 7);
    141 }

Next search:

$ grep -nr Chip_GPIO_SetPinToggle ./*

user:~/Downloads/nxp/lpcopen$ grep -nr Chip_GPIO_SetPinToggle ./*
./lpc_chip_11uxx_lib/inc/gpio_11xx_1.h:447:STATIC INLINE void Chip_GPIO_SetPinToggle(LPC_GPIO_T *pGPIO, uint8_t port, uint8_t pin)
Binary file ./nxp_lpcxpresso_11u14_board_lib/src/.board.c.swp matches
./nxp_lpcxpresso_11u14_board_lib/src/board.c:140:		Chip_GPIO_SetPinToggle(LPC_GPIO, 0, 7);
