i'm working on LPC1114-FBD/301 series
On my board 4 LED's are connected to P0_8, P0_9, P0_10, P0_11.
I'v written a sample code toggle them. Only on 8 and 9 port pin LED's are blinking but on 10 and 11 there state is always on. here is the sample code
/* by default P0_8 and P0_9 pins are GPIO's */ LED_DIR |= BIT(8); LED_DIR |= BIT(9);
/* 9th and 10th pins are not GPIO's on reset */ // i think here some changes required to make them as GPIO's IOCON_SWCLK_PIO0_10 |= 0x1; IOCON_R_PIO0_11 |= 0x1;
LED_DIR |= BIT(10); LED_DIR |= BIT(11);
Thanks all.... Accessing IOCON register requires CLOCK to be enabled. I missed this instruction in my code
SYSAHBCLKCTRL |= 1<<16; /* Enables the clock for accessing IOCON register */
