Hi Folks,

 

LEDs do not work with the examples source code shared by NXP, lpcopen_2_18_lpcxpresso_nxp_lpcxpresso_1837

 

on board we have 3 LEDs

Red - Power indicator

Yellow & Blue  - (user configurable), these are connected to GPIO1[11] & GPIO1[12], do the following modifications in the lpc_board_nxp_lpcxpresso_1837/src/board.c file

 

//remove this line

-static const io_port_t gpioLEDBits[] = {{3, 5}, {0, 7}, {3, 7}};

//add this line

+static const io_port_t gpioLEDBits[] = {{3, 5}, {1, 11}, {1, 12}};

 

use the MACROS LEDS_LED1 & LEDS_LED2 to make then turn ON/OFF using the api Board_LED_Set(LEDS_LED2, 1);

 

Thanks & Regards,

Vamshi G.
