Hi guyz simple question..

Im trying to get my way in stm32 platform and I am playing around with the samples. I have this

typedef enum

{

  LEd3 = 1,

  LED4 = 0,

  c0=1,

  c1=3,

  c2=4,

  c3=5,

  c4=6,

  c5=7,

  c6=8,

  c7=9

} Led_TypeDef;

#define LEDn                             10

#define LED4_PIN                         GPIO_Pin_8  

#define LED4_GPIO_PORT                   GPIOC

#define LED4_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define LED3_PIN                         GPIO_Pin_9  

#define LED3_GPIO_PORT                   GPIOC

#define LED3_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define c0_PIN                         GPIO_Pin_0  

#define c0_GPIO_PORT                   GPIOC

#define c0_GPIO_CLK                    RCC_APB2Periph_GPIOC

#define c1_PIN                         GPIO_Pin_1  

#define c1_GPIO_PORT                   GPIOC

#define c1_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define c2_PIN                         GPIO_Pin_2  

#define c2_GPIO_PORT                   GPIOC

#define c2_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define c3_PIN                         GPIO_Pin_3  

#define c3_GPIO_PORT                   GPIOC

#define c3_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define c4_PIN                         GPIO_Pin_4  

#define c4_GPIO_PORT                   GPIOC

#define c4_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define c5_PIN                         GPIO_Pin_5  

#define c5_GPIO_PORT                   GPIOC

#define c5_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define c6_PIN                         GPIO_Pin_6  

#define c6_GPIO_PORT                   GPIOC

#define c6_GPIO_CLK                    RCC_APB2Periph_GPIOC  

#define c7_PIN                         GPIO_Pin_7  

#define c7_GPIO_PORT                   GPIOC

#define c7_GPIO_CLK                    RCC_APB2Periph_GPIOC 

void STM32vldiscovery_LEDInit(Led_TypeDef Led);

void STM32vldiscovery_LEDOn(Led_TypeDef Led);

void STM32vldiscovery_LEDOff(Led_TypeDef Led);

void STM32vldiscovery_LEDToggle(Led_TypeDef Led);

void STM32vldiscovery_PBInit(Button_TypeDef Button, ButtonMode_TypeDef Button_Mode);

uint32_t STM32vldiscovery_PBGetState(Button_TypeDef Button);

and in my main i have this

    /* Turn on LD2 and LD3 */

    STM32vldiscovery_LEDOn(LEd3);

    STM32vldiscovery_LEDOn(LED4);    

   /* Insert delay */

    Delay(0xAFFFF);

    /* Turn off LD3 and LD4 */

    STM32vldiscovery_LEDOff(LEd3);

    STM32vldiscovery_LEDOff(LED4);

    /* Insert delay */

    Delay(0xAFFFF);

    

    STM32vldiscovery_LEDOn(c0);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c0);

    STM32vldiscovery_LEDOn(c1);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c1);

    STM32vldiscovery_LEDOn(c2);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c2);

    STM32vldiscovery_LEDOn(c3);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c3);

    STM32vldiscovery_LEDOn(c4);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c4);

    STM32vldiscovery_LEDOn(c5);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c5);

    STM32vldiscovery_LEDOn(c6);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c6);

    STM32vldiscovery_LEDOn(c7);

    Delay(0xAFFFF);

    STM32vldiscovery_LEDOff(c7);

it would stop on led 3 and led 4 my suspicion is i did something wrong in the enum....

Ah I understood it now.. thanks to clive previous guidance... the enum was for the array

GPIO_TypeDef* GPIO_PORT[LEDn] = {LED3_GPIO_PORT, LED4_GPIO_PORT, c0_GPIO_PORT, c1_GPIO_PORT, c2_GPIO_PORT, c3_GPIO_PORT, c4_GPIO_PORT, c5_GPIO_PORT, c6_GPIO_PORT, c7_GPIO_PORT};

from STM32vldiscovery.c ... I'm starting to get hand of this new platform...
