Posted on October 20, 2015 at 11:29gpioc pin 0 and gpio a pin 0 &1 work fine
but gpio c pin 1 and furhter show 0.5v at output instead of 3 volts.
here is the code i implemented
&sharpinclude ''main.h''
static __IO uint32_t TimingDelay;

GPIO_InitDef.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitDef.GPIO_OType = GPIO_OType_PP;
GPIO_InitDef.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_InitDef.GPIO_Speed = GPIO_Speed_50MHz;
//Initialize pins
GPIO_Init(GPIOC, &GPIO_InitDef);

//Initialize pins

//volatile int i;}
