Posted on May 17, 2011 at 15:09You need just to invert instruction order:     PD_DDR = 0x2D;                  \* PD7 input       *\     PD_CR1 = 0x2D;                   \* PD7 floating   *\     EXTI_CR1 = 0x48;                    EXTI_CR2 = 0x06;  ...

Posted on May 17, 2011 at 15:08You need just to reverse the instruction: 1. Set Pin sensitivity   EXTI_SetPinSensitivity(CIP_GPIO_PIN, EXTI_Trigger_Rising); 2. Configure PD7 as interrupt GPIO_Init(CIP_GPIO_PORT, CIP_GPIO_PIN, GPIO_Mode_In_PU_IT);   ...

Posted on May 17, 2011 at 15:07Timer 1 has a linear prescaler (any value from 1 to 65536), whilst the other timers have power of 2 prescaler (2^n with n=[0..15] for 16 bit timers), thus formulas are different...
