I want to measure the time between two pulses, from a Hall sensor. and send it via Rs232 to the PC. To be used For measuring of an engine speed. Code: word PM_Value; void Timer1_ISR(void) { int irqcnt; PM_Value=Timer_T1GetPM(); irqcnt=Irq_GetCount(INT_TIM1CAPT); } void main(void) { byte n; Serial_Init(0,SR_8BIT|SR_1STOP|SR_NO_PAR,SR_BD9600); Irq_SetVect(INT_TIM1CAPT,Timer1_ISR); Timer_T0PWM(100,PS0_64); // Start Pulse Generator Timer 0 // Measurement starts here // Output Timer0 OC0(PortB.3) connect to ICP(input capture pin, PortD.6) PM_Value=0; // Set mode to Pulse Width Measurement and determine prescaler Timer_T1PM(0,PS_64); while(PM_Value==0); // Measure Pulse Width or Period Serial_Write(0,PM_Value); // Output Measuring Value } Is an there incorrect in this code?
