we tried method you have suggested but getting 1.1876 us time with nop operation. without nop operations it was 560ns

in our project 16MHz is system clock so if 1 instruction per clock cycle then 1/16MHz = 0.000000625 i.e 625ns. we are calculating time duration by using following code. as per above calculation 0.000000625 * 240 = 150us but we are getting 74us on sco...

Thanks for reply. No We are using HSE as clock source

How to calculate instruction execution time in stm32f103. In data sheet they have given --72 MHz maximum frequency, 1.25 DMIPS/MHz (Dhrystone 2.1) performance at 0 wait state memory access. please help me on this

I am using stm32f103 for project and keil ide for the compilation. I have configured timer 2 having 16 MHz clk frequency. I need to generate interrupt at 100 ms so I have configured Prescaler val as 24 and period val as 63999. but getting at 95 or 112 ms
