recently himself wrote a small program, stm32 main function is to use the timer capture capabilities to another timer to count the number of pulses produced by PWM, and the pulse with the third timer configuration fixed time calculated, the results of the final output via a serial port, but in the program to the board can't show the number of pulses, through a simulation found that run inside the program has been in the timing of the output, the output has been to 0, here to ask you a great god, and the co., specific how to configure in order to ensure the correct results output?

Can you share code (though very long)
