The best way for capturing low frequency signal

Hello,

I use STM32F103RBT6 @ 72Mhz to measure input frequency, but I need to measure frequencies between 500 to 3000Hz with PA1 pin - TIM2 CH2. What is the best way to do so?

I use code from STM32 examples - InputCapture that works, but measurable frequency is approx. 1000Hz+ which is not sufficient.

Can you tell me some better possiblities or possible modifications?

Thank you very much!
