I am using stm32f103rbt6 for frequency capturing. I am trying to use timer1 channel1 and channel2 to capture two different frequency say 1K and 500 hertz. Once 1k frequency rising edge is detected i am reading the CCMR1 value and clearing the CNT register for next rising edge so 500 hertz frequency is not detecting properly because only one counter register is available pls let me known how to over come this problem. Thank u all in advance.....
