PIC18f26k80异步计数TMR1L和TMR1H总是在0

你好！我正在研究一个项目，我需要两个外部触发异步计数器。我目前正在试用PIC18F26K80这个应用程序，我遇到了一个问题，使用time1进行计数。TMR1L和TMR1H总是在0，我还没有弄清楚为什么它们不会计数。我现在用1kHz的5V 50%占空比方波来触发测试。我用MCC生成了代码，我自己看不出任何问题。定时器1初始化下面的代码：定时器0工作至今。这里是MCC生成的初始化代码：任何帮助都将不胜感激！如果你推荐任何其他的微控制器来运行两个异步计数器，我愿意接受建议！谢谢你，迪伦

    Hello!

I am working on a project in which I need two externally triggered asynchronous counters. I am currently experimenting with a PIC18f26k80 for this application and I am running into an issue with using Timer1 for counting. TMR1L and TMR1H are constantly at 0 and I have not been able to figure out why they will not count. I am triggering them right now with a 1KHz 5v 50% duty cycle square wave for testing.

I've generated the code with MCC and do not see any problems myself. Timer 1 Initialize code posted below:

void TMR1_Initialize(void)
{
    //Set the Timer to the options selected in the GUI

    //T1CKPS 1:1; RD16 enabled; SOSCEN disabled; nT1SYNC do_not_synchronize; TMR1CS T1OSC/T1CKI; TMR1ON off;
    T1CON = 0x86;

    //T1GSS T1G; TMR1GE disabled; T1GTM disabled; T1GPOL low; T1GGO done; T1GSPM disabled; T1GVAL disabled;
    T1GCON = 0x00;

    //TMR1H 0;
    TMR1H = 0x00;

    //TMR1L 0;
    TMR1L = 0x00;

    // Load the TMR value to reload variable
    timer1ReloadVal=(TMR1H << 8) | TMR1L;

    // Clearing IF flag.
    PIR1bits.TMR1IF = 0;

    // Start TMR1
    TMR1_StartTimer();
}


Timer 0 is working great so far. Here is the MCC generated initialization code for that:

void TMR0_Initialize(void)
{
    // Set TMR0 to the options selected in the User Interface

    // T0PS 1:256; T08BIT 16-bit; T0SE Increment_lo_hi; T0CS T0CKI; TMR0ON off; PSA not_assigned;
    T0CON = 0x2F;

    // TMR0H 0;
    TMR0H = 0x00;

    // TMR0L 0;
    TMR0L = 0x00;

    // Load TMR0 value to the 16-bit reload variable
    timer0ReloadVal = (TMR0H << 8) | TMR0L;


    // Clearing IF flag
    INTCONbits.TMR0IF = 0;

    // Start TMR0
    TMR0_StartTimer();
}

Any help would be greatly appreciated! If you would recommend any other microcontrollers for running two asynchronous counters, I am open to suggestions!

Thank You,
Dylan
