如何使用pic24f中的32位定时器

嗨，我正在尝试使用32位定时器（2-3）在PIC24FJ128GA310，与FoSC＝8兆赫。下面是我的代码，它没有给我10秒延迟”void timer32_Init(){T2CON=0x00；//停止任何16/32位Timer2操作T3CON=0x00；//停止任何16位Timer3操作TMR3=0x00；//清除timer3寄存器TMR2=0x00的内容；//清除timer2寄存器PR3=0xFFFF；//L将值0xFF PR2=0xFFFF;//用值0xFF IPC2bits.T3IP=0x01加载周期寄存器2；//设置Timer3中断以获得期望的优先级级别//（此示例指定级别1优先级）IFS0bits.T3IF=0；//清除Timer3中断状态标志IEC0bits.T3I。E＝0；//启用Time3中断T2CONTITES。T32＝1；//启用32位定时器操作T2CONBITS。吨＝1；/ /启动带预分频器T2CONC＝0x8038的32位定时器；//设置为1:1，时钟源设置为/ /内部指令周期}“”定义延迟-10秒156250 / /十秒延迟空间主（空）{INTCTalp；CARR Re=＝'''′0′；int TimeLLSB＝0，TimeMsMs=＝0；未签名的long TimeTMR32（）；UART2INITE（）；Time1GIN（）；TrcRe2初始化（）；PutsNuTART1（Buff，SaMPTF（Buff，“欢迎rn”））；Delay1（），PuffsNuTAR1（Buff，Simulf（Buff）”ONT，x＝0，y＝4，z＝3，i；无符号字符rn")))TMR3HLD=0;TMR3HLD=0;TMR3HLD=0；//重新启动计数TMR2=0；//重新启动计数TMR2=计数TMR2=0；//重新启动计数//TMR2/TMR2计数/TMR3HLD=0；//重新启动计数//TMRTMR3HLD计数//TMRTMR3HLD=0/TMR3HLD=2；///00X0000000002; //重新启动计数//重新启动计数//TMWHSW//TMWW//TMR2//TMR2//TMR2//TMR2//TMR2//TMR2//TMR2//TMR2_l***=TMR2;//Transfer t他将LSW转换为temp_l*** temp_m***=TMR3HLD；//将MSW从保持寄存器传输到temp_TMR32=temp_m****65536+temp_l***;}putsNUART1(buff,sprintf(buff,“hirn”)}“请帮助”。

    hi , I am trying to use 32 bit timer (2-3) in pic24fj128ga310, with Fosc = 8 MHz. Below is my code which is not giving me 10 sec delay
"
void Timer32_Init(){
T2CON = 0x00; //Stops any 16/32-bit Timer2 operation
T3CON = 0x00; //Stops any 16-bit Timer3 operation
TMR3 = 0x00; //Clear contents of the timer3 register
TMR2 = 0x00; //Clear contents of the timer2 register
PR3 = 0xFFFF; //Load the Period register3 with the value 0xFFFF
PR2 = 0xFFFF; //Load the Period register2 with the value 0xFFFF
IPC2bits.T3IP = 0x01; //Setup Timer3 interrupt for desired priority level
//(this example assigns level 1 priority)
IFS0bits.T3IF = 0; //Clear the Timer3 interrupt status flag
IEC0bits.T3IE = 0; //Enable Timer3 interrupts
T2CONbits.T32 = 1; //Enable 32-bit Timer operation
T2CONbits.TON = 1; //Start 32-bit timer with prescaler
T2CON = 0x8038;
//settings at 1:1 and clock source set to
//the internal instruction cycle
}

#define delay_10sec 156250  // ten sec delay
void main(void)
{
int count,x=0,y=4,z=3,i;
unsigned char temp;
char arr2[] = {''};
char rec = '';
int temp_l***=0,temp_m***=0;
unsigned long temp_TMR32=0;

putsNUART1(buff,sprintf(buff,"WELCOMErn"));

putsNUART1(buff,sprintf(buff,"WELCOMErn"));

TMR3HLD = 0; // restart the count
TMR2 = 0; // restart the count
// TMR3HLD = 2; //0x0002; // HSW
// TMR2 = 25178; //0x625A; //
PR3 = 0x0002; //Load the Period register with the value 'delay' for 10 sec
PR2 = 0x625A;
while ( temp_TMR32 < delay_10sec){
temp_l*** = TMR2; //Transfer the LSW into temp_l***
temp_m*** = TMR3HLD; //Transfer the MSW from the holding register to into
temp_TMR32 = temp_m*** * 65536 + temp_l***;
}
putsNUART1(buff,sprintf(buff,"hirn"));
