应该在每个通道设置一个定时器溢出次数累加变量，每个变量在中断中计算出方波的时间后清零。如： #pragma CODE_SEG NON_BANKED
void interrupt 10 ISR1(void)
{
C1CapTimeNew =TC2;
C1IntTimeNew=65536*C1TovCount + C1CapTimeNew - C1CapTimeOld ;
C1TovCount=0;
C1CapTimeOld=C1CapTimeNew;
}
void interrupt 9 ISR2(void)
{
C2CapTimeNew=TC1;
C2IntTimeNew = 65536*C2TovCount + C2CapTimeNew - C2CapTimeOld ;
C2TovCount=0;
C2CapTimeOld=C2CapTimeNew;
}
void interrupt 16 Timer_Overflow_ISR(void)
{
C1TovCount++;
C2TovCount++;
(void)TCNT;
}
#pragma CODE_SEG DEFAULT
