利用P2.0输出的时钟信号ACLK来模拟外部的脉冲电平,利用捕获/比较器1来
进行脉冲宽度测量,这里利用的是子系统SMCLK时钟来作为计数的。
测量脉冲宽度计算公式:[overflow*65535+(end-start)]*SMclk(周期)
MCLK:8MHz SCLK:1MHz ACLK:32768Hz/8
待测信号:1/[32768/8(分频)]*(1/2)=高电平时间
参考信号测量:(end-start)]*SMclk(1/1M)=122/10^6
描述:将P2.0引脚与P1.2引脚相连(The output clock signal ACLK is used to simulate the external pulse level, using the capture / comparator 1 to P2.0
Pulse width measurement, where the subsystem SMCLK clock is used as a count.
The formula of measuring pulse width is [overflow*65535+ (end-start)]*SMclk (cycle)
MCLK:8MHz SCLK:1MHz ACLK:32768Hz/8
The sensing signal (frequency: 1/[32768/8)]* (1/2) = high level time
Reference signal measurement: (end-start)]*SMclk (1/1M) =122/10^6
Descr iption: connect the P2.0 pin to the P1.2 pin)
