[ARM-PowerPC-ColdFire-MIPS] ruanjiandingshiqi DL : 0: 本软定时器模快所通过一个唯一的索引（即序号）来表识每一个软定时器，这个序号从0到MAX_SOFT_TIMER-1 ，最多为255个。要使用软定时器模块，首先需要让软定时器管理任务运行起来。软定时器管理任务的函数名称为SoftTimer，所以只需要Small RTOS的要求在Config.h的数组TaskFuction加上SoftTimer项即可。因为软定时器执行的任务时间等因素不确定，所以一般把这个任务优先级定得比较低。-the soft-timer module adopted by only one index (ie serial numbers) to form a soft know each timer, the serial number from 0 to MAX_SOFT_TIMER-1, a maximum of 255. To use soft timer module, the first need for the soft-timer management tasks running up. Soft-timer management tasks for the function name SoftTimer. So Small RTOS only at the request of an array TaskFuction Config.h SoftTimer items can be added. Soft-timer because the task uncertain factors such as time, in general the priority tasks set aside a lower level.

[ARM-PowerPC-ColdFire-MIPS] CAPTURE DL : 0: PIC单片机的CCP功能 //220V的交流电源直接用电阻限流,经光耦隔离,形成脉冲送到CCP2, //CCP2模块的捕捉功能,设置为每16个上升沿捕捉一次,相当于平均滤波,目的是为了减小误差 //TMR1计数的分频系数计算:假设电源为50Hz,即一个周期为20ms,16个周期为320ms //320ms=320000us,单片机用4MHz晶振,指令周期为1us,设TMR1的分频系数为K:65536×K=320000 //得K=4.88,取K=8,即TMR1的预分频系数设为1:8 //电源频率计算,假设频率显示为2位小数,即频率值放大100倍,16次捕捉值为TTZ, //则f=1000000×100/(TTZ×8/16)=200000000/TTZ-PIC microcontroller CCP function// 220V AC power directly limiting resistor, the optocoupler isolation, a pulse sent CCP2,// CCP2 module' s capture function, set to capture rising once every 16, equivalent to an average filter The purpose is to reduce the error// TMR1 counter division ratio calculation: Suppose power is 50Hz, ie a period of 20ms, 16 cycles of 320ms// 320ms = 320000us, microcontroller 4MHz crystal, the instruction cycle is 1us, setting TMR1 divider coefficient K: 65536K = 320000// get K = 4.88, take K = 8, ie the TMR1 prescaler is set to 1:8// power frequency, assuming that the frequency is displayed as two decimal that frequency value magnified 100 times, 16 times to capture value TTZ,// then f = 1000000100/(TTZ8/16) = 200000000/TTZ
