example6_TIM
本例展示了如何设置TIM,用它来测量一个外部输入信号的频率和占空比。
TIM2时钟设置为72MHz,预分频设置为0,TIM2计数器时钟可表达为:
TIM2 counter clock = TIMxCLK / (Prescaler +1) = 72 MHz,因此可测量的最小频率值为1100Hz。
设置TIM2工作在PWM输入模式(PWM Input Mode),把外部信号作为输入连接到TIM2通道2。
利用TIM2计数器中断来测量信号的频率和占空比。在TIM2_IRQHandler中,计算信号的频率和占空比,方法如下:
变量"Frequency"为由下式得到的外部信号频率:
Frequency = TIM2 counter clock / TIM2_CCR2 单位Hz
变量"Duty_Cycle"为由下式得到的外部信号占空比:
Duty_Cycle = (TIM2_CCR1*100)/(TIM2_CCR2) 单位
(This example shows how to set up the TIM, and use it to measure the frequency and duty cycle of an external input signal. TIM2 clock set to 72MHz and the prescaler is set to 0, TIM2 is counter clock can be expressed as: TIM2 is counter clock = TIMxCLK/(prescaler. Ppls1) = 72 MHz, the minimum measurable frequency value of 1100 Hz. Set TIM2 PWM input mode (PWM Input Mode), the external signal as an input connected to the the TIM2 Channel 2. TIM2 counter interrupt signal to measure frequency and duty cycle. Calculate the frequency and duty cycle of the signal in TIM2_IRQHandler as follows: variable " Frequency" on the grounds of the external signal frequency by the following formula: Frequency = TIM2 is counter clock/TIM2_CCR2 unit Hz variable Duty_Cycle " on the grounds of the following formula to get external duty cycle: Duty_Cycle = (TIM2_CCR1* 100)/(TIM2_CCR2) in )

vc-csv
Vc++读写csv文件的类,这个资源是读写CSV文件的非常实用的类。方法写得非常好,代码也写得非常简洁,很合适在实际项目中使用。经本人测试,只要把上面的代码CSVOperator.h、CSVOperator.cpp和StringParser.h拷贝到项目中,就可以直接使用。在CSV_OP.cpp文件中,main方法里面有详细的读取文件的方法。读取的是config.csv这个文件。(Class Vc++ read and write csv file, this resource is to read and write CSV file very useful class. The method is very good, the code is written in a very simple, very suitable for use in the actual project. I tested, above code CSVOperator.h the, CSVOperator.cpp and StringParser.h copy to the project, can be used directly. In the CSV_OP.cpp file, the main method inside the detailed method of reading the file. Read this file config.csv.)
