1.频率
/**根据需要的频率，求得单次高低电平的周期，再以50%占空比输出。**/
//设定开关频率 相当于 模拟输出一个pwm波，eg：100hz 50%
void led_frequency_ctrl(void)
{
period = 1/frequency*1000; //1
if(CheckDelay((uint32_t*)&time_f)==0)
{
Set_Delay_Time(period,(uint32_t*)&time_f); //1
}
if(time_f <= period/2) //2
{
PAout(1) = 1;
MP_ModBus1.Hold_Reg[2] = 0;
}
else
{
PAout(1) = 0;
MP_ModBus1.Hold_Reg[2] = 1;
}
}
/**之后再1ms调用**/
static void Task_1ms(void)
{
DelayTimeCount_ms((uint32_t*)&time_f); //!!!
TimeCountReceive(&U_D_Uart2);
}
2.modbus主从机主要代码
注：主机只需要发什么功率什么频率以及读取已经处理好的监控值，真正控制处理灯的是从机。
例如：
第三功能，需要只在开灯情况下读取监控值，那么就让从机只在开灯状态才存入就好，这样主机获取的都是开灯状态下的值，不需要自己在判断。
再例如：
设定频率，主机只需要告诉从机，你要以多大频率开关灯，从机得知后自主转换控制频率。而不是之前，主机亲自控制每一次开关达到控制频率效果，复杂而且通信量很大出错率也高。
/**主机**/
/**实现3/4个功能：1.灯开关频率设定 2.功率设定 3.读取监控值**/
