怎么在示波器中编程和显示PWM占空比PIC16F87A

大家早上好，我是这个小组的新手，我需要你们的帮助，我必须在示波器中编程和显示PWM占空比PIC16F87A，所以我用Mikro C编程和MPLAB IDX，我想让我的占空比自动改变，所以我编写了这个程序空主（）{ int dutyCurry.PWM1IIIT（5000）；/*初始化PWM模块和循环时间（TUN+TOFF）被设置为100×/pWM1x开始（）；/*开始PWM信号生成在选定的针* /（1）{ for（dutyClult= 25；DutyClult＆lt；255；DutyClult= DutyClult+25）{PWM1SeTyLoad（DutyCurror）；DelayyMs（100）；} } } } } } } } } } }我的问题是我不能拥有一个占空比信号变化缓慢，当延迟增加到1000毫秒时，例如我失去信号，提前感谢你。

    Good morning everybody,

I'm new in this group, I need your help, i have to program and display a PWM duty cycle pic16f887A in an oscilloscope so i have used miKro C for programming and MPLAB IDE X , i want to have my duty cycle changing automatically so i wrote this program
void main()
{
int dutyCycle;
PWM1_Init(5000); /* Initialize the PWM module and the Cycle time(Ton+Toff) is set to 100*/
PWM1_Start(); /* Start PWM signal generation on Selected pin */
while(1)
{
for(dutyCycle=25;dutyCycle<255;dutyCycle=dutyCycle+25)
{
PWM1_Set_Duty(dutyCycle);
DELAY_ms(100);
}
}
}
my problem is that i can't have a duty cycle signal changing slowly , when increasing the delay to 1000 ms for example i lose my signal

thank you in advance
