为什么通过示波器在控制器PINS上看不到PWM

亲爱的，我已经产生PWM和闪光到控制器，但是我看不到输出上的各个引脚上的示波器。我已经产生了手写代码相同，我可以看到在示波器输出。当我比较了PTER的寄存器设置时，CLKDIV、PWMCON等不同于自动生成的代码。我的目标是从微芯片块中生成自动代码，并用它来查看示波器上的PWM。控制器使用的是DSPIC33 FJ32 202，FCY＝10MHz，PWM＝20kHz，PWM INT-PROGO-GT；4，死区时间1.16μs。端口引脚启用-RB12（PWMH）。我尝试启用OC和IC模块，但是我不确定模型中的设置，因此不能成功。我使用正弦查找表来生成PWM，正如鲁宾的一个论坛所建议的。谁能帮我解决这个问题？如果有人使用SIMULINK实现PWM，并在控制器上观察输出，请分享。谢谢。

    Dear All,

I have generated PWM and flashed to the controller, however I couldnt see the output on the respective pins on the oscilloscope. I have generated hand written code for the same and I could see outpt on oscilloscope. When I compared the register settings of PTER, CLKDIV,PWMCON etc differs from that of auto generated code. My aim is to generate auto code from the Microchip blocksets and flash it to view the PWM on oscilloscope. Controller used is dsPIC33fJ32202, Fcy = 10Mhz, PWM = 20Khz, PWM int prio-> 4, dead time - 1.16µs. Port pins enabled - RB12(PWMH).
I tried to enable OC and IC module but I am not sure about the settings in the model so couldnt succeed with it. I used sine Look up table to generate PWM as suggested by one of Lubin's forum. Could anybody help me to overcome the issue? kindly share if anybody have implemented the PWM using simulink and observed the output on controller.

Thanks in advance.
