    How to use Filter Polling method for channel A and channel B?

    user_504416177

      Hello Every One,

         

      I am trying to implement polling method for channel A and channel B of my filter.

         

      I am following and example project. This project is written for Channel A only. I have some confusion in it. I wrote the following code for channel A and B. Kindly tell me if am i am doing it write:

         

      I am doing the following:

         

      ADC---->Filter---->DAC.

         

      Code:

         


      #include <device.h>
      #include <VDAC8.h>
      #include <math.h>
      #include <stdio.h>
          
      void DMA_ADC_ChA_Config(void);

         

      void DMA_ADC_ChB_Config(void);

         

      int main()
      {

         

       ADC_ChA_Start();
          ADC_ChA_IRQ_Start();
          ADC_ChA_StartConvert();
          ADC_ChB_Start();
          ADC_ChB_IRQ_Start();
          ADC_ChB_StartConvert();
          VDAC_ChA_Start();
          VDAC_ChB_Start();
          Filter_Start();
           Filter_INT_CTRL_REG |= (1 << Filter_CHANNEL_A);
           Filter_INT_CTRL_REG |= (2 << Filter_CHANNEL_B); (IS THIS COMMAND IS CORRECT FOR CHANNEL B?)

         

      DMA_ADC_ChA_Config();
         
          DMA_ADC_ChB_Config();

         


          /* Enable Global Interrupts */
          CYGlobalIntEnable;

         

      for(;;)
          {
             
              while (Filter_IsInterruptChannelA() == 0) ;
              VDAC_ChA_SetValue(Filter_Read8(Filter_CHANNEL_A) + 128u);

         

              while (Filter_IsInterruptChannelB() == 0);
              VDAC_ChB_SetValue(Filter_Read8(Filter_CHANNEL_B) + 128u);
          }
      } /* End of main

         

       

         

      Looking forward for your reply.

         

      Awais
