A numeric expression must appear here
PostPosted: Wed Jan 13, 2010 6:56 pm     Reply with quote
Code:
  if(read_usb() == checksum)//if checksums match
   {
      delay_us(100);
      if(input(RXF)==0)//if more data in FIFO
      {
         delay_ms(5);//still have data in the FIFO but not exceed 100 bytes, read out. Or error!
                        while(input(RXF)==0)//clear the FIFO
                        for(count_bytes=0; count_bytes++; count_bytes=60000)
                        {
                                   if(count_bytes<=100);
                                    {
                                      send(0x66);//no error
                                      delay_us(100);
                                      packet_ready=1;
                                    }
                                    else %%%[color=red]A numeric expression must appear here  [/color]                                      {
                                             delay_ms(5);
                                             read_usb();
                                         }
                                     send(0xEE);//error!
                                     packet_ready=0;
                                   
                         }

                       
         
      }
       else
      {
         send(0x55);//no error
         delay_us(100);
         packet_ready=1;
      }
   }
   else//checksum failed
   {
      send(0xaa);//error!
      packet_ready=0;
   }

   strobe_SND();//send now
}


I have a problem with 'A numeric expression must appear here'. I checked the previous topics, there were no similar problem as mine.
I want to output many commands at once. So I revise the original c source code and add some lines. I was wondering if there are someone who can help me with that.
Thank you!

Do you notice what is at the end of the first line below that shouldn't be there?

Code:
if (count_bytes<=100);
           {
              send(0x66);//no error
              delay_us(100);
              packet_ready=1;
            }
