You can do it by using two bytes to store the 16 bit value.  The arethmetic is not hard at all.  What I want to do is this.

1.  Read a nibble

2.  Multiply that nibble by 100 (this is for pulse width modulation, calculating the high delay and the low delay) to get the high duration.

3.  Subtract the nibble by 1000 to get the low duration

Here is the Picbasic code:


[code]
high_dur var word 

low_dur var word 

  

here: 

  

high_dur = ra * 100 'multiply the ra channel by 100 to get high duration 

low_dur = high_dur - 1000 'get low duration 

  

high rb.0 

pause_us high_dur 

low rb.0 

pause_us low_dur 

  

goto here 

Thanks, kingneb
