capture units of F2812 - naay...@gmail.com - May 28 6:33:29 2008



Hi all,

May I know which capture units corresponds to which PWMs of EVA and EVB?
I know that EVA has 3 capture units, CAP1, 2 and 3. Similarly for EVB CAP4, 5 and 6 and time
base can be chosen based on the values in CAPCONA/B registers.
Incase, if I would like to use CAP1 for capturing the rising edge of CMPR1 and CAP2 for
capturing the rising edge of CMPR3, How do I ensure that? Can any one of you answer me?

Many Thanks in advance. 
Naayagi

connect the hardware output pin of CMPR1 that is port8 pin9 on ezdsp board to the cap1 pin
etc
  this should do what you want
  but it can be done purely through software as well
