Accessing spin variables in a seperate COG using one pointer.

nummi · 2011-04-13 17:59

The variables are defined as such

  long Course
  long Speed
  long TimeStamp[2]
  long Flags
  long Latitude[2]
  long Longitude[3]
  long Date[2]
  long Satellites
  long Altitude

and the start function returns a pointer to course. Is there any way I can access these variables using just the pointer to course.
Thanks for any help!

Sure, assuming said address is stored in base_address then

a := long[base_address][4]

will access Flags (the 5th long in the array, 0..4).

When you say a separate COG do you mean passing variables to PASM? Otherwise the the variable as accessible in HUM RAM as long[@Course][0], long[@Course][1]... long[@Course][n] See "LONG" on page 127 in the propeller manual.
