Multiple Cogs with PASM - Structure of pasm code

Jkane · 2014-05-22 08:40

Hello,

I have a questions

what is the structure for multiple cogs when using pasm

for example two pasm routines, 1 for each cog.

DAT (only one DAT)
ORG 0 'Begin at Cog Ram addr 0
head_interface
..... code (main and subroutines)
......variables
..... res
ORG 0 'Begin at Cog Ram addr 0
cog_33Mhz_clock
..... code (main and subroutine)
......variables
..... res

Spin code would be to start cogs

flag_HI := true
    flag_33MHZ  := true
    
    cog_head_interface := cognew(@head_interface, @flag_HI) + 1
   
  ' let Head Interface cog start
  
   ' waitcnt(cnt + (clkfreq / 1000))
    cog_33Mhz_clock  := cognew(@cog_33Mhz_clock, @flag_33MHZ) + 1
    ' let 33MHz cog start
  
    waitcnt(cnt + (clkfreq / 1000))
  ' wait for cog to stop
    repeat
    while (flag_HI == true)

I was just curious before i start making large changes.

regards

Jeff

ok,

got it, sorry, local variables vs global variables

all is well.

ORG 0 'Begin at Cog Ram addr 0
head_interface
..... code (main and subroutines using local labels (:label vs label)
......local variables
.....local res
ORG 0 'Begin at Cog Ram addr 0
cog_33Mhz_clock
..... code (main and subroutine (main and subroutines using local labels (:label vs label)
.....local .variables
..... local res

regards

Jeff
