given the following code that should print out the COG ram on serial port in PASM
serOutCog jmprel #+1
.counter long 1
mov .counter, #0
.loop
call #serCRNL
mov _serOutAddr_Arg0,.counter 'this will print the Address
call #serOutAddr
call #serSeperator
mov _serOutLong_Arg0,.counter 'Wrong. How to copy the value IN the COG register number .counter??
call #serOutLong
add .counter,#1
cmp .counter,#$1FF wc
IF_C jmp #.loop
ret
how to mov the value inside Memory location .counter to _serOutLong_Arg0 ?
_serOutLong_Arg0 is defined as long 1 in the COG
Comments
Use the ALTx instructions. The documentation has the details.
alts .counter mov _serOutLong_Arg0,0-0This works only with cog ram, right?
Tor LUT and HUB there are other ways, right?
Addresses will warp if i go over $1FF, right?
Yes, ALTx is for cog RAM only.
For LUT you use RDLUT/WRLUT, for hub you use all the other RD/WR instructions (and WMLONG)
yes
Thank you very much
Does this mean that the P2 has a built in Warp drive and you can activate it if you access the cogram behind $1FF ?
yes
But only after this instruction:
