Finding variables in RAM

[Charles Linquis]

I need to pass large arrays between PBP and ASM - larger than the BANKA limit. If I define an array in PBP, what is the best way to find the start location (in RAM) of that array in ASM? I'm using an 18F8723.

I guess another question could be - does CH?RP work for RAM variables?

I ran a test. It does. Problem solved.

Charles,

Since you are using an 18F. You might want to use the FSR's and the LFSR instruction to access your arrays.



LFSR FSR0, _MyArray
MOVF _Idx, W
MOVFF PLUSW0, _Destination

Thank you Darrel. I'll try it tomorrow.
