Reporting program statistics

[alex]

Does anyone know of a good way to report statistics, like RAM usage and code space usage, using PBP? Perhaps an external program or an IDE exists which would do such a thing.

Hi Alex,

You can see how much RAM is used, and what your compiled program size is by examining the .lst file generated after you compile your code.

If your BASIC file name is test.bas, you should have a file named test.lst after compile. Open this .lst file to see RAM allocation, and compiled program code size.

It will look something like this depending on the PIC type, and how many variables you use;


RAM_START EQU 00020h
RAM_END EQU 001EFh
RAM_BANKS EQU 00004h
BANK0_START EQU 00020h
BANK0_END EQU 0007Fh
BANK1_START EQU 000A0h
BANK1_END EQU 000EFh
BANK2_START EQU 00110h
BANK2_END EQU 0016Fh
BANK3_START EQU 00190h
BANK3_END EQU 001EFh
EEPROM_START EQU 02100h
EEPROM_END EQU 021FFh
R0 EQU RAM_START + 000h
R1 EQU RAM_START + 002h
R2 EQU RAM_START + 004h
R3 EQU RAM_START + 006h
R4 EQU RAM_START + 008h
R5 EQU RAM_START + 00Ah
R6 EQU RAM_START + 00Ch
R7 EQU RAM_START + 00Eh
R8 EQU RAM_START + 010h
FLAGS EQU RAM_START + 012h
GOP EQU RAM_START + 013h
RM1 EQU RAM_START + 014h
RM2 EQU RAM_START + 015h
RR1 EQU RAM_START + 016h
RR2 EQU RAM_START + 017h
_EADD EQU RAM_START + 018h
_EDAT EQU RAM_START + 019h
_X EQU RAM_START + 01Ah

R0 to RR2 are PBP system variables. _EADD, _EDAT and _X are variables I created. From looking at my .lst file I know 27 RAM locations are being used by my program.

Program code size is also shown in the .lst file. Scroll down to the last line, and look at the hex number on the left.


+ 00D0- 0008 return
00D0h shows that my compiled program size was 209 words.

If you use an editor like MicroCode Studio, it will show the compiled program size on the lower left of the screen.
