EEC V file conversion

B302 is good.

# leave out that line.

V4.012 DIR for RZASA consolidated from various sources.

Read the details in the header for {?}.

I apologize, I missed the correlation of the data sources to the line numbers. I thought you were just numbering the data sources in list format. I feel stupid now, LOL. Thanks

B302 is good.

Great, thanks for verifying that for me. I will add that in as an Rbase value. I am surprised that SAD missed that one as it seems to be in the code very frequently.

So there is a section in both OMAE2 and RZASA that I am hoping you can take a look at and see if you can figure them out. Both look very similar and neither are disassembled very well but both look very similar...

OMAE2 about line 1A1FE may start sooner and RZASA line 19C99, also may start sooner. and it goes for a good little while matching up pretty close. Can not figure out if they are functions, tables, or structures, or maybe something else. Little above my knowledge base. Thanks

Also I think the below may be tables, could you confirm for me please???

Code: Select all

OMAE2 code line  -  ADDR pointer
L_99DBC          -  1873E
L_99E0D          -  18806
L_99E5E          -  188CE

Of course now that I am looking at it closer they may be functions and swTb34EPPH in RZASA also looks like it should be a function???

[jsa]

For RZASA L19C99 I've given it a structure command and ?? in its comment because it's wasn't clear at the time.
What code have you got from LST that accesses L19C99?

[BOOSTEDEVERYTHING]

I don’t have any code specifically for 19c99. Just a pattern I noticed in both lst files. I’ll do some more research on it and hopefully I can find something that calls for an actual address. Wasn’t sure if the areas in the lst files were just needing to be defined as something to show up somewhere.

[jsa]

Needs some time spent on it to work out the contents of various temporary registers and the purpose of the sub.
RZASA

Code: Select all

0803b: b3,41,99,9c,40     ldb   R40,[R40+9c99]   TMP7L = [TMP7L+19c99];
0807d: b3,45,99,9c,44     ldb   R44,[R44+9c99]   TMP9L = [TMP9L+19c99];
080d3: b3,3d,99,9c,3c     ldb   R3c,[R3c+9c99]   TMP5L = [TMP5L+19c99];

OMAE2 L1a1fe does look like the start of the equivalent structure.
OMAE2

Code: Select all

0b8fd: b3,41,fe,a1,40     ldb   R40,[R40+a1fe]   R40 = [R40+1a1fe];
0b93f: b3,45,fe,a1,44     ldb   R44,[R44+a1fe]   R44 = [R44+1a1fe];
0b995: b3,3d,fe,a1,3c     ldb   R3c,[R3c+a1fe]   R3c = [R3c+1a1fe];

Solve one...both solved.

From the comments in DIR for LU Subs, tells you what the registers hold for table lookups.

###### Word Table Lookup Subroutines: R3C Tb_Addr Reg, R34 Column Input Reg, R36 Row Input Reg
###### R38 Column Quantity Input Reg, R3E Output Reg

The table address is loaded into R3C before a table lookup sub call.

swTb34EPPH is a table.

Is there a way to define a table without knowing the exact size and purpose of the table? If so, could you please give me an example of how the best way of doing so would look? Thanks again for all of the help, this new DIR file has helped me find a good bit more in the OMAE2 code. Going to switch back to the READ0 code soon and see what else I can find there to get me further along to the path of building a good DEF file for my dads truck.
I have also found some of the fan code in the OMAE2 code. Hopefully I can make all of that work on my truck when I get it back up and running again. Also may give me something to transfer over to the READ0 code to use on my dads truck. I am also going to start building an "adapter" harness for my dads truck to hook up a second pcm to try the fan code with. I may hook up some leds for a visual indication the the fan code is working as designed before I go to an actual fan. Thoughts?

[jsa]

Yes. There are examples of tables in RZASA defined without a known purpose. Row and column count needs to be known. Have a look at the RZASA lst with cmt file and check out the table lookup subs.

LEDS, yeah why not.

[jsa]

After looking at the info I've guided you to review, paste up the line of code that sets the column count for swTb34EPPH.

[BOOSTEDEVERYTHING]

Wow!!!! I do not understand this as well as I thought I did. The table lookups are a bit confusing now that I am looking at the big picture of how the table actually functions. I think this is the code you are referring to?

Code: Select all

09777: ad,08,38           ldzbw R38,8            TMP3L = 8;        = (Table Width) 8 COLUMNS

After looking at all of this, I just want to make sure I am viewing it correctly?

The code uses all of this to actually get through the table to get the end value, correct? I copied over the applicable code to a new document and will try and make some notes on it and post it back up for you to review and let me know if I am interpreting it correctly, if that is ok? One question I do need clarification on, the code uses the functions to set row and column lookup values, correct?
