'[PIC]: Optama C-Compiler tested'

Hello Piclisters,

some time ago i read a post from a list member wondering if the Optama
Compiler is a new design or if it is probably a commercial version of the
shareware c2c compiler.

Meanwhile i had a closer look at it and therefore can state that the Optama
C Compiler is absolutely not more and not less than the C2C plus Compiler
version 4.007 from Pavel Baranov. (his own latest release) Both of them
produce absolutely the same obj code from a given source.

With 2 (3) differences: Optama comes complete with gpasm.exe and sasm.exe
(which both are freeware) and it comes with a complete set of include files
for all Pic4s. They are exactly the same ones that come free with MPLAB.
(means they are copied out of the MPLAB package)

And of course there is another difference: Optama is 8 times the price than
the C2C shareware package was selled before.

Btw. The c2c package is still available at Baranov4s homepage. At least at
the moment.

gpasm is not Freeware!
It's licensed under GPL. Are they distributing the source along with
the executable?

Thanks for the notice Scott, i didnt know that.

nop - there isnt any source code included, just the binary gpasm.exe.
It says to be derrivated from version 0.9.4.
You can also find the gpasm.exe included with the DEMO wich is freely
downloadable from http://www.kanda.com.

If they modified it and then provide the excutable without a means to aquire
the source that is a violation of the GPL. If they did not modify it they
could propably just point to the place where they got the source. BTW gpasm
is GPL, isn't it?

Like I said previously Kanda says that the source is available.

I work at Kanda, well I work at home, and I emailed the developers in charge
of the project and they say the source is freely available. There is an
optama website in progress I think the plan is for this to contain updates
and stuff. I can't say much more cause its not my project. I'm an ISP
developer :) When I find more info I'll post to here to let people know.

We are interested to hear peoples opinions of the compiler and any changes
or enhancements that it may be in need of. Customer feedback is the only way
we can discover this sort of stuff. We are very new to the compiler software
market. Any posts I see that are relavent to the Optama compiler I'll pass
onto the developers.

I'm lurking on this list because I'm learning pic stuff in my spare time.
I'm not spying for Kanda so feel free to have your say, I won't tell anyone.
Looking at previous posts and the archive you aren't afraid to have your
say. It makes a refreshing change...

Hello PICLIST all,

i am new to the list and to C programming language.
In my test about the Optama C-compiler DEMO i came across a couple of bytes
within the OPSXPICDEM.EXE looking like:

ff 52 14 3d c8 00 00 00    or in english:

call    [edx+14]                ; ?
cmp    eax,000000c8        ; 200 ??
jle      004a753d               ; !?

Since i am not familiar with assembly language - i programmed all my PIC
project with Picstart Plus until yet - i cannot understand what the meaning
of this lines might be. Is it eventually for 200 users max or something.

Could any list member please explain for me. Thanx.

Brain Lite

ps. I also thaught about asking http://www.kanda.com , but i am afraid they
probably wont tell me.

Hello List this is Brain again,

i did change those strange bytes to look like:

ff 52 14 3d ff ff 00 00

and i really believe that the Compiler will now support 65.535 Users, wow
that is quite a lot people.

But unfortunately i cannot further test this cause i am all alone in here.

Something is very confused here.  The disassembled instructions you show are
not for a PIC.  They are 80386 (or higher) instructions.

What we see here is an unsuccessful hack of the installshield installer file
:)

If thats what the guys told you, seems they didnt had a hex editor handy.
Or if they had, they probably didnt found the manual for it.  :)

ff 52 14 3d c8 00 00 00    ; poor demo.exe
ff 52 14 3d  ff  ff  00 00    ; could also be less since there are no 64kb
                                        ; Pics available.

Btw: Even success is relative. It will not make a hitech-c out of it. ;-)
