Hello,

so nobody can help me in showing the ric-files? :-(

Are you interested in my changes? ifdefs are not enough - I changed the icon file and the menu files.

You can download the firmware source on the mindstorms web-page. And on the iar web-page a free compiler version.

Have Fun.

About ric files: did you looked at cCmdWrapDrawPicture? Actually, it is supposed to be called from user code, not from firmware, so you will have problems to pass it arguments.

If you really wants to make a .ric file viewer in firmware, you should extract code from this function and put it in the display module for example.

Why not make your .ric viewer with a user program?

What is the exact name for the compiler?
Can you post a link?
Thanks, and have a nice day,

Yes, OK, but I do not understand how to do this...

Mh. OK, That would be more "compatible". But wanted to integrate the send / delete functions in the firmware... Those are in now :-) Only Run (view) does not work.

Do you know google? It is the first link after entering "iar mindstorms".

Can you please post the compiled firmware(.rfw)? Is it made from the enhanced 1.31?
How do you solder the stuff?

Mh, I thought about this again - and now I have an idea: I could write a user program, store it as hidden .sys-file and call this one from fw to show the graphic files.
Is there already a well done graphics file viewer? OK, I will search for it...

I do not have the source code of 1.31 or enhanced 1.31. I used the original LEGO fw 1.29 source as base for my changes. Those changes should easy be integrated in enhanced fw.
I do not solder anything - you only need to solder if you want to in circuit debug. But I only compile things to a binary and load this to the brick - thats it.

On the registration page I don't know what to fill in for some of the fields. Can you tell me what to fill in exactly or post the IAR installer or program in a zip?
Thanks, and have a nice day,

Do you have an idea on how to communicate the file name to view to this user program?

I have some ideas to call the function from firmware... but it will be dirty, I have to try it.

It works! Look at:

move RIC drawing code out of syscall wrapper
dirty hack to test RIC file drawing from firmware

The first commit split cCmdWrapDrawPicture in two parts, the second one is a really dirty hack to display .ric files in the "Sound files" menu ;-).

It is up to you to improve it!
