How to change DIN / DOUT Bit order?

[/code]

and attached a precompiled .hex file

Sorry,

I tried that yesterday without success, but I am not sure.

I test it with dout_buttons_v1c application and the result is the same as with unmodified mios_srio.inc

SR# 1 Pin#0 0x00 let lit a LED on physical Pin 7 (QH) on a 74HC595

...

SR# 1 Pin#7 0x07 let lit a LED on physical Pin 15 (QA) on a 74HC595

that are the right results for standard mios_srio.inc I guess.

but I get this for both cases modified and unmodified.

I have also tried to change the DIN bit order with same effect.

It seems that nothing changes.

What about the applications, are there any changes to make?

I tried that yesterday without success, but I am not sure.

So, you compiled MIOS by yourself and uploaded it to your core before uploading the application?

If this modification hasn't caused an effect, then I assume an handling error (please describe more exactly what you did to clarify the issue).

Since I assume an handling error, I attached a precompiled .hex file so that you can easily compare the results.

Before continuing with speculations, could you please give me some feedback if the .hex file I gave you is working at your side.

There are no other changes which are required, it's really straightforward.

Best Regards, Thorsten.

Yeah,

I wondered by myself but the precompiled Mios Version do the same.

I have also think about a upload failure, but the precompiled Version shows no longer the "READY." Message first.

And so I think all is gone right by uploading.

I will now have a try with Linux and MIOS Studio 9 to upload, because I can't use the core feedback feature with my old Win 98 :D

and Studio 7.5

Later more ...

Shit I can't believe that.

I'm so sorry

Yes it works, now.

MIOS wasn't uploaded right to the core, I don't know why.

Most changes (try to learn assembler the last days :D) on MIOS or MB64 takes a small effect and I thought the code was proper uploaded to the core.

Thanks for the help Thorsten and best wishes for the coming decade.
