Some programs are breaks. (I am tired and am absent)

2008-07-29T13:32:44+02:00

I am assigned to a different result being given and do not doubt it.
My age has exceeded 60, but my technology and knowledge are still unripe.
Perhaps I think with the result that I be accompanied and forget some kind of options and compile. （I am unripe in optional contents）.
Like you, I wish that I want to arrive at a satisfactory result early.

A story changed and went to Vienna by a sightseeing tour six years ago.
I asked an unknown person the place of "association of music friend" in Japanese.
The person taught it in English.
Association of music friend was near immediately, but was under construction.

I asked Grandfather of "the key shop" a key elsewhere and bought "a key" and "door metal fittings".
It was Japanese and German then that two people talked.

About the boot loader

2008-07-29T12:29:13+02:00

Did you choose the same options for the boot loader (same emulation level) as when you do a "make allhexfiles"? Other than that, you might use a different version of avr-libc (although I doubt that this make such a great difference).

Is there any hint?

I tried the above.
However, I did not become "2028".

About the boot loader

I compiled this with gcc 3.4.6. If you use WinAVR, you must use a rather old version (before the switch to gcc 4).

About size.

2008-07-23T11:54:24+02:00

You compiled it.
It is the firm ware which I download it, and unfolded.
Going astray "size mega168_12mhz.hex"
text data bss dec hex filename
0 2028 0 2028 7ec mega168_12mhz.hex
It is displayed.

I downloaded it.
I did "make" of "USBaspLoader.2008-02-05" in "WinAVR-20080512" and compiled it.
"main.hex" is displayed as follows.
"size main.hex"
text data bss dec hex filename
0 2392 0 2392 958 main.hex.

As for it, memory consumption changes.

Did you compile it in "WinAVR", which version?

For the Pin Change thing, see the end of this thread:

http://forums.obdev.at/viewtopic.php?t=1067&start=15

This was on the tiny45, but it's still an example for using the pin change interrupt.

A different issue: The osccal routine is too big for a 2 k boot loader. Your code size is ~ 2.5 k, too much for the boot section. You'll probably find a different way to calibrate the oscillator or otherwise reduce the code size.

Is the result good in this?

2008-07-22T15:27:02+02:00

Thank you for an answer.

I have made a mistake in the name letter of this forum.
In addition, the ID name has been wrong, too.
Is there the method to redo being right?

I did not find the item which fell under "1".
I validated "2" and got a result of compiling it.
However, I was not "three" negative results in that, but watched a slightly bad part.
Do not I need to pay attention to this item?

I intend I add "OSCCAL", and to try RC12MHz.
I do not know the position that is necessary for the addition.

I'm not sure I understand what you are asking...

Looking at the code: You still have those defines commented out. But I see that you have already found the appropriate values for the defines. I have not checked them, but you obviously understood the concept.

Regarding interrupt edge sensitivity: The driver should work with any edge (rising / falling / both). Just try it.

About the direction of the change

2008-07-22T06:36:52+02:00

I examined it about an interrupt.
I start an action by the upward movement of the "INT0" signal by the original.
I catch even the change of either direction in "PCINT8" which I hope for.
How do you do the handling of this case?

The later change

2008-07-19T06:24:07+02:00

I made the first aim "mega168p, 12MHz, D+_PC0, D-_PC1, the boot loader" which I used "OSCCAL" for.
I compiled original "EasyLogger.2008-02-28" in avrstudio4 for the study and I compiled it replacing with "mega168p-12MHz" to be next and succeeded.
When add "OSCCAL" afterwards; "main.c:" 250: error: static declaration of 'calibrateOscillator' follows non-static declaration "libs-device/osccal.h:" 44:00 error: I became the error of previous declaration of 'calibrateOscillator' was here.
I stopped it once here and I compiled original "USBaspLoader.2008-02-05" "mega168p-12MHz" and succeeded.
It is changed "D+_PC0, D-_PC1" to be next
#define USB_CFG_IOPORTNAME C
#define USB_CFG_DMINUS_BIT 1
#define USB_CFG_DPLUS_BIT 0
/* #define USB_CFG_PULLUP_IOPORTNAME C */
/* #define USB_CFG_PULLUP_BIT One */
I changed を of it and succeeded in compiling it.
When add "osccal.c" just before "int main(void)" in "main.c" afterwards; "main.c:" (.text+0x524): I become the error of undefined reference to `usbMeasureFrameLength'.
