i have the version of 2005
 I found a copy of the changes made : timer.h has been deleted from the package
:
Removal of all items marked as deprecated in the past, namely:
all header files from the base include directory, as they have been moved to the avr/ subdirectory long time ago (e.g. <io.h> is now <avr/io.h>),
deprecated macros and functions (sbi, cbi, inb, outb, inp, outp, inw, outw, BV, PRG_RDB, eeprom_rb, eeprom_rw, eeprom_wb)
<avr/timer.h> removed completely, as it was bogus and not really useful at all
<avr/ina90.h> and <avr/twi.h> have been moved to the new <compat/...> include subdirectory,
The following new devices are supported:
ATmega165
ATmega325
ATmega3250
ATmega645
ATmega6450
ATmega48
ATmega88
ATmega168
ATtiny13
ATtiny2313
AT90CAN128
realloc() is now implemented,
the boot API has been changed in a way that is incompatible with the 1.0 API,
the delay API has two new functions added to allow the specification of delays directly in microseconds, or milliseconds,
documentation changes: a newer version of Doxygen is used; Unix-style manual pages are now generated as part of the documentation; a helper script named avr-man can be used to display these manual pages,
a single unified Copyright now applies to all files in AVR Libc.

I can't compile your software it gives the error:
delay.c:16: error: `CK' undeclared (first use in this function)
and
delay.c:20: error: `TCNT0' undeclared (first use in this function)

I think timer.h is to blame ... i can't find it anywhere in the avr-libc  include dir
can you confirm my suspicions ?
and do you have an solution?

sorry for this question
I usually use imagecraft

U use the feedback network with the 1 Mohm for stability?
isn't a schmitt trigger configuration a better solution?

hello vitat...

Is it possible to changes the values  10Kohm to 1Kohm and the 1Mohm to 100Kohm  thus keeping the amplification at 100 times...
or would it put too much strain on the ip-bus / can driver?

thank you..

I have build the converter with a PIC processor.
I read on this forum someone had developed a code for a PIC processor.
Does anyone want to share his code with me?

isn't there any fancy solution, perhaps someone opened a cd-changer to see which chip is inside there. this is a kind of work around....

why is the RXD of the PCA82c250 not connected? but are you using a comparator for the rxd function ?
is the chip not fully compatible with the IP protocol?

thank you
