Just my EUR 0.02: The choice of these names is probably very historic, and unless one of the senior avr-{gcc,libc} developers tells us, we can only guess about the reasons. My...

ADC in AT90S8535
I've just upgraded that again to use the new IO syntax. This has not yet been tested, but the resulting binary and hex files compare identical, so it should be correct. I see...

ADC in AT90S8535
I've always meant to make this slightly more enhanced version of the simple demo project publically available, so here it is: This has only been...

AVRDude STK oscillator
You cannot tune AVRdude that way. However, have a look into the archives of the AVRdude mailing list. There has been some work recently to fix timing issues under Windows, but the...

Boot.h and AVR GCC 3.2
Too old tools. Please use WinAVR.

bitfield to specific memory location
Just a hint: if this refers to some form of memory-mapped IO (as opposed to real SRAM), better declare the pointer to be pointing to a `volatile' object.

TWI Trouble
I was referring to twitest/twitest.c in avr-libc. Unlike the datasheet, it's a complete functional example that has been tested in real world. It should answer at least some of...

TWI Trouble
Did you have a look at the TWI example code?

Most of the work is already done in . Left as an exercise for the reader: some preprocessor magic to calculate the required timing divisor out of your CPU frequency.

Varaible gets reset on output to Serial :S AVR8515
OK, but then don't expect anyone else to examine what sending 0xD8 to UCR might do. After all, it's you who wants the help. I wouldn't seriously write it that way even for myself...

Varaible gets reset on output to Serial :S AVR8515
Perhaps you start first by using symbolic constants for all your magic numbers, so anyone else could actually follow your program at all... Obtw., inp()/outp() are deprecated.
