Number of Cycles for _divmodsi4
I did the same. An interesting result is when the divisor is 0. I expected a quick exit but it counted 720 cycles. Similarly a divisor of 1 gave 620 cycles. Perhaps the authors...

AS6 Output Files
You might use elf rather than hex if you want a single file containing code, eeprom, fuses, lock bits. Otherwise always use hex for code and eep file for eeprom.

attiny87 versus attiny167
It's software compatible in the sense that you can take the same source file, just change the build target between 87 and 167 and rebuild. Given that this only takes a minute I...

Arduino libraries with AT90USB
Note also that for the USB specific part you will probably use LUFA so you also have to bear in mind how other code will interface to that.

LCD not displaying character in ATMega16
Why not use the LCD code that came with your compiler simply to verify the electronics?

Atmega328 and LCD issues
I guess you missed Steve's comment above that avr-gcc already comes with working 4 bit LCD code?

Even the "second or two of compilation time" really means one or two seconds the first time lcd.c is compiled to lcd.o because after that it's unlikely to change so won't be...

Char to graphic screen
I'd stick to fixed width fonts (think Courier on Windows or even the [code] font here). While proportional are do able by keeping widths with characters consider how complex...

at90usb162 internal flash question
If you use LUFA does that suggest you use avr-gcc? If so then look at boot.h and the BOOTLOADER_SECTION macro in particular, use with a - - section-start=.bootloader=0xNNNN in...

no way to compile code for atxmega256a3bu w/ avr-libc
Quote: Anyway, my issue is not with avr-gcc, but with avr-libc. As I said above (it was me, really) under GPL Atmel really should be publishing patches for the AVR-LibC they...
