[avr-gcc-list] stumped by my ATmega48 (again)

Hi all, I thought I was getting the hang of this Atmel programming, but after dusting things off a bit, I'm stumped again. I have a demo program from Matthew MacClary at Oregon State that toggles all output pins every three seconds. Pin 15 is hooked up to an LED on my breadboard, and when I inst

[avr-gcc-list] Missed optimisations when manipulating bytes

I was looking at the assembly generated from a program I'm working on, and it strikes me that there is a lot of scope for improvement in the register manipulation when mixing bytes and 16-bit words like in the code below. I've only tested using the latest winavr release (gcc 4.1.2), so maybe n

[avr-gcc-list] Boot vector setting for GCC

Hi, This may seem like a silly question, but how do i get AVR GCC to know what is the boot vector address for a device, which I set using the fuses (BOOTRST and BOOTSZ) on the chip? Abhijit K. ___ AVR-GCC-list mailing list AVR-GCC-list@nongn
