If you wrote it in straight-C it would be like 100 bytes) - if you want to see the source code for this, it's basically the Arduino file->examples->basics->blink demo with 1 as the LED pin. (Its a bit chunky as blink.hex's go as it has all the Arduino IDE stuff in there too. Microchip offers outstanding technical support along with dependable delivery and quality. However, you can do a basic test by uploading the following HEX file, which will blink the #1 LED once a second on and off. (MCHP) is a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, providing low-risk product development, lower total system cost and faster time to market for thousands of diverse customer applications worldwide. Programming in a Blink example For more details on using avdude and avr-gcc, you'll need to read a detailed tutorial or book on those subjects. To figure out where the nf is, open up a command window (windows: cmd, mac: Terminal, linux: rxvt etc) and type in avrdude -v. Arduino Programming Lessons Arduino Programming Tutorial To use avrdude a minor change must be made to to nf. That's easy to do! Target the Attiny85 as the chip used in avr-gcc, with F_CPU at 8MHz using the internal oscillator. I have the full code for the old atmel chip but want to bring the circuit upto date but don't have the knowledge of the c language. For more technical users, rather than using the Arduino IDE, they may want to program the Trinket directly with AVR-GCC as the compiler, vi/emacs as their editor and AVRdude as the uploader. I was wondering if I code convert the c code I have for a old atmel AT90S2313 to work on a Atmega328.
