Hello!
I need som advises here!
I have Arduino Mega 2560 and Arduino Uno Rev 3. And i have ATmega8 and ATmega328.
I have been searching for how to create an Arduino of an ATmega8 or ATmega328. But have not find any manuals who i can trust.
Many people who are using Arduino seems not to follow the standard.
Anyway!
I have some questions.
Can i use this manual, who are for ATmega328 CPU, to burn a bootloder + program via Arduino UNO to the ATmega8?
Yes, you really need the 16MHz crystal and caps if you want to make an "Arduino." It's part of "the standard."
Nick Gammon's tutorials and tools ( Gammon Forum : Electronics : Microprocessors : Atmega bootloader programmer ) are the most complete.
For a completely stand-along mega8 project, you might want to avoid programming the bootloader, and just use a "real" device programmer to put your sketch onto the avr.
i cannot trust old software on my Arduino.
Then you'll have to learn how this stuff works from "original sources" like the Atmel datasheets and app notes, and the more technical websites like AVRFreaks, so that you can figure out which things you can trust (and why), and which things have changed to make older tutorials untrustworthy, and so on. It will be MORE DIFFICULT than using an Arduino.
I'll have to express a certain amount of frustration about the large number of people I see who are essentially complaining that no one has made a bare AVR chip as easy to use as an Arduino. Arduino's focus has been on making the AVR easy for people to use (and they've done pretty well.) One of its attractions is that you CAN build simpler boards that use the same infrastructure; it's just an AVR, and a C compiler, and an editor. But to use it that way, you do have to learn A LOT more than you need to know to use an actual Arduino. It's not a horribly large amount, total, but it is MORE. Nick or I can throw out a comment like "you can use avrdude from the command line once you've installed the correct device drivers for the usbasp programmer" and it SOUNDS easy, but in the modern world a lot of people have never used the command line, installing device drivers is considered to be among the most difficult tasks you might do on your computer, and 90% of usbasp programmers are clones that may or may not be compatible with ... anything. (the really annoying people are the ones that have decided that Arduino is "too silly", and they want to learn REAL C and REAL microcontroller programming, and then go on to immediate ask a question that indicates that they really aren't ready for REAL C on REAL microcontrollers. Sigh.) rant, rant, rant...
So here's a quiz.
Do you have a mega328 or a mega328p? Do you know why the difference is important?
You said you want to program a "bootloader+program" - why?
You CAN run a mega8 or mega328 without the crystal. What would you have to change to have an arduino sketch (say, Blink) still run correctly?
Hello!
I found this manual and i gonna follow it!
But this manual is for ATmega328P-PU and i have ATmega8-16PU
Can a use this manual for ATmega8-16PU?
Nobody knows?
Why are you ignoring the reply you got from 'westfw' ?
