I bought some blank Atmega328 P-PU's. Need to get the boot loader put on them. Bought the 16mhz crystal which wound up having 4 pins instead of the 2 i was expecting. Googled around and got that sorted. Got the 22 pf capacitors but never quite figured out where there go with this configuration. I discovered these instructions say that they are not compatible with UNO. Only older boards. I have 1 Uno and 1 Breadboard. I don;t wish to buy separate programming board if I can use the R3. Can someone point me to current directions that show how to use UNO R3 to program a Chip on a breadboard with the boot loader? I am finding all kinds of stuff but none of it is quite what I am looking for.
OK. Did that. Some questions and perhaps a problem?
-Found the right directions.
-Got the detector program talking to the solo Atmega on the breadboard. All F's.
-Got the Programmer firmware loaded.
-I have a 16mhz oscillator but right now I have it using the internal 8mhz crystal.
-I was able to successfully load the 8mhz "Lillypad" boot loader.
-I tried to load the 16mhz "UNO" version
All it says is "Fixing low fuse state..." then it seems to hang.
Question. Do I need to have it running on the 16mhz clock to load the 16mhz program?
If I pop that chip into the Uno, is there an easy way to just switch the clock speed after the fact?
Tried hooking up the 16mhz Resonator (4 pins). Didn't seem to play nice with the Atmega. Acted like no clock. So I hooked everything back up to the 8mhz internal and this time it allowed me to write the 16mhz "UNO" version of the boot loader without issue. Will test that out soon. Must have just been one of those things.
Hello every one i have Atmega328 ,Arduino UNO r3 board .when i power on and press reset switch pin 13 LED not toggle but continues on.And when i try to load firmware it give error avrdude: stk500_getsync(): not in sync: resp=0x00. i have found so many solution from other forum like uninstall driver and reinstall, 2)select proper COM ,3) select proper board , but i have not success yet, so Please any idea how i can resolve my problem . and is my board damaged,? when i try to load code on onther board it load success fully . so no driver or com problem are there. please help.
