im curently using arduino as isp but i wondered!
i saw some ppl used the tccr1 and stuff thats avr code so can i write a completly avr code in ide and uploade it and stull write arduino code if wanted???
can i upload a avr app to the on board atmega328p and still turn it back? (not another the one on board)
and how can i upload a ARDUINO bootleader app to atmega on breadboard whit a arduino uno !? i tried arduino as isp for programmer and when done it uploaded on the onboard atmega!
I used the instructions on this link to upload a bootloader and to program a breadboard 328
You can upload code without using a bootloader in the same way that you upload the bootloader.
What is tccr1?
...R
TCCR is regsiter in AVR
for example TCCR1A
Timer Counter Register 1 A
i posted a whole explain but got broken link :((
When you mention that it is a register name I understand that bit.
But I still have no idea why you mentioned it in your original post.

i saw people using these avr codes can i write avr code in my arduino ide and upload to my arduino?? also if i do or remove my on-boards bootleader can i flash again?!!!!!
What avr codes are you referring to? Do you have a link?
What do you mean by "also if i do or remove my on-boards bootleader can i flash again?"
You will need to give a much more detailed explanation if you want to get a useful answer. I certainly can't guess what your brief synopsis means.

TCCR is regsiter in AVR
It is a very vague question, but my guess is that the answer is yes.
For example changing the pwm frequnce on an Arduino Uno could be done like this by setting the bits in register TCCR0A
int led = 13; // the pin that the LED is attached to
int brightness = 0; // how bright the LED is
int fadeAmount = 5; // how many points to fade the LED by
void setup() {
// To use Fast PWM on Timer 0Write this line in the setup function
TCCR0A = _BV(COM0A1) | _BV(COM0B1) | _BV(WGM01) | _BV(WGM00);
TCCR0B = _BV(CS00);
pinMode(led,OUTPUT);
}
void loop() {
analogWrite(led, brightness);
brightness = brightness + fadeAmount;
if (brightness == 0 || brightness == 255) {
fadeAmount = -fadeAmount ;
}
delay(30);
}

thanks! but wired thing happend i just found out about upload using progammer:D so i uploaded on breadboard atmgega 328p-pu whitout bootleader and ... it runed it perfectly !!! whitout bootleader but arduino code !!! 0_0 oh and i dont think so but can i programm the on-board which came whit uno havent touched atmega328p-pu whit avr remove bootleader and flash again and use as arduino???
remove bootleader and flash again and use as arduino???
I am not sure I understand the question, but you can burn a bootloader to your breadboard atmgega 328p-pu .
When you have done that it will be similar to the one sitting on your Arduino.
well the arduino board includes a atmgea328p whitout buying anything i ment uploading avr code and removing its bootleader but just never mind!
I sorry but I can't understand your questions. You seem to be trying to cram a lot of question into too few words. Try to tell us all about what you are trying to do using several sentences rather than just one.
If english is not your first language maybe you would get a better response on one to the other language sections of the forum.

If you are using an ATmega328 on a breadboard, you are using either the "Arduino as ISP" or a purpose-built AVRISP device to program it via ISP. Doing it this way, when you load a sketch onto it, the sketch is written instead of the bootloader, possibly overwriting it but in any case setting fuses so that on reset, it immediately starts the sketch instead of the bootloader; the bootloader has to all intents and purposes, been removed.
Having done so, you would have to use the "burn bootloader" function to re-instate the bootloader if you needed it for future use.
You can address particular registers using C++, or you can use AVR assembler code in the IDE (though I have not done so and consequently, cannot explain exactly how).

well i ment one on the arduino it self not breadboard but just np ! thanks anyway:))
btw uploaded IDE code without burning bootleader 0_0 worked!!!
