in the loop, I had the same problem too, hope this helps  .

Yes, but IMO this post should be in the software section of the Forum, because IDEs don't always pertain to Microcontrollers. 

Guys thanks for the help, I was wondering if there was an easy way to produce sine waves,triangle waves, etc.

I was wondering if there was an arduino DAC library upcoming, that is under development?

I wanted to get some samples from TI but i don't own a company. I'm not sure if its legal to get the samples if you don't own a business. I'm only 13 and would like to know if i could get samples. I'm sorry if I didn't put this post in the right section.

Thanks

How do i connect a jtag programmer to my arduino mega 2560?

Well, i've decided to use the xmega128A1 ill keep u guys posted.

i was wondering how i could run a minecraft server with an arduino.

So,should i start looking at other micro controllers?

I would like it fast enough to have both atmegas to be able to run large i/o intensive programs at the same time.

The main obstacle is the limitations of the arduino software's serial speed.

So my choices are either I2C or SPI basically?

 would like to make a custom Arduino board using towo Atmega2560s. I was wondering how they could communicate with each other?

Okay i used the example sketch AnalogInOutSerial, but the fan stayed at full blast
