There should be a serial plug with solder pins on the back that you are supposed to hook up to the butterfly. I havnt done this, I only know because I'm reading "C Programming for Microcontrollers" all the examples are given on the butterfly. I use the AVRISP its $29 and just a basic thing that connects from serial port to AVR. I'm familiar with PIC and switching to AVR too. Many AVRs have several reference choices with the ADC including a 20x gain. These options are allowing me to take out the op-amp I was using with the PIC and ultimately save 60 cents on the manufacturing cost going with the AVR. >>Since the new PIC offerings haven't impressed me, I have been >>considering other options. >>ATMEL was kind enough to give me an AVR Butterfly.
