Reviewing both files, 90% of porting all programs from AVRStudio to Arduino is simply making sure header files have
angle brackets <> and that main() is replaced with loop() and that a function setup() is added to your program. The
setup() function can be empty, but will be called before loop() is, thus it’s a nice place to put initialization code.
Personally, I just think of loop() as main() and leave it at that.
Serial I/O Libraries
The last little porting tip has to do with serial communications. We wrote serial UART libraries for the Chameleon AVR that
are stored in CHAM_AVR_UART_DRV_V010.C|H. You have seen these in the API overview section. However, Arduino
has a built in serial class that you can review here:
Thus, you can use our library or the Arduino library, if you decide to use one or the other then porting is a simple matter of
changing a couple function calls, below in Table 27.1 is a quick list of the function call mappings for the serial calls.
