Programming
The MC-NANO can be programmed with the Arduino™ software (download). Select "Arduino™ Duemilanove or Nano w/
ATmega328" from the Tools > Board menu. For details, see the reference and tutorials.
The ATmega328 on the MC-NANO comes pre-burned with a bootloader that allows you to upload new code to it without the use of
an external hardware programmer. It communicates using the original STK500 protocol (reference, C header files).
You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header; see
these instructions for details.
Automatic (Software) Reset
Rather than requiring a physical press of the reset button before an upload, the MC-NANO is designed in a way that allows it to be
reset by software running on a connected computer. One of the hardware flow control lines (DTR) of the FT232RL is connected to
the reset line of the ATmega168 or ATmega328 via a 100 nanofarad capacitor. When this line is asserted (taken low), the reset line
drops long enough to reset the chip. The Arduino™ software uses this capability to allow you to upload code by simply pressing the
upload button in the Arduino™ environment. This means that the bootloader can have a shorter timeout, as the lowering of DTR can
be well-coordinated with the start of the upload.
This setup has other implications. When the Nano is connected to either a computer running Mac OS X or Linux, it resets each time
a connection is made to it from software (via USB). For the following half-second or so, the bootloader is running on the Nano.
While it is programmed to ignore malformed data (i.e. anything besides an upload of new code), it will intercept the first few bytes of
data sent to the board after a connection is opened. If a sketch running on the board receives one-time configuration or other data
when it first starts, make sure that the software with which it communicates waits a second after opening the connection and before
sending this data.
