This example illustrates how one can communicate with the simulated AVR
using its USART. The other end of the communications line is stdin/stdout,
so you can simply interact with the simulated AVR by typing into the
terminal you used to start it with.
The firmware provided can be uploaded to real hardware as-is and should do
just the same when accessed through a serial terminal. This is an important
point, because in main.c you can see how few tweaks to the original code
are required to allow interacting with a simulated run. All of these tweaks
don't alter the binary actually executed at all.
Building and running the example:
- Have SimulAVR built, default configuration options are fine.
- Go to examples/simple_serial (here).
- Build the example:
make
- Run the example:
make do
- Upload the example to and run it on real hardware (this isn't exactly
flexible, yet, it might require some tweaks to the Makefile to match
/your/ hardware):
export SERIAL_AVR=/dev/<your device here>
make program
gtkterm -p $SERIAL_AVR -s 19200
Interaction:
Well, extremely simple. It's a code example, after all. Type characters and
the characters will be sent back with some extra text. That's all, I hope
this fuels your imagination.
