Different people have different preferences.
Personally, I prefer to write code on EmBitz for hardware rather than using the simulator (though I've only written one game and a few test programs for the PEX tutorials).
For your first program, you'll probably find it easiest to modify the "hello world" example on EmBitz. There's some other examples as well.
All you need is a copy of the PokittoLib and EmBitz. Then you open the
.ebp with EmBitz and navigate to the examples
Then you can find the compiled code in
Then you connect your Pokitto, delete the
firmware.bin and copy the
helloworld.bin file to the Pokitto.
