 The firmware is located in the [avr](avr/) folder, and is entirely written in AVR assembly. Its size is currently under 2 Kibibytes, therefore it can fit onto an ATtiny25 and '45 in addition to the '85. It is assembled with the [avra](github.com/Ro5bert/avra) assembler by running the command `make firmware` or `make avr`, which puts the resulting `main.hex` file into the `bin/avr` folder.

+
+There is an example program provided together with the emulator in [C](examples/example.c) and [C++](examples/example.cpp). It is located in the [examples](examples/) folder and illustrates how to use the soundchip and the emulator API:
+
+- Initialization
+- Pitch control
+- Pitch calculation
+- Duty cycle control
+- Using noise and envelopes
+- Volume control
+- Noise generator control
+- Getting emulator output
+- Deletion
+
+The examples are not built by default as they have the `EXCLUDE_FROM_ALL` flag enabled, so you don't have to worry about them bloating your software. To build them, you have to explicitly select the `example_c` and/or `example_cpp` targets in CMake. The executables will appear in the `examples` subfolder of where the CMake Cache is.
