# The `rules.mk` File
This is a [make](https://www.gnu.org/software/make/manual/make.html) file that is included by the top-level `Makefile`. It is used to set some information about the MCU that we will be compiling for as well as enabling and disabling certain features.

?> This setting will stop the ability to demo using battery packs.
```c
#define SPLIT_USB_TIMEOUT 2500
#define SPLIT_USB_TIMEOUT 2000
```
This sets the maximum timeout when detecting master/slave when using `SPLIT_USB_DETECT`.
```c
#define SPLIT_USB_TIMEOUT_POLL 10
```
This sets the poll frequency when detecting master/slave when using `SPLIT_USB_DETECT`
