The configuration of the UHK is unusually complex for a keyboard, composed of a number of items of different types, including keymaps, layers, macros, and the like. This is a supposed to be a short guide for the aspiring hacker. Let's get right into it!

The 3 representations of the configuration

There are 3 different representations of the configuration, each filling a specific purpose.

The JavaScript representation is optimally suited to be serialized as JSON, and saved to the file system, or transmitted over the network. As a plaintext format, it's human-readable and easily editable.

The TypeScript representation is structurally similar to the JavaScript representation, but it features strongly typed TypeScript objects instead of typeless JavaScript objects. It's meant to be used by Agent. Extensive validation is taking place upon constructing the TypeScript objects, ensuring the integrity of the configuration.

The binary representation is meant to be written to, and read from the EEPROM of the UHK. It's supposed to be very compact in order to maximize the use of the 32kbyte EEPROM space.

Data types

Each configuration item belongs to a specific type. The following types are available:

Primitive types are integers and string.

Compound types are composed of primitive types, and/or compound types.

Array type is a special compound type which is composed of a sequency of items of a specific type.
