**USB Type-C Power Delivery Module for Go**

At the moment, only sink functionality is implemented. Sink refers to a

power consumer. You can use the module to request specific voltage and

current from USB-C power source such as wall adapters, power banks and

more.

Goals:

 - Easy to use, understand and modify.

 - Familiar to Go programmers.

 - Efficient resource utilization so it can run on microcontrollers and

   in embedded environments.

 - Compatibility with various port controller hardware.

Non-goals:

 - Following standard word for word.

 - Implementing all PD functionality.

There are examples in the [examples](./examples) directory to get you

started.

*Note that the timing requirements of PD messaging is rather strict. As

such, in environments where communication latency is high, it may not be

possible to implement a working program. For example, on a linux desktop

using the MCP2221 I2C bridge to communicate with FUSB302 PD port

controller, each I2C transaction latency is too high (~10ms) for things

to work. Your mileage may vary.*
