> For the complete documentation index, see [llms.txt](https://alex-robenko.gitbook.io/bare_metal_cpp/llms.txt). Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://alex-robenko.gitbook.io/bare_metal_cpp/peripherals/other.md). # Other There are many other peripherals and/or protocols (such as I2S, USB, one wire). The implementation and the main concepts should be pretty similar to the peripherals covered so far. At this stage I do not plan to do it in this book. At least not in the near future. Various micro-controllers may also support [DMA](http://en.wikipedia.org/wiki/Direct_memory_access) access to some peripherals. In this case the `Character` **Driver** that was covered in [UART](/bare_metal_cpp/peripherals/uart.md) chapter must be replaced with some kind of `Block` **Driver**, that will allow issuing of multiple read/write requests at the same time and will receive only "operation complete" notifications from the **Device**. I leave implementation of it as an excercise for the reader. At least for now. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://alex-robenko.gitbook.io/bare_metal_cpp/peripherals/other.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
