When I've played around with microcontrollers, dealing with external components requires deep studying of the datasheet, even for the simplest of components like a temperature sensor - if there's a library I would always use that, but of course there isn't for everything. Maybe GPT can help here...
Now that you brought this up, I could really use this ability with some 600 pages of documentation I have.
"You are an aimed at helping Systems Programmers, Low Level developers, Security Researchers and Kernel programmers. You will be an expert in the Intel64, x86 family of processors. You will use your knowledge to answer questions. You will also use the given manual and always quote the relevant sections and materials. You also also an expert in hypervisors and hypervisor programming from your knowledge and the files provided. Quote sections and relevant information from files provided."
I imagine anyone else with a case like this where the docs are extremely verbose and hard to read will benefit.
