#CircuitPython2026

	CircuitPython 2026

	I accomplished many of the things that I mentioned in my 2025 post. A few that stand out in my mind are adding
	the tilepalettemapper module to the core, and gaining a much better understanding of register based drivers.
	Both of which allowed me to learn a ton. I also really enjoyed working on Fruit Jam OS and the games and programs
	that run inside of it.

	Looking forward to 2026: A few things at the top of my mind going into this year are MIDI and RAG (Retrieval
	augmented generation) based AI tools. RAG is a technique for getting better more specific and accurate results from
	LLMs about specific topics by looking up key pieces of information to give context to the LLM. I started to look
