Assembly Firmware For Microcontroller Prototype

I’m moving a new embedded concept from paper to proof-of-concept and I need lean, fast firmware written entirely in Assembly. The exact device is still open—we’re weighing AVR, PIC, and ARM—so part of your first task will be to advise on the most suitable MCU and tool-chain for the job.

Once the silicon is chosen, I’ll provide the electrical schematic and the functional requirements; you translate those into tight, cycle-efficient code, supply a ready-to-flash HEX (or BIN) file, and walk me through any fuse or configuration-bit settings that matter.

Deliverables
• MCU selection rationale with part numbers
• Fully commented Assembly source files
• Compiled firmware image (HEX/BIN)
• Brief setup-and-flash guide plus inline documentation

I’m preparing hardware now and would like to commit to a coder who enjoys getting close to the metal and can iterate quickly as the board spins come back. Let me know your relevant Assembly experience and preferred debugging tools so we can get started right away.
