dsh-mcu-lab

Verifying 8051 MCU assignments used to mean staring at Proteus and guessing whether an LED blinked at the right pin, or feeding a screenshot to a vision model and hoping for the best. Results were inconsistent and hard to reproduce. dsh-mcu-lab wires the whole Keil C51 build, Proteus simulation, and deterministic verdict chain directly into a DSH session, so a single natural-language prompt returns a PASS or FAIL backed by concrete evidence.

Under the hood it exposes five tools (mcu_run, mcu_build, mcu_sim, mcu_verify, mcu_list) backed by a pure-stdlib Python kernel. The verdict relies on two deterministic signals rather than screenshots: whether a hex file was produced, whether the simulator process CPU is advancing, and whether any failure marker text appeared. A free SDCC fallback covers the compilation step when Keil is unavailable. Every tool emits a single-line JSON result with a clear exit code.

Built for developers working through 8051 coursework or small embedded projects with Keil C51 and Proteus ISIS. No more switching between an IDE, a simulator, and a terminal; one DSH conversation handles compile, simulate, and verify, and surfaces the exact failure stage with a log tail when something goes wrong.
