LabWired allows engineers to test compiled firmware on simulated MCU boards (CPU and peripherals)

Andrii Shylenko’s LabWired is an MIT-licensed MCU firmware simulation core that runs compiled firmware against modeled CPUs and peripherals, captures UART and bus output, register state, and supports repeatable checks in CI. The simulator works on Arm Cortex-M0+, Cortex-M3, Cortex-M4, Cortex-M7, Cortex-M33 cores, RISC-V architecutre, and Xtensa LX6 and LX7 (some ESP32 parts). The main benefit of the project is speeding up firmware testing since doing some on real boards is slow. The hardware must be ready, then the firmware…
