TM4-Traffic-Controller

Embedded software and supporting tools for a traffic-light controller running on the Texas Instruments Tiva(TM) TM4C1294NCPDT microcontroller.

Refer to documentation in the documentation folder for Requirements, Architecture and Design, and Testing:

Summary

What: Real-time traffic light controller firmware, a desktop prototype, and test/data tools.
Hardware: TI Tiva TM4C1294NCPDT (see tm4c1294ncpdt_startup_ccs.c, tm4c1294ncpdt.cmd).

Repository layout

main.c — firmware entry point and application logic.
tm4c1294ncpdt_startup_ccs.c, tm4c1294ncpdt.cmd — startup and linker script for CCS.
prototype/ — desktop prototype implementation (prototype.cpp).
testing/ — test harnesses and scripts (testing.py) and data/ with sample CSVs.
documentation/ — requirements, architecture and testing documents.

Build & flash (TI Code Composer Studio)

Open a CCS project and include main.c, the startup file, and the linker command file tm4c1294ncpdt.cmd.
Build in CCS and flash using the supported debug probe (e.g. XDS). Adjust project settings to match your board/target.

Run the prototype locally

Compile the prototype (requires a C++ toolchain):

g++ -std=c++17 -O2 prototype/prototype.cpp -o prototype/sim ./prototype/sim

Testing

See testing/data/ for sample input CSVs used by the test harness.
