I’m finalising a vehicle-tracking PCB that centres on the Renesas RL78/G13 R5F100FEA MCU and I’d like a firmware specialist to take it from bare silicon to a field-ready prototype. Core objective • Develop clean, well-documented C code that handles the MCU start-up, peripheral initialisation and the full real-time location tracking loop. • Integrate a GPS receiver and a cellular modem over UART/SPI, package NMEA data, and push coordinates to our cloud endpoint with minimal latency. • Drive an on-board SD-card controller so raw logs are mirrored locally in case connectivity drops, using a simple FAT file structure. • Keep the design power-aware: sleep modes, clock gating and watchdog strategy are essential for battery life. Helpful context Hardware is already routed; I can share PDFs of the schematic, layer stack-ups and the Renesas E2 studio project shell. The board uses: – UART0 for GPS, UART2 for modem – SPI0 for the SD interface (3.3 V flash footprint reserved if you prefer) – A few GPIOs for ignition sense, LED status and a buzzer Deliverables 1. Compilable E2 Studio project (.c/.h, linker script, start-up). 2. Brief read-me covering build steps, fuse settings and in-field firmware update procedure. 3. One-week post-handover support for bug fixes discovered during bench or road testing. Acceptance criteria • On bench with my hardware the MCU must acquire a GPS fix and publish a JSON payload to the test server within 10 seconds of power-up. • SD card must hold identical coordinate/time stamps for every published sample. • Average sleep current (ignition off) ≤ 150 µA at 12 V input. If you’re already comfortable with the RL78 toolchain, Renesas peripheral libraries and low-power embedded networking, this should be a focused engagement. Looking forward to hearing how you’d tackle it.

Hi there, I can develop clean, well-structured C firmware for your RL78/G13 (R5F100FEA), covering full MCU bring-up, GPS (UART0), modem (UART2), and SD logging over SPI. The design will use interrupt-driven architecture, low-power sleep strategies, watchdog management, and efficient JSON packaging to meet the 10-second publish target and ≤150 µA standby requirement. You’ll receive a fully compilable E2 Studio project, documentation for build/fuse/update steps, and one week of post-handover support for bench or road testing adjustments.

As an Embedded Systems and Electrical & Electronics Engineer with over 5 years of experience, plus my proficiency in software engineering and PCB design, I believe I am perfectly aligned for your project. My extensive knowledge of the RL78 toolchain, Renesas peripheral libraries and low-power embedded networking will help me hit the ground running. I have a solid background in developing clean, well-documented C code such as you require for your vehicle-tracking PCB project. Having designed/embedded solutions using various microcontroller platforms will ensure I provide reliable solutions to your GPS receiver and cellular modem integration over UART/SPI. My electrical principles understanding further strengthens my power-aware design approach including sleep modes, clock gating and watchdog strategy required to conserve battery life. Another aspect where I can shine is in delivering projects on time whilst maintaining the highest standards of efficiency. This has been evident in my multi-disciplinary approach like combining AI with software engineering to yield smart and efficient solutions. From acquiring a GPS fix to publishing JSON payload within 10 seconds to ensuring SD card holds identical coordinate/time stamps for every published sample, rest assured you'll receive an end product that ticks all your acceptance criteria boxes. Look no further for this project; let's build something great together!
