Hi there, I’ve carefully read your project description and I fully understand the scope: delivering production-ready firmware for a dual-MCU grid-tied inverter (STM32F103 + TMS320F28035), including MPPT, PLL synchronization, anti-islanding protection, and robust communication between control layers. This fits my skillset very well. With my background in mechatronics and power electronics, I have strong experience in embedded control systems, real-time firmware, ADC/PWM optimization, and control-loop implementation for high-performance systems. I’m comfortable working with STM32 and DSP-based architectures, including coordination between MCUs for deterministic and stable operation. I can implement clean, well-structured firmware covering fast sampling, synchronized PWM generation, MPPT algorithms, PLL for grid locking, and reliable anti-islanding detection. I will also ensure robust communication between the STM32 and TMS320, along with clear documentation, build instructions, and validation results aligned with your acceptance criteria. Given my experience, I’m confident I can deliver this efficiently and professionally. Just send me a message and we can get started right away. Best regards, Samuel Tshibangu

Drawing on my extensive experience in industrial automation and process control, I believe I am the ideal fit for your Solar Inverter project. My skills in C programming, electronic design, and embedded systems align perfectly with your needs. In particular, my familiarity with power electronics projects and dual-MCU development will ensure a reliable and robust firmware for your grid-tied solar inverter. To detail further, I have successfully executed projects using Siemens TIA Portal, Simatic Manager, WinCC SCADA, and E Plan P8 V2.6., which involved system software writing, monitoring and control systems development, reporting and point-to-point testing - all of which are directly relevant to your project's requirements of precise grid synchronisation and remote monitoring. In terms of power electronics projects specifically, I have worked with Delta PLCs, ABB PLCs and SCADA systems, and SIEMENS PH & INFORMATION SERVER program - all experiences that closely mirror the demands of your grid-tied solar inverter. Ultimately, my track record speaks for itself; my solutions are innovative and efficient. It would be a privilege to bring this expertise to bear on advancing your solar energy initiative.

I have developed a DC-DC converter with closed-loop control and real-time monitoring using STM32. I have also worked on multi-controller communication setups for synchronized control. For your inverter, I will design the firmware in a structured way where STM32 handles fast data acquisition (ADC), communication, and system monitoring, while the TMS320 handles real-time control algorithms like MPPT, PLL, and grid synchronization. I will ensure both controllers communicate reliably and the system responds quickly to faults like islanding. The focus will be on stable synchronization, efficient power tracking, and safe operation under all conditions. Deliverables will include: 1. Fully commented C code for both MCUs 2. Ready-to-flash binaries 3. Build instructions 4. Test results for MPPT performance and protection response. I also have a complete electronics lab setup, so I can test and verify the firmware behavior to ensure reliable performance before final delivery.

I have hands-on STM32 firmware experience in C — including ADC fast sampling, high-resolution PWM generation, UART bidirectional communication, and real-time control loops. A relevant deployed project: a cold storage monitoring system with STM32-class MCU, multi-channel sensor acquisition, real-time data processing, and remote UART monitoring — the same fundamentals your power board requires. For this project I can handle the STM32F103 side fully: ADC configuration for voltage/current sampling, PWM for the full-bridge switching stage, UART framing for the remote monitoring link, and handshaking protocol with the TMS320. For the TMS320F28035 DSP layer — MPPT, PLL, anti-islanding, and grid-synchronised control algorithms — this is specialised power electronics DSP territory. I can contribute to the integration and communications layer but want to be transparent: do you have existing TMS320 firmware or reference code I can build from, or is this a full ground-up implementation? Delivery of the STM32 firmware layer within 2 days of receiving your schematic and peripheral map. What is the current state of the TMS320 side — existing code, reference design, or scratch?

Hi, This is a serious embedded power-electronics project, and I understand you need much more than basic MCU programming — you need a stable dual-controller firmware stack across **STM32F103 + TMS320F28035** that is ready for real inverter operation. I can work from your existing hardware design and focus on the full control path: fast sampling, PWM/UART integration, MPPT, PLL, anti-islanding, MCU handshaking, remote monitoring, and clear build/integration support for your hardware team. My focus will be clean, well-commented firmware, practical validation, and a production-minded approach so the system is stable, testable, and easier to bring up on hardware. I’d be glad to discuss the current board status and firmware split first, then move in a structured way toward the final deliverables. Best regards. Ankit.

Hi there, We see a strong fit for this dual-MCU inverter firmware scope and would approach it with a structured, test-led delivery plan. Our focus would be on clean partitioning between the STM32F103 and TMS320F28035, robust peripheral setup, deterministic control timing, and practical validation against the stated acceptance criteria. To reduce risk, we would first confirm the hardware interfaces, control responsibilities, and the communication handshake between boards before implementing the control stack. We can then move into firmware implementation, integration, and a verification pass that aligns with your build tools and handover needs. If helpful, we can also share a short relevant example of embedded control architecture in our response. Best Regards, 8veer
