The limitation of the SmartDrive-i2c-P.i.D. driver in simultaneously controlling both motors at maximum speed suggests a critical need for a more robust solution, particularly in the realm of CAN Bus communications. Leveraging advanced motor control algorithms integrated with CAN Bus will enable synchronized operation of both motors, ensuring optimal performance. I propose developing a custom H-Bridge controller tailored to your specifications, focusing on efficiency and reliability. Initial deliverables can be ready in 10 days. Can we hop on a 10-minute call this week?

Hi, We are available to take this on and build a high-performance motor driver board that resolves the simultaneous motor drive issues found in your previous I2C P.I.D. setup. Since you are using Teensy 4.1, we will integrate a dedicated CAN-FD transceiver and an MCU like the ESP32-S3 or an STM32 to handle the local PID loop and encoder processing because offloading these real-time tasks from the CAN bus is much cleaner. We will include the necessary pull-up/pull-down resistors directly in the PCB design to ensure your incremental encoders read perfectly without extra boards and we will select a robust H-bridge stage capable of handling the 17A peaks from your wiper motors. Our team recently fixed a similar system for a logistics firm that needed precise motor control and used the same logic to hook into real-time sensor data and built a robust firmware architecture that validated inputs before execution. We corrected their PCB layouts for JLCPCB manufacturing to ensure the components were available and the routing was optimized for high-current paths. Our fix stopped their data loss and made the whole balancing process way faster for their hardware. We are eager to discuss the project further and can provide the full BOM and Gerber files for Sao Paulo delivery. Reach out to initiate a conversation! Best regards, Quantum Code Solutions

Dear Client, I have read your requirements carefully, and I understand you need a replacement for the SmartDrive-i2c-P.i.D. driver because it cannot reliably drive both motors at maximum speed at the same time. You need a more robust controller solution built around proper motor control, embedded logic, and CAN/CAN-FD communication for your robot platform. I have worked on similar embedded and robotics projects involving motor drivers, microcontrollers, control logic, communication buses, and hardware-focused debugging. The best approach is to review the current failure behavior, confirm the electrical/control limitations of the old driver, and then build a cleaner controller design that can handle both motors reliably under full-load conditions. I can help with the embedded control side, motor-driving logic, CAN-FD communication structure, and practical design decisions needed to make the new controller stable and usable. I’m new on Freelancer, but I bring rich experience and would love for this project to become my first approved project on the platform. That is why I’m fully committed to delivering quality work, clear communication, and a smooth result from start to finish. I would be genuinely happy to work with you on this project.
