Servo Motor Firmware Development
Budget: ₹12,500 – ₹37,500 INR
My project centres on a microcontroller dedicated to precise servo-motor control. The basic hardware is already on the bench; what’s missing is reliable, well-structured firmware that can translate high-level movement commands into clean, jitter-free PWM signals.
Here’s the flow I have in mind:
• Initialise the microcontroller peripherals (timers, ADC if feedback is used, and a simple comms interface such as UART, I²C, or SPI).
• Generate adjustable-frequency PWM with fine-grained duty-cycle control suitable for standard hobby-grade or industrial servos.
• Optionally close the loop with a lightweight PID routine once position feedback is wired in.
• Implement basic safety features—time-outs, brown-out detection, and a failsafe position.
• Expose a straightforward command set so that a higher-level board or PC can request position, speed, or torque changes.
Deliverables that mark the job complete:
1. Fully commented source code (C, C++ or embedded-Rust—whatever you prefer), ready to compile with the vendor toolchain.
2. A brief README covering pin assignments, build steps, and an example command sequence.
3. A short video or logic-analyser screenshot that proves repeatable, stable servo motion across the full travel range.
If you have experience squeezing every microsecond out of timer interrupts and know your way around debouncing and EMI considerations, this will be quick work. Let me know which MCU families you’re most comfortable with and any libraries or drivers you plan to bring in, and we can lock down the specifics.
