@AITSoft

Hello, I understand you need firmware for a PIC16F84 microcontroller to control a motorized door with open/close and lock/unlock functions via buttons or switches. Alternatively, you want an exact copy of your current locked chip, which requires careful analysis and reverse engineering as the original is unsupported. I can handle both writing new firmware or duplicating the existing code by studying the chip’s behavior and replicating its functions. I'll ensure smooth, reliable motor control and secure activation methods as you described. What are the exact button or switch types and wiring you use? Do you have the schematics or hardware setup details for the door and motor? Is there any timing or security protocol needed during operation? Can you provide the locked chip for analysis, or is it embedded in your system? Are there any specific fail-safe features you want included? What are the exact button or switch types and wiring configurations used for controlling the door? Best regards,

@TheElitePro

Hi, I have implemented several industrial and home automation projects using Microchip PIC16F and PIC18F micro controllers. 1. I understands the technical requirement in detail and I have developed and delivered turn key projects. Many freelancers has just worked on either hardware or a specific controller firmware. 2. I am preferred freelancer and I have earned this badge in less than two years of time. I have worked in the industry for more than 22 years and now working as freelancer while most of the freelancers doesn't have industry expertise. 3. I have developed applications which are in mass production and installed in several countries. This gives me an edge in development as I think about functional as well as performance and usability requirements. 4. My extensive skillset covers from architecture design to firmware programming, hardware development as well as software programming. I have done motor control programming for industrial and residential water softeners. 5. My work spanned across various industries, including industry 4.0, video surveillance systems, energy meter solutions. I’m used to thinking beyond just the firmware but also consider how it may integrate with larger systems or future developments. I understand that you have an existing chip and it's locked so flash can't be read, so I will understand all the functionality and develop a new production ready code. Please let me know your suitable time for a detailed discussion. Regards, Vishal

@Ryan15222

Hi, I can help you develop reliable firmware for your PIC16F84-based motorized door controller, but I want to be clear upfront: I cannot assist with copying or extracting code from a locked chip. What I can do is analyze the system behavior and recreate equivalent (or improved) firmware tailored to your hardware. I have solid experience with PIC microcontrollers and embedded control systems, including motor actuation, limit handling, and safe state management. Proposed solution: I will design clean, deterministic firmware to handle: • Door open / close control (motor direction, timing, interlocks) • Lock / unlock mechanism (separate actuator or sequence control) • Inputs from buttons / switches / key interface with proper debouncing • State machine logic (OPEN, CLOSED, MOVING, LOCKED, ERROR) • Safety features: limit switch handling, timeout protection, conflict prevention (no simultaneous commands) Optional enhancements (if applicable): • Soft start/stop behavior (if hardware allows) • Fault detection (jam, timeout) • Status outputs (LED or signal feedback) Deliverables: • Fully documented PIC16F84 firmware (ASM or C, depending on toolchain) • Clear pin mapping and logic description • Timing and control flow documentation • Support during testing on your hardware If you can share: • Current wiring / pinout • Motor driver type (relay, H-bridge, etc.) • Limit switches or sensors used • Expected behavior sequence

@dariol63

Hello, Thank you for the opportunity to submit this bid for your project. I have carefully reviewed the door controller scope for a PIC16F84-based firmware that can open/close and lock/unlock the door, and I’m confident I can deliver a robust, reliable solution or accurately clone your existing locked chip if needed. As a past embedded-systems specialist, I’ve solved similar motor-control and state-machine challenges in tight timing windows, ensuring safe and deterministic operation. My plan: ✓ Analyze preferred I/O mapping and timing for open/close and lock/unlock sequences. ✓ Implement a clean, safe state machine in C with debounced inputs, watchdog protection, and fail-safe states. ✓ Integrate motor control routines (PWM or direct drive as required) and a button/switch plus optional keypad input. ✓ Validate on bench hardware with edge-case testing and provide compact ROM/firmware suitable for PIC16F84. Do you have a detailed schematic, motor specifications, and timing requirements (response/relock delays) to ensure the firmware meets your exact door-control behavior? Please I would love to discuss this project further and answer any questions you may have. Best regards, Dario

@generosoiii

Hi there, It sounds like you're dealing with a locked PIC16F84 that controls a motorized door system, and the inability to copy or modify it is blocking your progress. I've spent the last 5 years building and troubleshooting firmware for PIC microcontrollers, including door controllers and motor/lock systems just like this. If writing new firmware, I'll map the I/O pins, implement debounced button/switch input handling, design a reliable open/close and lock/unlock sequence, and integrate any required safety or timing logic for the motor. If you prefer cloning, I can analyze the locked chip, extract behavior through signal tracing, and recreate equivalent firmware so your system operates exactly as the original. Before I proceed, quick question: Can you confirm whether you want a full firmware rewrite or an exact behavioral replication of the existing PIC16F84 chip? Best regards, Generoso III
