I developed embedded firmware and hardware for RFID locks in a hotel within six months. The project included creating a card reader device for guest cards and a door lock embedded board to read the cards and execute necessary actions. Customer requirements were captured, and a system requirement document was released.

The development included R&D, POC, and final phases. The R&D involved finding appropriate hardware and software support, the POC phase involved developing 1st boards and basic operational software, and the final phase involved the production of hardware and software for all functionality and specification requirements.

Deliverables included five sets of reception and door lock hardware, an interface document, sample code for the reception card reader, PCB schematics, Gerber files, source code, and binaries.

I developed the architecture and firmware for the basic and final firmware for PN7462 on MCUXpresso IDE. PCB Schematics/Gerbers were developed using Altium Designer Suite of CAD Tools.

While moving from the basic boards to the final miniaturized boards, I had the challenge of tuning the antennas using Vector Network Analyzer (VNA) to get the Smith charts to establish impedance matching for the antenna.
