This week, I focused on refining our NFC scanner setup by switching from I2C to SPI, which better supports multiple scanners on one pad and eliminates the need to boost the input logic to 5V. I soldered additional NFC scanners and worked on connecting multiple scanners to a single ESP32. Additionally, I helped Sarah set up all the hardware components so she could integrate them with the backend of our app.
While progress was made, ensuring all scanners work seamlessly with one ESP32 remains a challenge. Connecting multiple scanners introduced new debugging considerations, which I will continue to address. Despite this challenge, we are still on track with our goals.
Looking ahead, I plan to finalize the scanner setup so all units function reliably with one ESP32. I will also focus on planning a more streamlined circuit design and soldering it onto our flat breadboard. Additionally, I aim to conduct initial testing to identify and resolve any issues early in the development process. Ensuring stability across all hardware components will be key as we move forward.
