1- Display & Animation: Used LVGL to draw eyes (globe, iris, pupil, eyelids) and created an initial animation engine, (final state of each animation with intermediate states considering eye physics: saccades and blinks ..)

2- Connectivity:

- Provisioning: Implemented BLE pairing.

- UI: The pairing PIN is dynamically displayed on both screens (split into two parts).

- Wifi: Automatic connection once paired.

3- Audio:

- Input (microphone): Configured I2S in reception. Calculated RMS (sound level) and VAD (Voice Activity Detection)

- Output (speaker): Configured I2S in transmission, integrated a .wav file (played in chunks to allow volume adjustment),

- Ensured in the algorithm that the speaker emits audio (played file) whenever voice activity is detected.

Development of a microcontroller inventory management system:

• Integration of an NFC module for card identification and tracking.

• Implementation of SubGHz connectivity for data transmission to a remote server.

• Automatic update of the centralized database via a server-side script.

• Creation of a graphical interface for data exchange with the system.

Development of an I2C driver for ADXL345 with interrupts:

- Deployment of an embedded Linux system under QEMU (ARM Cortex-A9).

- Design of an I2C driver for an accelerometer, user interface via the misc framework, data acquisition via interrupts with Threaded IRQ and software FIFO.
