PICO C Project with I2C Control

I'm in need of a skilled professional to assist in controlling multiple I/O devices via the I2C interface in my PICO C project. The schematic capture has been completed, but might require some adjustments tied to project milestones. After this phase, I'll be handling the PCB layout and procuring the first test board.

Key Responsibilities:
- Adjust schematic capture as necessary
- Write PICO C code for controlling sensors and actuators
- Include RaspPi5 test code to verify I2C commands
- Focus on critical functionalities such as control commands, error handling and I2C two-way communications

Experience with I2C communication is essential, specifically with a single master and multiple slaves configuration. Proficiency in PCB design and familiarity with test procedures for I2C communication is highly desirable. The project is currently at version 1.4, with a completed write-up.
