@sebromero sebromero commented Dec 18, 2025

This pull request introduces a new NiclaSenseEnvSerial helper class to simplify parsing and accessing sensor data from the Nicla Sense Env board over UART, and refactors the UARTRead example to use this new class. The changes remove the previous manual CSV parsing logic and replace it with a more maintainable and reusable approach, while also improving code readability and API consistency.
