The I2C class provides a simple interface to the I2C bus. It is a wrapper around the esp-idf I2C driver.
+A helper I2cMenu is also provided which can be used to interactively test +I2C buses - scanning the bus, probing devices, reading and writing to devices.
A CLI menu for interacting with an I2c bus.
+This class provides a CLI menu for interacting with an I2c bus. It provides options for setting the log verbosity, scanning the bus for devices, probing for a device at a specific address, reading from a device, and writing to a device.
