The Broadcom I2C Controller Driver for Windows is a software driver that allows your Windows operating system to properly communicate with I2C (Inter-Integrated Circuit) devices on Broadcom hardware. I2C is a communication protocol used by various sensors, displays, memory chips, and other peripherals that are commonly used in embedded systems and computing devices.
When you have a Broadcom-based chipset or motherboard, the I2C Controller Driver helps the operating system recognize and manage communication with these connected I2C devices. Without the driver, the system might not detect the devices connected via the I2C bus, and you might face issues such as malfunctioning hardware or error messages.
