AI overview

Firmware is low-level software that's permanently stored in a device's memory (like EEPROM or Flash memory) and controls how the hardware actually works. It matters because devices need this built-in software to function, and it can usually be updated through standard communication methods like SPI protocols.

In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction services to higher-level software such as an operating system.
