WebA hardware interrupt is an electronic alerting signal sent to the processor from an external device, like a disk controller or an external peripheral. For example, when we press a key on the keyboard or move the mouse, they trigger hardware interrupts which cause the processor to read the keystroke or mouse position. Software Interrupt WebSep 2, 2014 · And the peripheral driver layer. On top of the HAL sits the peripheral driver layer. Many developers are familiar with this layer, as it appears in slightly different variants in most applications. The driver layer fully abstracts the hardware into generic terms. For instance, an I2C driver has an API defined in terms of I2C-bus operations.

WebI/O peripherals -- The input and output devices are the interface for the processor to the outside world. The input ports receive information and send it to the processor in the form of binary data. The processor receives that data and sends the necessary instructions to output devices that execute tasks external to the microcontroller.
