The older computers also ran around 1 to 4 megahertz (MHz), whereas the Raspberry Pi runs at 700 MHz. And the Raspberry Pi is far from the average home PC. Today, boxes with 2 GB RAM and 2 GHz processor speed are common.
ASIO is a standardized way of describing the communication between audio software and a piece of audio hardware. It enables audio hardware manufacturers to write optimized drivers for their hardware that bypass the potentially high latency operating system mechanism for supporting audio hardware.
Write a driver for a general-purpose I/O (GPIO) controller or for a peripheral device that connects to GPIO pins on that controller. A GPIO controller driver handles I/O requests to read or write to groups of GPIO pins. Typically, these pins are used to communicate with peripheral devices that are attached to computer motherboards or that are embedded in mobile devices, such as smart phones.
