Vintage data-transfer tech gets upgrade after 35 years
Tech artifacts like old Mac computers are finding their way to museums, but some never-say-die technologies continue to serve requirements important to computing.
Inside wearables, smart devices, robots, and computers like Raspberry Pi are communications buses called I2C (Inter Integrated Circuits), which date back to 1982, and SPI (Serial Peripheral Interface), which was born in 1979.
Those buses have driven short-range communication between circuits and microcontrollers for decades. They now serve as key interfaces for sensor-related communication on smart devices, wearables, and computers.
