Linux users who require a rotary telephone dial as a peripheral for their computers can utilise a driver created by Stefan Wiehler, which presents the dial as though it were a number pad.
The driver is aimed at systems-on-chip with ample GPIO access, and once configured it can be used for interfacing with a dial.
While this could be a fun project for some, there are simpler ways to use a dial phone, such as following a guide that uses an Arduino and employs a similar concept to Wiehler’s driver.
Ultimately, it may be a little too niche for mainstream inclusion, but it could find use in old-school dial IP phones using Linux-capable dev boards.
