Design documentation for C64 and VIC-20 touch screen controller
In this project, Nextion HMI 2.4-inch touch display is used as a controller for Commodore 64 and VIC-20 computers. The touch screen emulates paddle controllers similarly as the well-known KoalaPad.
The technical details of the project have been published in the Finnish computer culture magazine Skrolli in issue 2018.4, and will be published later in this repository.

Touch display for VIC-20
Please note: The design could have more potentiometers in series. The C64/VIC motherboards specify 470kohm potentiometer for paddles, but the above design uses 200k. The closer to 470k the total resistance is, the more accurate the device is.
