The need to provide custom controls for complex software packages has been satisfied in many ways, the most usual of which is to have a configurable keypad. It’s a challenge [Meir Michanie] has taken up in a slightly different way, by creating a custom touch-screen macro pad. Unlike the buttons, this allows entirely custom layouts with different shaped keys in any configuration.
At its heart is a versatile ESP32 touch screen development board of the type that can be found easily among the pages of your favorite online electronics mart. The Arduino IDE has been used to program the device, and configuration is as simple of providing it with a PNG of the desired layout, and a CSV file to define the buttons. The whole then connects via BLE where it’s presented to the host computer as a keyboard. The result is one of the coolest macro pads we’ve ever seen, with a limitless number of options.
With such a neat idea it’s perhaps no surprise among the numbers of macro pads that have made it to these pages there might be another take on the same idea.
