Drivers for free‐form modular displays

Abstract

When displays of different sizes and shapes are required, a modular display system seems to be a good solution. Many systems offer only a limited freedom of shapes. The display can be scaled, but no irregular shapes can be created. If those shapes can be created, the configuration is often manual. A more intelligent modular system allows all shapes to be created and configures automatically. This paper presents two drivers that can be used in such a modular system. The first driver ensures that the data finds its way to every module and is displayed, even if there are some “holes” in the display due to missing modules. The second driver adds some extra functionality. The precise display configuration can be detected, and in the graphical user interface (used for controlling the display) the user sees an updated view of the display configuration when modules are added or removed. Both drivers have been proven successful and results are presented in this paper

“…However, the microcontroller can only receive one address at the time, so the sending of the addresses has to happen in a controlled way. This is done using the shout routine [16]. With the bypasses still inactive, a module tries to send (shout) its address by first sending a shout request to its parent.…”
