Tillypad XL can use different devices: fiscal registers, customer displays, pool control device, paging stations, and many others. These devices can be real, e.g. a printer, and virtual, e.g. a portable storage replication assistant. Device drivers are used to control all these devices. Device driver is a software module with settings configured so that it can control a particular device. For the sake of simplicity, this description uses the word devices to describe device drivers.

Software module parameters (parameters, format types, configurable value types, etc.) merge with parameters specified for a device. Parameters specified for a device cover up (have priority over) similar software module parameters.

To manage devices used in Tillypad XL , use the Devices directory.

The Devices directory has a list of devices and device loaders. This list shows how the devices are connected. A device can be connected to another device or to a device loader. To connect one device to another, you need to specify the parent device software module in the specification of the child device connecting software modules.

Device loader is a software that is set up or started as an application or a tool (in manual or automatic mode) on computers where the device drivers need to be loaded.
