A number of files/programs that belong to te article about ZEP.
The purpose of this article is to get a publication in a peer reviewed article. We Hope that this creates extra some extra momentum for Zep. There are many tools one can use to create psychological/psycholinguistic experiments. Zep is special to those, because it is a relatively simple language to master and does the very difficult stuff under the hood. All files in this repository Fall under the GPL-2.0 open source software licence, for details see the LICENSE file at the root directory.
The articile aims to present Zep major version 2.0. Hence, the scripts in this repository should be run with zep-2.x .
The build tree has a number of directories with different purposes.
This directory contains some helper files to create electronic schematics of the experiment setup. This presents an overview of how the different electronic connections should be made.
This directory contains the firmware used to do the measuring with a teensy device. More information about Teensy devices can be found at: https://www.pjrc.com/teensy/ . In short a teensy device is a ARM-Cortex M4 development board. This allows us to time changes on electronic sensors in a realtime fashion.
This directory contains small utilities used internally to help ourselves.
This folder contains 2 scripts in these scripts these script generate the data presented in the article. These scripts use the zep teensy plugin to communicate with the teensy device.
When Zep connects with a teensy device, the device resets its time to 0, every x µs the timestamp is increased. Currently x = 10µs. Zep only gets events about electronic sensor events and cannot adjust the timing. Each event has a teensy timestamp, a pin value and the logical readout value of such pin. This makes the teensy an objective time measure tool.
