This page describes some pieces of computer software prepared to be used along with the MIXI applications, which can be requested using this request form. Other pieces of software are described by this page.

MIXI Test sheet generator program

This program was designed to edit, to generate and to print test sheets for the MIXI Quiz application. The program lets the user choose to edit the list of questions or to convert a text file containing the list of questions conforming to a defined format. The teacher can steer the generation of the test sheets by parameterizing the generation process. In addition to the examination of the student (test mode), the program can be used by the student to practice (practice mode). A time limit that applies to each question can also be set. Before generating the questions, the teacher enters the generation code that influences the order of questions and answers on the test sheets. The program is able to prepare 256 versions of the same question list with the same conditions. The program enables the user to optionally preprocess the generated test sheet with an editor, and to print the test sheets.

The first version of this program was developed in 1995, and it ran under DOS. In 1998, we prepared the new version that runs under Windows. The new version also supports 255 characters long questions and answers, in the previous version, these were limited to 160 characters. In order to make the program easy and efficient to use, we added the option of entering the number of copies to the test sheet generation function. The first version ensured only the mixing of the questions for one code, the position of the correct answer remained the same (e.g. 1st question - answer is C, 2nd question - answer is E, etc). The new version enables the user to enter the required number of copies, and then to preview the printed images. The new version assigns a different mix code to each copy. MIXI users can request the version of the program that contains even a question database.

MIXIDraw function generator program

The MIXIDraw function generator program belongs to the MIXI application Programmable D/A converter. The program enables the user to define a signal, and to download it from the computer through the parallel port and the transfer cable to the application (the cable is an accessory to the application).

The first version of the program was developed in 1996, and ran under DOS. It enabled the user to use the mouse to draw the signal. This method allows us to quickly make a signal with given characteristics, without knowing its exact formula. The program allowed the user to download the signal to the application, and to choose between single or cyclic download.

In 2001, we developed the new, Windows-based version of the MIXIDraw program. One of its new features is the formula-editor that enables the user to enter a formula if he knows it, using any polynomial or periodic formula that conforms a certain pattern. Both methods allow the user to use the so called background signal that does not influence the editing process of the program but it can serve as a visual reference for the user during the editing process.

PAL/GAL circuit design program

The PAL/GAL circuit design program belongs to the MIXI PAL/GAL application, that is, the program is necessary for the user to program the application.

The application enables the user to realize a combination circuit with at most 6 variables and 7 minterms. The program allows the user to devise logical functions either graphically or with a formula, and to download them to the application.
