THE EZ-CPU CONTROL SYSTEM
Welcome to the EZ-CPU page. The EZ-CPU has been specially developed to teach low level language programming to A-level and degree students. It emulates the 8088 16 bit processor and the very powerful Z80 8 bit processor. There are free teaching resources available and more being developed all the time.

8-bit CONTROLLER FOR STUDENTS - DESIGNED BY TEACHERS FOR TEACHERS!
|
 |
FEATURES:
|
| Z80 & 8088 instruction sets |
| 8 bit Input & Output ports with 4mm sockets |
| 16x2 LCD Display |
| 96 byte user RAM, 256 byte non-volatile program memory |
| Selectable CPU speed,1KHz-100KHz |
| 7-10v DC supply |
| 2K EEPROM memory for loading and saving up to 8 pages of programs. |
| Serial PC connection |
| STEP mode for displaying registers and debugging routines. |
|
|
The EZCPU is a fully functional 8-bit emulator designed to teach A-level and University students to write instruction code for 8088 (32 instruction) and Z80 (500 instruction) processors.
The EZCPU system has been designed by teachers, for teachers, to assist in delivery of AQA & OCR Electronics and other syllabus. Tried and tested with students with outstanding success, pupils quickly learn to write control programs and routines.
|
SUPPORT
Purchase of any EDUTEK product qualifies you for free support on-line and advice concerning delivery of the syllabus and use of products purchased. Also free advice on circuit design and fault finding for teachers and students.
|
The EZ-CPU enables control over a variety of applications. Connection to input and output buses uses 4mm sockets and 10 way headers for the expansion modules, which allow for almost any control application and satisfy the requirements of the OCR CONTROL SYLLABUS
There are a range of free worksheets, example flowcharts and notes for teachers and students. |
|
|
|

|
|
PROJECTS & APPLICATIONS
A wide range of control projects and applications can be made by adding expansion modules. For example using the 8-bit DAC module, students can create digital waveforms and sound generators.
There are some programs and examples covering most aspects of the module available on the EZ-CPU resource page.
|
 |
The EZ-CPU has a serial connection allowing students to upload their work to a PC for printing and assessment. Download exemplar routines into boards for demonstartions and set tasks.
 Software is free!!
