DESIGNING OF MICROCONTROLLER 8051 BASED LEARNING MEDIA OF CONTROL BY USING THE MCU 8051 IDE AND C PROGRAMMING LANGUAGE WITH A C-COMPILER OF SDCC-SMALL DEVICE C COMPILER TO SUPPORT THE IMPLEMENTATION OF ACTIVE LEARNING IN HIGHER EDUCATION-ALFHE (ACTIVE LEARNING FOR HIGHER EDUCATION)

摘要

On this occasion the author developed Microcontroller 8051 based Active Learning Media of control using 8051 microcontroller simulator MCU 8051 IDE on Windows 7 (MCU 8051 IDE can basically run on various operating systems) to support the implementation of active learning in higher education. Instructional media developed in the form of a controlling simulation program in C language with SDCC compiler-Small Device C Compiler. The developed simulator will mimic a control system consist of an input switch connected to PO.O that imitate an input from a sensor and an alarm as an output in the form of a Virtual Common Anode Seven Segment Display that will display a character "L" or "H" in accordance with the input from the sensor; this virtual output device connected with P1 of 8051. Based on the author class observation, this simulator has been successfully enhanced the participation of the students in the learning process, allowing the author to apply his learning strategy properly and successfully overcome the lack of funds to meet the need of spending for equipments. The simulation program has also been successful in reducing errors in building a real devices (reducing the costs of production).
