Design of an One-Chip Controller for an Electronic Dispenser

The electronic dispenser is composed of electronic part and mechanical part. Electronic part is consisted of input keypad, micro-controller, display module, and pump module. In this paper we designed micro-controller for electronic part. The micro-controller controls display module and pump module. The display module is composed by LCD device, and the pump module is composed by motor device. The micro-controller for an electronic dispenser is designed by VHDL. We used WX12864APl for the LCD device and SPS20 for the stepping motor. Also, the micro-controller is designed by Altera Quartus tool and verified with Agent 2000 Design-kit using APEX20K Device. In this paper, we present possibility to adopt of biotechnology field through designing of one-chip controller for an electronic dispenser.
