| Abstract: | A scheme about instrumental man-computer interface is proposed. Its structure of bus and communication protocol are presented. The display region is partitioned into four section: running mode, setting parameter, running parameter and prompt. A 10 to 4 encoder is used as interface of key to MCU. The optimization design is accomplished, which enables to reduce the occupying of MCU pin, reduce the occupying of MCU time and simplize the procedure design. |
