一、电路概述 BL0508是一块远红外线遥控发送大规模集成电路,电路内部的逻辑和编码格式采用日本90年代的设计思想,它具有32个单键和3个双键操作指令,通过选择位,可得到64+6个功能指令。此发送码由引导脉冲、16位用户码、16位数据码这三部分组成。主机使用微处理器解码,由于发送码中采用了16位用户码,比一般的常规发送电路增加了字长和验证格式,所以具有较强的抗干扰能力,误码
First, the circuit overview BL0508 is a far-infrared remote control to send large-scale integrated circuits, the circuit logic and coding format Japanese 90’s design, it has 32 single-key and three double-key operation instruction, through the choice of bit Get 64 + 6 function instructions. The transmission code by the pilot pulse, 16-bit user code, 16-bit data code of these three parts. The host computer uses the microprocessor to decode. Since the sending code uses 16-bit user code, which increases the word length and verification format than the conventional sending circuit, it has strong anti-interference ability and error code
