以太网和CAN总线应用广泛,但由于其通信协议不同,两种总线器件间无法进行数据通信,因此,设计了基于CP2200与C8051F040的以太网总线与CAN总线接口转换电路,并给出部分相关硬件电路与软件设计...
介绍了当前普通标记机控制系统现状及其存在缺点,给出气动标记机及相频修正PWM模式的工作原理。采用ATmega16单片机和USB转换RS232接口器件CH341T实现驱动控制系统与PC的实时通讯,标记控...
针对材料试验机等设备中要求测量或控制材料拉伸或压缩的位移,一般采用光电轴角编码器检测位置信号,输出正交编码脉冲信号。若采用其他方法检测位置信号,必然导致电路设计复杂,可靠性降低。因此,提出一种基于LS...
汇编器在微处理器的验证和应用中举足轻重,如何设计通用的汇编器一直是研究的热点之一。本文提出了一种开放式的汇编器系统设计思想,在汇编语言与机器语言间插入中间代码CMDL(code mapping des...
