这个是用DS18B20做的一个作品,所用语言是汇编语言程序.-DS18B20 to do this is to use a work, the language used is the assembly language program.

介绍asm的工具书，里面有一部分基础的汇编只是，还有对tasm使用的介绍-Asm introduction of the tool, which has only part of the basis of the compilation, but also introduce the use of TASM

详细说明了字符串的用法，以及对示例代码的详细说明

LM358 内部包括有两个独立的、高增益、内部频率补偿的双运算放大器，适 合于电源电压范围很宽的单电源使用，也适用于双电源工作模式，在推荐的工 作条件下，电源电流与电源电压无关。它的使用范围包括传感放大器、直流增 益模块和其他所有可用单电源供电的使用运算放大器的场合。 LM358 的封装形式有塑封8引线双列直插式和贴片式。-LM358-house, including two independent, high gain, internal frequency compensation of the dual op amp suitable for a wide range of supply voltage single-supply use, also applies to dual power mode, the recommended working conditions, supply current and supply voltage has nothing to do. It covers the use of sensing amplifiers, DC gain blocks and all other available the use of single power supply operational amplifier occasions. LM358 package has the form of 8-lead plastic DIP and SMD-type.

在多数情况下,集成电路芯片的管脚不会全部被使用。例如74ABT16244系列器件最多可以使用16路I/O管脚,但实际上通常不会全部使用,这样就会存在悬空端子。所有数字逻辑器件的无用端子必须连接到一个高电平或低电平,以防止电流漂移（具有总线保持功能的器件无需处理不用输入管脚）。究竟上拉还是下拉由实际器件在何种方式下功耗最低确定。-in most cases, the IC chips will not pin all been used. For example, 74 ABT16244 series device can use up to 16 Road I/O pins. but usually not all use, so there will always be vacant terminal. All digital logic device useless terminals to be connected to a serial or low-level. to prevent the current drift (with the bus maintain functional devices need not deal with the importation of pins). What to draw from the drop-down or what the actual device under way to determine the minimum power consumption.
