us ponents from the library selection need drawing diagram and set ponent, the corresponding element parameter values . Keilc Keil Vision 2 is about the 8051 series MCU Keil pany of development tools can be used to pile C source code, assemblers source program, connection and relocation target files and libraries, gen built: documents, debugging purposes procedure, etc, it is a kind of integration of document management pile environment. It integrates document editing processing, pile connection, project management, window, tools cited and software copy true debugging and other functions, is pretty powerful development tool. In keil inside pile, the procedures required missioning . alignment (1) detection TCP/IP. (2) duplicate the Proteus installation directory vdm51. Who folder keilc/C51 / DLL to bin directory. (3) modify the installation directory Keil tools. TDRV4 = BIN, add the DLL. VDM51. \ (4) in the schematic drawing Proteus, in Debug menu, select Use Remote Debug hand . (5) in open in a project Keil, rightclick Target1, choose for Target 39。t because when heating and burned, but can39。 C, in 10 ~ + 85 176。 two 16 timer and MCS 51 patible Typical products have AD590 AD592, TMP17, LM135, integrated temperature controller. Analog integrated temperature controller mainly include temperature control switch, programmable temperature controller, a typical product have LM56, AD22105 and MAX6509. Some increase strength type integrated temperature controller (for example TC652/653) also contains the A/D converter and cure good sequence, this process with the intelligent temperature sensor some similarities. But it is not its system, work by micro processing device control, this is the main difference between. Intelligent temperature sensor. intelligent temperature sensor (also called digital temperature degrees sensor) is in the mid 1990s launch. It is microelectronics technology, puter technology and the dynamic testing technology (ATE) crystallization. 第 2 頁 Intelligent temperature sensor internal contain temperature sensor, A/D converter, signal processor, memory (or registers) and interface circuit. Some products still take multiplexer, central control system device (CPU), random access memory (RAM) and read only memory (ROM). Intelligent temperature sensor is characteristic of temperature data and relevant can output the temperature control of the quantity, adaptation various micro controller (MCU)。 level 3 program memory lock s sake. RST: reset input. When oscillator reset device to keep RST feet high level two machine cycle time. ALE/PROG: when access external storage, address latch allows the output level of the position for latch address byte. During the FLASH programming, this pin for input programming pulse. In peacetime, the ALE with a constant frequency cycle output is the pulse signal, the frequencies of the 1/6 oscillator frequency. So it can be used against external output pulse or used for timing purpose. However it is: whenever used for extern
