The MSP-FET430PIF is a Parallel Port interface (does not include target board) that is used to program and debug MSP430 FET tools and test boards through the JTAG interface. This interface is included in our FET tools, but sold without the development board. This interface uses a Parallel PC Port to communicate to the Debugger Software (IAR Kickstart software included) running on the PC. The interface uses the standard 14 pin header to communicate to the MSP430 device using the standard JTAG protocol. The flash memory can be erased and programmed in seconds with only a few keystrokes, and since the MSP430 flash is extremely low power, no external power supply is required. The tool has an integrated software environment and connects directly to the PC which greatly simplifies the set-up and use of the tool. The flash development tool supports development with all MSP430 flash parts. Features MSP430 debugging interface to connect a MSP430-Flash-device to a Parallel port on a PC Supports JTAG debug protocol (NO support for Spy-Bi-Wire (2-wire JTAG) debug protocol, Spy-Bi-Wire (2-wire JTAG) is supported by MSP-FET430UIF) Parallel Port cable and a 14-conductor target cable Full documentation on CD ROM Integrated IAR Kickstart user interface which includes: Assembler Linker Limulator Source-level debugger Limited C-compiler Technical specifications: Backwardly compatable with existing FET tool boards.

Keil C251设计软件V3.11(4k代码限制） keil c251 v3.11 demo版的安装说明：安装方法是先将V3.11安装程序用winzip解压缩到某个目录下。（不要直接点击setup.exe安装），比如解压缩到c:\c251然后执行c:\c251\setup\setup.exe 安装程序，这个程序会让你选择安装Eval Version版还是Full Version版，选择Eval Version版进行安装 安装好之后就可以使用，但有代码大小的限制。需要无限制的版本，请购买正版软件。 C251是intel公司的16位单片机，指令兼容51的单片机。8位单片机风靡了20年，下一个20年应该是16位单片机的世界。

The CAT28LV64 is a low voltage, low power, CMOS Parallel EEPROM organized as 8K x 8−bits. It requires a simple interface for in−system programming. On−chip address and data latches, self−timed write cycle with auto−clear and VCC power up/down write protection eliminate additional timing and protection hardware. DATA Polling and Toggle status bit signal the start and end of the self−timed write cycle. Additionally, the CAT28LV64 features hardware and software write protection.

以典型的9S08 系列为例，当你选择了一个MCU 型号后，在图1-4 右侧会显示出所有针对该型号芯片可用的项目调试场景。其中：Full Chip Simulator”是芯片全功能模拟仿真，即无需任何目标系统的硬件资源，直接在你的PC 机上模拟运行单片机的程序，在模拟运行过程中可以观察调试程序的各项控制和运行流程，分析代码运行的时间，观察各种变量，等等。CW 提供了功能强大的模拟激励功能，可以在模拟运行时模拟一些外部事件的输入，配合程序调试；P&E Multilink/Cyclone Pro”是基于P&E 公司的硬件调试工具实现实时在线硬件调试。实际就是我们经常说的BDM 调试。BDM 调试是基于芯片本身内含的在线调试功能，可实现程序下载，单步／全速运行，可以设若干个断点，可以观察和修改任意寄存器或RAM 内存空间。BDM 几乎是开发飞思卡尔8 位（9S08 和RS08 系列）、16 位（9S12 系列）和32 位（Coldfire V1 系列）单片机的标准调试模式，运用最为广泛；SofTec HCS08”是另外一家SofTec 公司提供的硬件调试工具，国内使用较少；HCS08 Serial Monitor”是基于芯片串口的监控调试开发模式。由于开发效率较低，现在几乎无人使用。

Luminary Micro provides an analog-to-digital converter (ADC) module on some members of theStellaris microcontroller family. The hardware resolution of the ADC is 10 bits; however, due to noiseand other accuracy-diminishing factors, the true accuracy is less than 10 bits. This application noteprovides a software-based oversampling technique, resulting in an improved Effective Number OfBits (ENOB) in the conversion result. This document describes methods of oversampling an inputsignal, and the impact on precision and overall system performance.

The Philips family of Multiplexers and Switches consists of bi-directional translating switches controlled via the I2C or SMBus to fan out an upstream SCL/SDA pair to 2, 4 or 8 downstream channels of SCx/SDx pairs. The Multiplexers allow only one downstream channel to be selected at a time, while the Switches allow any individual downstream channel or combination of downstream channels to be selected, depending on the content of the programmable control register. Once one or several channels have been selected, the device acts as a wire, allowing the master on the upstream channel to send commands to devices on all the active downstream channels, and devices on the active downstream channels to communicate with each other and the master. External pull-up resistors are used to pull each individual channel up to the desired voltage level. Combined interrupt output and hardware reset input are device options that are featured.
