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.

NXP Semiconductor designed the LPC2400 microcontrollers around a 16-bit/32-bitARM7TDMI-S CPU core with real-time debug interfaces that include both JTAG andembedded Trace. The LPC2400 microcontrollers have 512 kB of on-chip high-speedFlash memory. This Flash memory includes a special 128-bit wide memory interface andaccelerator architecture that enables the CPU to execute sequential instructions fromFlash memory at the maximum 72 MHz system clock rate. This feature is available onlyon the LPC2000 ARM Microcontroller family of products. The LPC2400 can execute both32-bit ARM and 16-bit Thumb instructions. Support for the two Instruction Sets meansEngineers can choose to optimize their application for either performance or code size atthe sub-routine level. When the core executes instructions in Thumb state it can reducecode size by more than 30 % with only a small loss in performance while executinginstructions in ARM state maximizes core performance.

PIC单片机实用教程基础篇+提高篇 PIC单片机（Peripheral Interface Controller）是一种用来开发的去控制外围设备的集成电路（IC）。一种具有分散作用（多任务）功能的CPU。与人类相比，大脑就是CPU，PIC 共享的部分相当于人的神经系统。 PIC 单片机是一个小的计算机 PIC单片机有计算功能和记忆内存像CPU并由软件控制允行。然而，处理能力—存储器容量却很有限，这取决于PIC的类型。但是它们的最高操作频率大约都在20MHz左右，存储器容量用做写程序的大约1K—4K字节。 时钟频率与扫描程序的时间和执行程序指令的时间有关系。但不能仅以时钟频率来判断程序处理能力，它还随处理装置的体系结构改变（1*）。如果是同样的体系结构，时钟频率较高的处理能力会较强。 这里用字来解释程序容量。用一个指令（2*）表示一个字。通常用字节（3*）来表示存储器（4*）容量。一个字节有8位，每位由1或0组成。PIC16F84A单片机 的指令由14位构成。当把1K个子转换成位为：1 x 1,024 x 14 = 14,336位。再转换为字节为：14,336/(8 x 1,024) = 1.75K。在计算存储器的容量时，我们规定 1G 字节 = 1,024M 字节, 1M 字节 = 1,024K 字节, 1K 字节= 1,024 字节. 它们不是以1000为倍数，因为这是用二进制计算的缘故。 1*计算机的物理结构,包括组织结构、容量、该计算机的CPU、存储器以及输入输出设备间的互连。经常特指CPU的组织结构,包括它的寄存器、标志、总线、算术逻辑部件、指令译码与执行机制以及定时和控制部件。 2*指出某种操作并标识其操作数(如果有操作数的话)的一种语言构造 3*作为一个单位来操作(运算)的一个二进制字符串,通常比计算机的一个字短。 4*处理机内的所有可寻址存储空间以及用于执行指令的其它内存储器。 在计算存储器的容量时，我们规定 1G 字节 = 1,024M 字节, 1M 字节 = 1,024K 字节, 1K 字节= 1,024 字节. 它们不是以1000为倍数，因为这是用二进制计算的缘故。 用PIC单片机使电路做的很小巧变得可能。 因为PIC单片机可以把计算部分、内存、输入和输出等都做在一个芯片内。所以她工作起来效率很高、功能也自由定义还可以灵活的适应不同的控制要求，而不必去更换不同的IC。这样电路才有可能做的很小巧。

Nios 的用户定义接口逻辑实例 有许多人问我使用 Nios 的用户定义接口逻辑怎么用，想了几天决定设计一个实例来说明。该例为一个使用 user to interface logic 设计的 PWM 实例，其中包括三个文件： plus32.v 是一个为 32bit nios 设计的 pwm 实例。 plus16.v 是一个为 16bit nios 设计的 pwm 实例。 test.s 是一个使用中断调用 pwm 的汇编语言测试程序。以上模块和程序均调试通过，并可稳定工作。这里让大家参考是使大家通过该例来真正理解 user to interface logic 设计方法，和nios 中通过汇编调用中断的方法，所以超值喔。另外热烈欢迎大家的指导。 注：在设计 Nios 时，将你调用的 user to interface logic 插件重命名为 plus_0，这样我的 test.s 可不作任何改动，你就可用示波器通过 nios 的 plus 管脚观察到一个要求的输出。
