第八章 labview的編程技巧 本章介紹局部變量、全局變量、屬性節(jié)點(diǎn)和其他一些有助于提高編程技巧的問(wèn)題,恰當(dāng)?shù)剡\(yùn)用這些技巧可以提高程序的質(zhì)量。 8.1 局部變量 嚴(yán)格的語(yǔ)法盡管可以保證程序語(yǔ)言的嚴(yán)密性,但有時(shí)它也會(huì)帶來(lái)一些使用上的不便。在labview這樣的數(shù)據(jù)流式的語(yǔ)言中,將變量嚴(yán)格地分為控制器(Control)和指示器(Indicator),前者只能向外流出數(shù)據(jù),后者只能接受流入的數(shù)據(jù),反過(guò)來(lái)不行。在一般的代碼式語(yǔ)言中,情況不是這樣的。例如我們有變量a、b和c,只要需要我們可以將a的值賦給b,將b的值賦給c等等。前面所介紹的labview內(nèi)容中,只有移位積存器即可輸入又可輸出。另外,一個(gè)變量在程序中可能要在多處用到,在圖形語(yǔ)言中勢(shì)必帶來(lái)過(guò)多連線,這也是一件煩人的事。還有其他需要,因此labview引入了局部變量。

The LPC2292/2294 microcontrollers are based on a 16/32-bit ARM7TDMI-S CPU with real-time emulation and embedded trace support, together with 256 kB of embedded high-speed flash memory. A 128-bit wide memory interface and a unique accelerator architecture enable 32-bit code execution at the maximum clock rate. For critical code size applications, the alternative 16-bit Thumb mode reduces code by more than 30 pct with minimal performance penalty. With their 144-pin package, low power consumption, various 32-bit timers, 8-channel 10-bit ADC, 2/4 (LPC2294) advanced CAN channels, PWM channels and up to nine external interrupt pins these microcontrollers are particularly suitable for automotive and industrial control applications as well as medical systems and fault-tolerant maintenance buses. The number of available fast GPIOs ranges from 76 (with external memory) through 112 (single-chip). With a wide range of additional serial communications interfaces, they are also suited for communication gateways and protocol converters as well as many other general-purpose applications. Remark: Throughout the data sheet, the term LPC2292/2294 will apply to devices with and without the /00 or /01 suffix. The suffixes /00 and /01 will be used to differentiate from other devices only when necessary.

Abstract: The reality of modern, small form-factor ceramic capacitors is a good reminder to always readthe data sheet. This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V,imply nothing about voltage coefficients. Engineers must check the data to know, really know, how aspecific capacitor will perform under voltage.

本source code 為s3c4510的bootloader,不同於其他的s3c4510的bootloader,這個(gè)bootloader花了很多功夫,完全不需要看data sheet就可以更改register,當(dāng)週邊chip改變時(shí),更改bootloader可以很快就完成。只要修改init_gun.h這個(gè)文件即可。
