用于汽車無線電和信息娛樂系統(tǒng)的8V開關(guān)電源

Abstract: This application note illustrates an intermediate 8V switching power supply for an automotive radio and infotainment system.The design withstands the complete automotive input voltage range (including cold crank and load dump conditions), assuring a stable8V supply for common subsystems such as a CD driver, LCDs, and a radio module in modern infotainment systems. To avoiddisturbance in the AM and FM bands, the switching power supply runs at a fixed frequency of 2MHz, enabling an ideal solution forradio systems.

STC89C5X單片機(jī)“看門狗”原理、詳細(xì)說明和演示程序

“看門狗定時(shí)器”是這樣一種東西，從功能上說它可以讓微控制器在意外狀況下（比如程序陷入死循環(huán)）重新回復(fù)到系統(tǒng)上電狀態(tài)，以保證系統(tǒng)出問題的時(shí)候重啟一次。就跟我們用電腦一樣，死機(jī)了你就按一下reset鍵重啟一次電腦，看門狗就是負(fù)責(zé)干這個(gè)事兒的。它是52單片機(jī)增加的一個(gè)功能，以前Intel 8031、……、AT89C51時(shí)代單片機(jī)片內(nèi)都沒有“看門狗”功能，需要我們外擴(kuò)看門狗芯片，比如X5045。很多人初次接觸丌太理解怎么用，書上也講的含含糊糊，故意說的很復(fù)雜很玄妙（可能是現(xiàn)在寫書人的通病，生怕寫的簡單的別人覺得他沒水平）。其實(shí)要是說明白點(diǎn)：“看門狗”就是一個(gè)計(jì)數(shù)器，由于位數(shù)有限計(jì)數(shù)器能夠裝的數(shù)值是有限的(比如8位的最多裝256個(gè)數(shù)、16位的最多裝65536個(gè)數(shù))，從開啟“看門狗”那刻起，它就開始丌停的數(shù)機(jī)器周期，數(shù)一個(gè)機(jī)器周期就計(jì)數(shù)器加１，加到計(jì)數(shù)器盛丌下了（術(shù)語叫溢出）就就產(chǎn)生一個(gè)復(fù)位信號，重啟系統(tǒng)。

FET430PIF自制資料

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.
