打倒男孩《The Phoenix》的中英文歌词是什么《The Phoenix》是美国摇滚乐队Fall out boy演唱的歌曲，由帕特里克·斯特普、皮特·温兹、乔·特洛曼、安迪·赫里作词作曲，收录在打倒男孩第五张录音室专辑《Save Rock and Roll》中，于2013年7月16日作为专辑的第二支单曲发布。

歌曲于2014年4月13日在英国40强摇滚和金属单曲榜登顶。

2013年6月13日，歌曲获得英国Kerrang!音乐奖“最佳单曲”奖项。

《The Phoenix》创作背景打倒男孩主唱帕特里克·斯特普受到了前苏联作曲家肖斯塔科维奇的启发。

当欣赏肖斯塔科维奇的《第7号交响曲·第四部分》时，帕特里克·斯特普的思维被打开，于是斯特普准备创作该首歌曲。

歌曲对肖斯塔科维奇1941年发行的作品《Allegro Non Troppo》进行了采样;歌曲中的管弦乐片段对德国嘻哈艺人彼得·福克斯2008年发行的作品《Alles Neu》进行的采样。

歌词的灵感源自马特·狄龙执导的电影《大河边缘》。

1IntroductionThis application note describes fl ash programming routines for the HC9S08 and the ColdFire V1 family MCUs. Theseprogramming routines can be used to program and erase the fl ash memory. Because of differences between the 8-bit and 32-bit MCUs (fl ash module and address space) two software versions were created:•The fi rst version is for 8-bit MCUs. The HC9S08 family •The second version is for 32-bit MCUs. The ColdFire V1(MCF51JM, MCF51QE, MCF51AC, MCF51EM, and MCF51CN)This application note describes how to call each routine in the user software, performance, and return con fi rmation of the routine execution. The software fi les are available in the zip fi le AN3942SW, on the Freescale Semiconductor website, .There are basic structures of the fl ash memory on the HCS08and ColdFire V1 MCUs. The fl ash memory is divided into several smaller memory blocks that can be erased. These blocks are the smallest possible erasable areas. The size of these blocks depend on the individual implementation of the MCU families.For example the HCS08JM60 has 512 bytes and the MCF51JM128 has 1024 bytes block size.The most important part of the program is the correct location of the code sequence that executes the main fl ashprogramming.This code cannot run from the same fl ash memory because the flash module cannot write and read simultaneously.© Freescale Semiconductor, 2009 –.

(7)5For this reason the function doonstack that copies the relevant program sequence to the RAM memory was implemented. The code starts here and is executed.2API FunctionsThis section describes the structure and behavior of the API functions. These functions are available for the user and should be implemented in your main program. The API functions are described in detail in following chapter. Two different types of fl ash programming software was created for the API functions. These functions can be found in fi les doonstack.h.2.1HCS08 Version•FlashErase(const unsigned char * flash_destination);•FlashProg(const unsigned char * flash_destination, unsigned char data);•FlashProgBurst(const unsigned char * flash_destination, unsigned char * ram_source, unsignedchar length);Figure 1. Architecture of API functions for HCS08 MCUs2.1.1FlashEraseSyntax:•void FlashErase(const unsigned char * flash_destination);Parameters:•fl ash_destination —This pointer shows the block address that will be erased Description:•This function provides erasing the required memory block. Thefi rst address of the erasing block is shown by the pointer "fl ash destination."2.1.2FlashProgSyntax:•void FlashProg(const unsigned char * flash_destination, unsigned char data); Parameters:•fl ash_destination—This pointer shows the block address that will be programed•data—Here, variable data is saved that can be programed to the fl ash memory. The maximum length of the data is 1 byte. Description:•This function provides programming only one byte of memory block.2.1.3FlashBurstProgSyntax:•unsigned char FlashProgBurst(const unsigned char * flash_destination, unsigned char * ram_source, unsigned char length);Parameters:•fl ash_destination—This pointer shows the fi rst address of the memory block that can be programmed•ram_source—The source of the data array that is programmed to the fl ash memory•length—Length of the programed data arrayDescription:•The burst program function can be used to program a block of fl ash memory while crossing row boundaries within the fl ash array. This command has a 50% faster programming time than the basic program command.•The burst command saves the fl ash memory because the fl ash module starts only at the beginning of each cycle and is switched off at the end of this cycle.2.2ColdFire VersionThese functions can be found in the fi les doonstack.h for the HCS08, and doonstack_CFV1.h for the ColdFire MCUs.•PageErase(unsigned int * flash_destination);•BurstProg(unsigned int * flash_destination, unsigned int * ram_source, unsigned charlength);Figure 2.

You can choose between two types of MCU groups. The fi rst group includes the MCF51(JM, QE, AC, and CN) and the second group the MCF51(128 and 256). These two groups were created for different internal fl ash structures. For example, the MCF51EM256 MCU has two separate fl ash blocks (2 x 128 Kbytes) with two groups of fl ash module registers. This problem was solved by using a conditional compilation.; MCU = 1 -- MCF51(JM,QE,AC,CN); MCU = 2 -- MCF51(128(2x64kB),256(2x128kB))MCF51_JM_QE_CN_AC .EQU 1MCF51EM .EQU 2MCU .EQU MCF51_JM_QE_CN_ACSIZE .EQU 256•Add the relevant function (FlashErase, FlashProg) to the main application.int source_data[]={0x54454554, 0x45454545, 0x54545312, 0x54545454, 0x45445459, 0x4745457E, 0x54545447, 0x64545620, 0x24545158, 0x74545544};void Clock_Init(void){ // this is example of clock initialization for JM60MCGC2 = 0x00;MCGC1 = 0x06;MCGC3 = 0x01;MCGC4 = 0x02;/* bus clock 24 MHz */while(!MCGSC_LOCK){} /* wait until FLL is locked*/}void Flash_Clock_Init(void){FCDIV = 0x4E; // flash clock must be set up in the range (150-200 kHz)}void main(void){Clock_init(); // initialization of clock source on JM128Flash_Clock_Init(); // initialization of flash clock frequencylength_data = 10; // the length of the data is 10 bytesadress = 0x2000; // the source data will program to this addressDisableInterrupts;FlashErase(address); // erase functionFlashProg(address, source_data, length_data); //program functionEnableInterrupts;}4Application ExampleThis section discusses several examples that demonstrate how programming and erasing operations are performed on the HCS08 fl ash and ColdFire MCUs. All source code is written in assembler for minimum fl ash occupation. The source code for the HCS08 is about 350 bytes and for ColdFire about 900 bytes.4.1HCS08 Flash Routines and ColdFire Flash RoutinesIn the following code blocks the fl ash programming routines for erase and burst programming are shown. These short functions are situated permanently in the fl ash memory and serve for reading the address and setting fl ash parameters. These functions are executed before programing and erasing.FlashErase:; see Errata: SE133-FLASH : Unexpected Flash Block Protection ErrorsSTA ,X ;latch the unprotected address from H:XNOP ;brief delay to allow the command state machine to startSTA ,X ;intentionally cause an access error to abort this commandpsha ;adjust sp for DoOnStack entrylda #(mFPVIOL+mFACCERR) ;masksta FSTAT ;abort any command and clear errorslda #mPageErase ;mask pattern for page erase commandbsr DoOnStack ;finish command from stack-based subais #1 ;deallocate data location from stackrtsBefore every program cycle there must be a fl ash block that can be programmed to completely erase the fl ash memory.

Flash lightFlash LightIntroductionThe flash light, also known as a torch, is a portable handheld device that emits light from a bulb or an LED. Flashlights are commonly used in various situations, including for outdoor activities, emergencies, and everyday home use. This article will explore the different types of flashlights, their functions, and their history.History of FlashlightsThe history of flashlights dates back to the early 19th century when the first portable light sources were invented. Before the invention of flashlights, people relied on candles, oil lamps, and gas lamps for illumination. However, these light sources were not practical or portable enough for on-the-go use.In 1896, the first modern flashlight was patented by David Misell, an American inventor. This flashlight used an incandescent bulb and was powered by dry-cell batteries. It quickly became a popular tool among professionals like police officers, firefighters, and explorers.Types of Flashlights1. Incandescent Flashlights: These flashlights use a traditional tungsten filament bulb to produce light. They are typically less expensive than other types of flashlights but have a shorter battery life and less durability. Incandescent flashlights are still commonly used in everyday situations.2. LED Flashlights: LED (light-emitting diode) flashlights have gained popularity in recent years due to their energy efficiency, long battery life, and bright light output. LED bulbs are more durable and last longer compared to incandescent bulbs. They also have the advantage of being smaller in size, making them ideal for compact and lightweight flashlights.3. Rechargeable Flashlights: As the name suggests, rechargeable flashlights can be charged and reused multiple times. These flashlights are eco-friendly as they eliminate the need for disposable batteries. Rechargeable flashlights can bepowered by built-in rechargeable batteries or external power sources like USB or solar panels.4. Tactical Flashlights: Tactical flashlights are designed for military and law enforcement use. They are typically more rugged and durable, with features like high-intensity beams, strobe functions for self-defense, and waterproof construction. These flashlights are also preferred by outdoor enthusiasts for their reliability in harsh conditions.Functions and Uses of Flashlights1.
