1.The C Programming Language is a powerful, flexible andpotentially portable high-level programming language. 2.The C language may be used successfully to create a programfor an 8-bit MCU, but to produce the most efficient machinecode, the programmer must carefully construct the C Languageprogram.3.The programmer must not only create an efficient high leveldesign, but also pay attention to the detailed implementation.

P89V51RD2具有IAP(在应用中编程)功能,用户通过在应用程序中调用IAP子程序,可实现有选择的对FLASH块进行擦除和编程。P89V51RD2的bootrom区为0000H~1FFFH,为避免和用户的程序代码发生冲突,调用IAP功能的代码要从地址2000H以后开始存放。以下讲述在Keil μVision2下用C语言和汇编语言混编的办法实现IAP调用的方法。

The PCA9534 is a 16-pin CMOS device that provide 8 bits of General Purpose parallel Input/Output (GPIO) expansion for I2C-BUS/SMBus applications and was developed to enhance the NXP Semiconductors family of I2C-BUS I/O expanders. The improvements include higher drive capability, 5 V I/O tolerance, lower supply current, individual I/O configuration, 400 kHz clock frequency, and smaller packaging. I/O expanders provide a simple solution when additional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.

The PCA9540B is a 1-of-2 bidirectional translating multiplexer, controlled via the I2C-BUS.The SCL/SDA upstream pair fans out to two SCx/SDx downstream pairs, or channels.Only one SCx/SDx channel is selected at a time, determined by the contents of theprogrammable control register.
