originally to provide easy on-board communications between a CPU and various peripheral chips in a TV set. Today, it is widely used in varieties of embedded systems to connect low speed peripherals (external EEPROMs, digital
between SMBus is that it limits speeds from 10kHz to 100kHz, while I2C can support devices from 0kHz to 5MHz. SMBus includes a clock timeout mode which makes low-speed operations illegal, although many SMBus devices will support it anyway to maximize interoperability with embedded I2C ...
由于P89C664带有硬件I2C接口,因此我们用它作为从器件接收I2C总线上的数据,Philips公司在相关的技术资料中给出了标准的I2C接口控制程序包。其实也可根据P89C664的资料自己来编写I2C接口的控制程序,不过Philips公司提供的参考程序很值得我们学习、研究。下面程序中用的就是Phlips公司推出的I2C接口控制程序,为了更适用于接...

Among many different slave-master protocols, I2C and SPI protocols are the common serial communication protocols widely found in embedded devices. Both protocols let the microcontroller/microcomputer take the master role and allow interfacing of several sensors and embedded blocks on a common bus. This...
这种专用的ISP下载软件可以在各公司的网部上免费下载到。P89C664的ISP软件可在Philips公司的网站上下载。当然,如果你有兴趣也可以自己设计一个个性化的ISP下载软件,因为Philips公司对ISP的各种编程指令是开放的。 IAP(In Application Programming),即在应用中程序。就是说,MCU自己可以获取新的代码并对自己重新编程。这...

This API is easy to understand, much like the ANSI C library functions, (e.g., there is no unnecessary entanglement with the Windows messaging subsystem like development kits for some other embedded tools). First, choose the Rosetta bindings appropriate for the programming language. Different ...
