The P89LPC938 is a single-chip microcontroller, available in low cost packages, based on
a high performance processor architecture that executes instructions in two to four clocks,
six times the rate of standard 80C51 devices. Many system-level functions have been
incorporated into the P89LPC938 in order to reduce component count, board space, and
system cost.
jsp和xml。XML and JSP are two important tools available in producing a web application. This chapter examines the
potential of mixing these two technologies in order to enhance the capabilities of JSP. While this chapter will
cover many things about XML, this chapter will not attempt to teach XML. Instead it focuses on how JSP and
XML can be used together as a highly flexible and powerful tool. In general the usage of XML in these
examples will be kept simple and should cause no problems for users who are starting XML.
December 19, 2006 - Ant 1.7.0 available
Apache Ant 1.7.0 is now available for download.
Ant 1.7 introduces a resource framework. Some of the core ant tasks such as <copy/> are now able to process not only file system resources but also zip entries, tar entries, paths, ... Resource collections group resources, and can be further combined with operators such as union and intersection. This can be extended by custom resources and custom tasks using resources.
Ant 1.7 starts outsourcing of optional tasks to Antlibs. The .NET antlib in preparation will replace the .NET optional tasks which ship in Ant. Support for the version control system Subversion will be only provided as an antlib to be released shortly.
Ant 1.7 fixes also a large number of bugs.
Ant 1.7 has some initial support for Java6 features.
This function checks the mailbox to see if a message is available. Unlike OSMboxPend(),
OSMboxAccept() does not suspend the calling task if a message is not available.
調試通道例子。DCC is available on ARM cores which contain EmbeddedICE logic, e.g. ARM7TDMI,
ARM9TDMI, etc. DCC is accessed by the target via coprocessor 14 using the
ARM instructions MCR and MRC.
The two assembler source files provided are:
outchan.s for Target to debugger communication
inchan.s for Debugger to target communication
