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.(This function checks the mailbox to see if a message is available.

51系列单片机的UCOSII......压缩包一个.还不错吧-51 Series MCU UCOSII ...... compressed one. It is also good

读者优先问题。操作限制：1）写-写互斥；2）读-写互斥；3）读-读允许； 读者优先的附加限制：如果一个读者申请进行读操作时已有另一读者正在进行读操作，则该读者可直接开始读操作。-readers priority. Operating restrictions : a) write-write contradict; 2) read-write mutually exclusive; 3) Reading-Reading allowed; Readers priority to the additional restrictions : If an application for readers read another operation has been under way readers read operation, the reader can directly read operation began.

UCOS的源码，它的硬件基础是80186，只要你的电脑只要是INTEL的CPU，就可以在你的电脑上面正常运行，你也可以把它移植到你的MCU，所以这个源码是研究UCOS的最佳选择。-UCOS the source, and its hardware is based on 80,186, as long as your computer as long as it is INTEL" s CPU, on your computer in the normal operation of the above, you can transfer it to your MCU, so the source is to examine the UCOS the best choice.

示波器，用ARM实现，重点在液晶的算法上(Oscilloscope with ARM to achieve, with a focus on the LCD of the algorithm)

UCGUI实际的性能由许多因素决定, 如处理器/编译器/内存模 式/优化程度/配置/LCD 控制器连接方式等. UCGUI 在典型目标系统上的 性能测试参数和资源占用的分析报告, 通过报告你也可以获知在其它大部分目标系统上 情况(UCGUI actual performance is determined by many factors, such as the processor/compiler/memory mode/optimize the degree/configuration/LCD controller connection. UCGUI typical target system performance test parameters and resource consumption analysis report by report You can also be informed of the situation in most of the other on the target system)
