<delect id="o4a8w"></delect> <sup id="o4a8w"></sup> The STWD100 watchdog timer circuits are self-contained devices which prevent systemfailures that are caused by certain types of hardware errors (non-responding peripherals,bus contention, etc.) or software errors (bad code jump, code stuck in loop, etc.).The STWD100 watchdog timer has an input, WDI, and an output, WDO (see Figure 2). Theinput is used to clear the internal watchdog timer periodically within the specified timeoutperiod, twd (see Section 3: Watchdog timing). While the system is operating correctly, itperiodically toggles the watchdog input, WDI. If the system fails, the watchdog timer is notreset, a system alert is generated and the watchdog output, WDO, is asserted (seeSection 3: Watchdog timing).The STWD100 circuit also has an enable pin, EN (see Figure 2), which can enable ordisable the watchdog functionality. The EN pin is connected to the internal pull-downresistor. The device is enabled if the EN pin is left floating.

On-Line MCMC Bayesian Model Selection This demo demonstrates how to use the sequential Monte Carlo algorithm with reversible jump MCMC steps to perform model selection in neural networks. We treat both the model dimension (number of neurons) and model parameters as unknowns. The derivation and details are presented in: Christophe Andrieu, Nando de Freitas and Arnaud Doucet. Sequential Bayesian Estimation and Model Selection Applied to Neural Networks . Technical report CUED/F-INFENG/TR 341, Cambridge University Department of Engineering, June 1999. After downloading the file, type "tar -xf version2.tar" to uncompress it. This creates the directory version2 containing the required m files. Go to this directory, load matlab5 and type "smcdemo1". In the header of the demo file, one can select to monitor the simulation progress (with par.doPlot=1) and modify the simulation parameters.

In this book, you will acquire a comprehensive understanding of GIMP Toolkit (GTK+) that can help you to become a proficient graphical programmer. Before continuing, you should be aware that this book is aimed at C programmers, so we will jump right into using GTK+. Time will not be spent covering information you already know.

MS2 程序分析 Lldwsw 一：下載MS2.RAR 壓縮包解壓縮后可以看到如下界面： 第一項(xiàng)為MS2 軟件包，第二項(xiàng)為SourceInsight3.0，它是一款非常優(yōu)秀的C 語(yǔ)言編輯器，目 前各個(gè)大公司，比如華為等都用它，手機(jī)行業(yè)幾乎無(wú)一例外。它的作用是代替Keil 的編輯 環(huán)境，因?yàn)镵eil 的編輯環(huán)境太難看了，并且使用也不方便，用它來(lái)看程序，查找函數(shù)特別 容易，以下是它的界面： 各位可以看到，它里面不同的關(guān)鍵字的顏色都是不同的，看上去很舒服，最主要的還是它的 查找功能，比如要看MSTimerStart 的函數(shù)原型，但不知道他在那個(gè)地方，雙擊函數(shù)名，右 擊后出現(xiàn)屬性，點(diǎn)“jump to Definition”，就可以看到函數(shù)原型，這個(gè)功能Keil 下也有，還 有一個(gè)Keil 下沒(méi)有的，就是這個(gè)函數(shù)被誰(shuí)調(diào)用了，雙擊函數(shù)名，右擊后出現(xiàn)屬性，點(diǎn)“jump to Caller”。 具體請(qǐng)參考SourceInsight 使用說(shuō)明，也就是第四項(xiàng)，第三項(xiàng)是周立功的DP-51 電路圖,因?yàn)? MS2 的設(shè)計(jì)本身是不倚賴外設(shè)的，所以沒(méi)有加外部接口，直接用串口來(lái)演示，如下圖： 大家可以看到liweifeng， test1，test2，test3 在不停的打印，這是四個(gè)偽任務(wù)，按一定的時(shí) 候間隔打印，我們將在后面分析。當(dāng)然按鍵等都可以在處理字符串欄中輸入，在接收窗口顯 示。 以
