This a small hack I wrote to bypass the "No previous installation!" error of Microchip s C18 Upgrade. Simply run C18Fake and select your C18 installation directory (create if necessary) and click Save button. A "fake" file will now be created into that directory, and this will fool the Upgrade into thinking you already have a former legit installation. After that you run the C18 Upgrade setup and select the same directory you created/selected before. Your installation will now begin installing the full C18 package.

应用软件根据bypass信号的值来决定是否使用PLL。如果使用PLL，那么它总是输出一个200MHz的时钟信号，并且联合系统分频器（SYSDIV）共同产生系统时钟。馈送到PWM模块的时钟由系统时钟提供。如果应用中需要较低的PWM时钟，那么在时钟信号到达PWM模块前可以使用PWM分频器（PWMDIV）先分频。ADC时钟使用一个时钟源（source）为200MHz的常量分频器，这就意味着如果要使ADC时钟的工作频率保持在14-18MHz范围内，必须使能并使用PLL。

This design uses Common-Emitter Amplifier (Class A) with 2N3904 Bipolar Junction Transistor. Use “Voltage Divider Biasing” to reduce the effects of varying β (= ic / ib) (by holding the Base voltage constant) Base Voltage (Vb) = Vcc * [R2 / (R1 + R2)] Use Coupling Capacitors to separate the AC signals from the DC biasing voltage (which only pass AC signals and block any DC component). Use bypass Capacitor to maintain the Q-point stability. To determine the value of each component, first set Q-point close to the center position of the load line. (RL is the resistance of the speaker.)

华为敏捷园区解决方案终端安全技术白皮书(Forescout)1 用户准入检查，保证身份合法： 在用户访问网络访问之前验证用户的身份，只有合法的用户才允许接入网络。这就是 基于用户身份的准入机制，包括 802.1x,Portal,MAC bypass 这几种典型的认证方式。 准入检查由客户端+网络设备+AAA 服务器组成。在 Agile Campus 解决方案中，AAA 服务器可以使用自研的 Agile Controller-Campus 1.0，也可以与第三方 Server 对接，例 如 Cisco ISE 系统。 2 终端合规性检查，保证终端合规： 检查用户使用的终端是否符合企业制定的安全策略，例如防病毒和操作系统补丁策 略。可疑或有问题的主机将被隔离或限制网络接入范围，直到它经过修补或采取了相 应的安全措施为止。 终端合规检查由客户端+服务器组成，该系统可以独立部署。若需要将合规检查结果作 为 NAC 控制条件，AAA 系统必须与终端合规检查服务器实现联动。 在 Agile Campus 解决方案中，终端合规检查采用集成第三方厂家方式实现。 3 业务随行，保证用户业务一致性体验 基于安全组的策略规划，实现全网策略的统一部署与自动同步，确保全网策略一致， 让用户自由移动时享受一致的业务体验。 业务随行由网络设备+AAA 服务器+策略服务器组成。在 Agile Campus 解决方案中，若 客户希望同时部署终端合规检查和业务随行，需要部署 Agile Controller-Campus 1.0， 同时集成合规检查服务器。
