STM32时钟配置及相关问题

Ⅰ、写在前面最近有很多朋友问： 1.我的USART串口打印出来的数据是乱码？ 2.我的TIM定时器延时或定时不准确？常见可能原因： 1.晶振问题：外部晶振不起振、或频率与配置不匹配。 2.软件问题：分频、倍频、时钟源选择等。总结来说，主要还在于软件的问题。因为即使没有外部晶振，也可以使用内部晶振。其实，软件的问题是容易得到解决的，只要你了解了STM32时钟配置里面具体内容就知道了...[详细]
由PLC到PAC：该如何改进您的系统？

　　在过去的几十年里，可编程逻辑控制器（ PLC ）一直被广泛用于自动化领域，而在可预知的未来，PLC仍将长盛不衰。面向离散控制而设计PLC的实际上已经成为工业领域一个具有伟大意义的统治性工具。　　然而，随着工业用机器和工厂系统的复杂性的增加，PLC已经很难而且也不可能成为完成所有自动化任务。现在的自动化系统已经超越了PLC的功能范围，使得工业机器领域的工程师必须在自动化系统中集成更多...[详细]
英特尔要转型Fabless？计划买点晶圆厂

英特尔准CEO杰辛格（Pat Gelsinger）将在2月15日上任，华尔街分析师认为，杰辛格「对技术具备敏锐认知，有望大刀阔斧，协助英特尔未来数年顺利转型为无晶圆厂（ Fabless），专注先进设计技术与专利授权。以此来看，英特尔未来处分没有领先技术与经济规模的美国部分晶圆厂，将会是合理选项。一旦英特尔出售美国部分晶圆代工厂，分析师点名，三星集团或台积电可能是潜在的买家。不过，相对三星集...[详细]
技术新名词—聚合物传感器
