PCB设计问题集锦
问:PCB图中各种字符往往容易叠加在一起,或者相距很近,当板子布得很密时,情况更加严重。当我用Verify Design进行检查时,会产生错误,但这种错误可以忽略。往往这种错误很多,有几百个,将其他更重要的错误淹没了,如何使Verify Design会略掉这种错误,或者在众多的错误中快速找到重要的错误。 答 ...
接口技术 XAPP904 - CoolRunner-II特性LCD模块接口
 
There are many manufacturers of dot matrix LCD modules. However, most of these displaysare similar. They all have on-board controllers and drivers capable of displaying alpha numericsand a wide variety of other symbols (including Japanese "Katakana" characters). The internaloperation of L ...
