描述

ve4001s2T2B5

一個嵌入式系統(tǒng)如果有電源、晶振和CPU,那么這就是我們熟悉的最小系統(tǒng)。如果該嵌入式系統(tǒng)需要運行大點的操作系統(tǒng),那么不但需要CPU具有MMU,CPU還需要外接SDRAM和NANDFLASH。如果該cpu具有SDRAM和NANDFLASH控制器,那么在硬件設計上不用過多的考慮地址線的使用。如果沒有相關的控制器,那么需要注意地址線的使用。這部分在LAYOUT的時候是一個重點,究其原因就是要使相關信號線等長以確保信號的延時相等,時鐘和DQS的差分信號線走線。在布線的時候各種布線技巧需要綜合使用,例如與cpu對稱分布,菊花鏈布線、T型布線,這都需要依據(jù)內存的個數(shù)多少來進行選擇,一般來說個數(shù)越多,布線越復雜,但是知道其關鍵點,一切迎刃而解。? 一個嵌入式系統(tǒng)最重要的就是通過各種接口來控制外圍模塊,達到設計者預設的目的。常用的接口有串口(可用來連接藍牙,wifi和3G等模塊),USB接口、網(wǎng)絡接口、JTAG接口、音視頻接口、HDMI接口等等。由于這些接口與外部模塊連接,做好電磁兼容設計是重要的一項工作。除此之外,在LAYOUT的時候注意差分線的使用。這個功能之所以單獨列出來,是由于其可有可無。如果一個嵌入式系統(tǒng)只是作為一個連接器連接外圍設備模塊,通過相關接口連接到電腦主機或者直接掛在網(wǎng)絡上,那么屏幕就不需要了。但是如果做出來的是一個消費類產品,與用戶交互頻繁,這就不得不嘮叨幾句。
電容屏幕是嵌入式屏幕的首選,在電路設計中需要注意觸屏連接線和顯示屏連接線的布局。在走線的過程中盡量短的靠近主控cpu,同時注意配對信號走差分線,RGB控制信號走等長。各種信號走線間距遵循3W規(guī)則,避免相互干擾。在屏幕的設計中,一定要確保功率和防止干擾,以防屏幕閃屏和花屏現(xiàn)象的出現(xiàn)。

15天包退換 一年質保 大量現(xiàn)貨? 國內實力庫存商家


選擇深圳長欣,選擇放心,售后無憂大量現(xiàn)貨,當天順豐發(fā)貨!
主營:本特利,英維思,伍德沃德,福克斯波羅、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點經(jīng)驗。
1、先通讀一遍“系統(tǒng)手冊”(不管能不能看懂,先了解個大概,以便學習編程時查找);
2、由位控邏輯入手,逐漸增加定時、計數(shù)等條件,把或、與、非關系理順;
3、進而練習整數(shù)運算、實數(shù)運算、類型轉換;
4、量程轉換、PID調節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個物理回路驗證,比如變頻器+電機+測速傳感器);
5、循環(huán)、順序、跳轉等程序控制(盡量避免跳轉,非跳不可時也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅動器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學會一種至于其它的學習起來也就簡單了。
