A complete set of bit banged, software driven I2C routines I created for any PIC device - and they work!! These functions are single master only functions, and are ideal for communicating with things like EEPROMs, LCD Drivers, ADC Converters etc

一般我們要根據數據庫的紀錄變化時,進行某種操作。我們習慣的操作方式是在程序中不停的查詢表,判斷是否有新紀錄。這樣耗費的資源就很高,如何提高這種效率,我想在表中創建觸發器,在觸發器中調用外部動態連接庫通過消息或事件通知應用程序就可實現。而master的存儲過程中最好能調用外部的動態連接庫,我們在觸發器中調用master的存儲過程即可。本文提供了動態庫與存儲過程的具體實現

可以支持連續讀寫的i2cslave源碼,很適合作為master的testbench來用

本程序是在網友vagrant的升級程序上增加了SQL數據庫的更新升級功能,系統中采用了ACCES來存儲數據更新的指令,從而達到逐步執行SQL代碼的功能,因為在SQL中要創建表、存儲過程、視圖等對象時,需要刪除原有老的對象,但是SQL不支持將這些指令存放在一起,從而導致出錯。所以用ACCES來存儲數據了 例中將在master中創建p_killspid,該程序過程是用來恢復與備份數據的一部分。 MENTOROUSER.INI為數據服務地址,曾經有網友問過我如何做服務登錄的系統,此文件是個關鍵,具體的連接請參考代碼 SQLTEXT.MDB為數據庫更新用的文件,請自行修改記錄,但是記錄先后順序一定要根據指令的先后順序來添加。 mentoro.htm為存放在網站上的文件,具體內容自已改吧。(您也可以用INI文件) CHIS.INI為更新配置文件

jsf做的增刪改的例子,比較短小,代碼不多,但展現了做master-detail時的思路,可以參考

VHDL實現SPI功能源代碼 -- The SPI bus is a 3 wire bus that in effect links a serial shift -- register between the "master" and the "slave". Typically both the -- master and slave have an 8 bit shift register so the combined -- register is 16 bits. When an SPI transfer takes place, the master and -- slave shift their shift registers 8 bits and thus exchange their 8 -- bit register values.

如文件名,在LPC2138上的I2C的master發送接受測試程序。里面的readme.txt(英)有詳細說明。

Avalon Interface Specification,The Avalon interface specification is designed to accommodate peripheral development for the system-on-a-programmable-chip (SOPC) environment. The specification provides peripheral designers with a basis for describing the address-based read/write interface found on master and slave peripherals, such as microprocessors, memory, UART, timer, etc.

An AHB system is made of masters slaves and interconnections. A general approach to include all possible "muxed" implementation of multi layered AHB systems and arbitrated AHB ones can be thought as an acyclic graph where every source node is a master, every destination node is a slave and every internal node is an arbiter there must be one and only one arc exiting a master and one or more entering a slave (single slave verus multi-slave or arbitrated slave) an arbiter can have as many input and output connections as needed. A bridge is a special node that collapses one or more slave nodes and a master node in a new "complex" node.

一般使用PC Based Controller 都是當作現場設備的一種,也就是要接受 主系統的命令,做一些操作控制。以Modbus 來看屬于Slave 的角色,隨 時等待接收Modbus master 的Query Message,然后依據內容做控制,最后 將控制結果以Response Message 回傳。本章將以ICP 7524 及ICP 7188E5 等 兩種設備分別設計Modbus RTU、ASCII 及Modbus/TCP 的Slave 應用程序, 讀者可以將此兩種程序的架構再延伸設計至各種實際應用程序。
