CANopen is a networking system based on the CAN serial bus. CANopen assumes that the device’s hardware has a CAN transceiver and CAN controller as specified in ISO 11898. CANopen profile family specifies standardized communication mechanisms and device functionality. The profile family is available and maintained by CAN in Automation (CiA), the international users’ and manufacturers’ group and may be implemented license-free.

Application Note Abstract This Application Note introduces a complete and detailed PSoC® project. Telephone Call Logger keeps the detailed record of approximately 945 phone calls (7-digit number is assumed to be one phone call) including date, start time and the duration of the phone call in the PSoC device. Users can get this detailed report into the PC environment by using free software, which is included in the project file. When records reach near full capacity of the Flash memory, an LED will turn on to show that it is necessary to backup the data. Software gets the data from PSoC, organizes it and prepares a printable version. Additionally, it sends the date and time information to the PSoC. The external parts in this project can be obtained easily in the market.

NAME Control_AT24Cxx This collection of routines allows an AT89C2051 microcontroller to read and write the AT24Cxx family of serial CMOS EEPROMS. This version of the code is compatible only with the AT89C2051 due to the location of the data buffer and stack in RAM. The code may be modified to work with the AT89C1051 by relocating or resizing the buffer and stack to fit into the smaller amount of RAM available in the AT89C1051. Note that the minimum size of the buffer is determined by the page size of the AT24Cxx.

監控程序(Monitor)的主要功能是對應用系統硬件及底層軟件進行調試,也稱為Debug程序,是最基本的調試工具。MC9S12DG128的Flash有128K,RAM有8K,而監控程序源代碼占用不到3K FLASH,占用23字節RAM。這對用戶程序的空間影響并不大。異步串行口是要用來做與PC通訊服務的,監控程序可以用,應用程序當然也可以使用。

這是一個比較典型的PID處理程序,在使用單片機作為控制cpu時,請稍作簡化,具體的PID參數必須由具體對象通過實驗確定。由于單片機的處理速度和ram資源的限制,一般不采用浮點數運算,而將所有參數全部用整數,運算 到最后再除以一個2的N次方數據(相當于移位),作類似定點數運算,可大大提高運算速度,根據控制精度的不同要求,當精度要求很高時,注意保留移位引起的“余數”,做好余數補償。這個程序只是一般常用pid算法的基本架構,沒有包含輸入輸出處理部分。

一個單片機應用系統的硬件電路設計包含兩部分內容:一是系統擴展,即單片機內部的功能單元,如ROM、RAM、I/O、定時器/計數器、中斷系統等不能滿足應用系統的要求時,必須在片外進行擴展,選擇適當的芯片,設計相應的電路。二是系統的配置,即按照系統功能要求配置外圍設備,如鍵盤、顯示器、打印機、A/D、D/A轉換器等,要設計合適的接口電路。
