    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

    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.
