Information in this article applies to:

  • µVision Version 2.40
  • µVision Version 3


When I try to open one of the Device Data Books in the µVision Project Window - Books Tab I get the following error message:

Can't open File xxx.PDF

From the message I can see that PDF file does not exist. How can I tell µVision the correct path to the databooks? Where should the books located?


The Keil Development CD-ROM contains the databooks of the most popular devices. However, these days we are supporting many devices. The databooks that we are using are available in the Device Database. You may download the relevant files to your harddisk.

In µVision you may use the dialog Project — Components, Environment, Books — Book Tab to manage the books that appear in the Project Window - Books Tab. The dialog allows you to specify the Default Root for Device Specific books (which is typically the CD-ROM drive) and to add specific books on any section of the Books window.
