8051 - 3 ways to add STC model in Keil

【1】Database replacement method (STC official website method):

Note: This method is the simplest, but the disadvantage is that when selecting devices, you can only choose STC microcontrollers, and the original microcontrollers are gone, which is frustrating.

Steps:

First, back up the UV2.CDB (or UV3.CDB/UV4.CDB) file in the UV2 (or UV3/UV4) folder of the KEIL installation directory, and then replace it with the CDB file of the same name provided by the STC official website.

Note: If there is no UV4.CDB, you can rename "UV2.CDB (or UV3.CDB)" to "UV4.CDB" for use.

【2】New database adding method:

Note: By adding another MCU database, you can select STC MCU without affecting the use of the original database.

Steps:

① Download the STC database for Keil, rename it to STC.CDB and copy it to the Keil/UV2 directory. (If it is Kile3, it is UV3, Kile4 is UV4)

②Open the TOOLS.ini file in the Keil folder, type CDB0=UV2STC.CDB("STC") under [UV2] (that is, above [C51]), then save and exit to complete the addition. (If it is Kile3, it is UV3, and Kile4 is UV4)

Usage: When setting options for the target, click the Device page and select "STC" in Database.

When creating a new project, select "STC" in Select a CPU Date Base File.

Note: The default header files used in the STC database provided by Macrocrystalline's official website are REG51.H, REG52.H... (that is, the header files that can be quickly inserted by right-clicking are REG51.H, REG52.H...).

The right-click shortcut to insert the header file is as follows:

Therefore, if you want to conveniently use the "right-click quick insertion of the corresponding model header file", it is recommended that you modify the database or add the STC model yourself.

【3】Original database addition method (recommended):

Note: Add STC microcontrollers directly to the original database. Only add the STC models you need. It is simple and convenient. You can select STC microcontrollers without affecting the use of the original database.

 Put the header file STC15F104E.H in the C:KeilC51INCSTC directory (if there is no STC folder, build it yourself).

Note: If REGFILE=STC15F104E.H, do not use the following ("STC"), then the header file STC15F104E.H should be placed in the C:KeilC51INC directory.

【Supplementary explanation】

About database CDB files,

Kile4 is backward compatible. Kile4 can use and edit the database CDB files of Kile2 and Kile3.

Kile2 is not upward compatible and cannot use Kile4's database CDB file.

About UV4.CDB attachment:

The compressed package contains: UV4.cdb, STC folder, instructions for use.doc

① Directly replace the UV4.cdb in the C:KeilUV4 directory with the UV4.cdb in the compressed package. 

(The UV4.cdb in the compressed package has already collected the database that comes with Keil + STC database (including: STC15F104E, STC15F204EA...))
② Put the "STC" folder in the compressed package into the C:KeilC51INC directory. (The "STC" folder in the compressed package has already stored the header files of all STC series)

The purpose of step ②: You can right-click to quickly insert the header file corresponding to STC. For example:
