Keil uVision

Keil uVisionIt is a 51 series compatible microcontroller C language software development system produced by the American Keil Software company. It is developed using a syntax close to the traditional C language. Compared with assembly, C language has obvious advantages in functionality, structure, readability, and maintainability, so it is easy to learn and use, and greatly improves work efficiency and project development cycle. It can also embed assembly, and you can embed it in key positions to make the program achieve work efficiency close to assembly.

Keil uVision FAQ:

​ ​ 1. When commenting in keil4, why can't I enter Chinese characters? They are all boxes?

The processing method: Edit->Configuration, click the Colors&Fonts tab, select EditorCFiles in the Window list, select the font Courier on the right, UsecolorinComments cannot be checked.

After completing the above operations, let me compare before and after:

The display effect is as follows:

1. Before operation:

If the black line in the following annotation is a box, the operation is the same, but the font must be changed appropriately (eg: Song Dynasty or New Song Dynasty will work).

2. Display effect after operation:

Through the display, we can see intuitively that the text in the annotation has been clearly displayed.

​ ​ 2. Change the keyword color:

Method: Edit->Con

Keil uVision usage tips:

1. Installation of experimental simulation board

These two simulation experiment boards are actually two dll files, named ledkey.dll and simboard.dll respectively. During installation, you only need to copy these two or one file to the c51bin folder of the keil software as needed.

2. Use of experimental simulation board

To use the simulation board, you must set up the project. The setting method is to click Project->OptionforTarget‘Target1’ to open the dialog box, then select the Debug tab, and enter -d file name in the edit box after Dialog:Parameter:. For example, if you want to use ledkey.dll (the first simulation board) for debugging, enter -dl

3. Instance debugging

The following takes a slightly complex program as an example to illustrate the use of keyboard and LED display experimental simulation boards. What this program implements is a controllable flowing water lamp. The key connected to P3.2 is the start key. Press this key to make the lights start to flow (from top to bottom). The key connected to P3.3 is the stop key. Press this key to stop the flow and all lights will be dark. The key connected to P3.4 is the up key. Press this key to make the lights flow from top to bottom. The key connected to P3.5 is the down key. Press this key to make the lights flow from bottom to top.
