The laser beam of laser pointer with remote control

Thus RF  laser pointer  with remote control is more popular among customers.
Figure 4.1 and then select the path you want to save, enter the name of the project file, and then click the "Save" button. A pop-up dialog box, and asked to select the MCU models. Here can be used by the microcontroller, Keil supports almost all 51-core microcontroller, Atmel's 89C51 instructions under Figure 2: Figure 4.2 First Atmel Corporation, and then click the left "+" sign to select the AT89C51 after the right-hand column of the "Options" dialog box, select the "Output" tab bar, set up in which the press as shown in Figure 3. 18 Figure 4.3. To establish a new ASM assembly language program and compile ① in the menu bar, click "File" menu, and then in the drop-down menu, click "New" option, or just click the shortcut icon in the toolbar to create a new editing window. The laser beam of  laser pointer  with remote control is electricity-saving.
The cursor blinking in the edit window, then enter the user's application. Recommended to first save the blank document, click the "File" menu, select "Save As" option in the drop-down menu in the right side of the bar of the pop-up dialog box "File name" edit box, enter the file name you want to use must enter the correct extension such "Text1.asm, then click the" Save "button. (Note: If you write programs in C language extension. "C"; If the program is written in assembly language, then the extension. "Asm", and must add the extension file name.) ② The return to the editing interface. Click the "Target 1" in front of "+" sign, then right-click on the "Source Group 1". Principles of  laser pointer  with remote control should be stated in the first place.
Pop-up as shown in Figure 4 as shown in the shortcut menu. Figure 4.4 and then click "Add File to Group'Source Group 1 '", open as shown below dialog box defaults to 19 in the "File Types" at the "C Source file (* c)", because we saved assembly language file, so the need to select "Asm the Source file (*. s *; * src; * a *), so that in the above you can see the assembly language file you just saved xianshi.asm, double-click the the file is automatically added to the project, click the "Close" to close the dialog box. ③ and then on the right side of the editor input assembler source. When entering commands, the reader can see in advance to save the file to be edit the benefits. The RF emitter of  laser pointer  with remote control is embedded with a wireless RF emitter.
Keil will automatically identify keywords, and prompts the user to the attention of a different color, this would allow the user to make fewer mistakes, and help to improve the programming efficiency. End of program input, do not forget to save again. ④ program files finished editing, click the "Project" menu, select "Built target" option (or use the shortcut key F7), or click the shortcut icon of the toolbar to compile, ⑤ If there are errors in the last all the error location and cause of the error will appear in the output window, and "Target not created" prompt.
