The first LED (LED light-up process)

First contact with the microcontroller, my first experiment: let the microcontroller on the 4th led lit up.

Step one: Create a new Keil folder on the desktop

Step two: Open Keil uVision4,

Step three: Create a new project file

Step four: This will bring up the interface

Click on Atmel to select At89c51

Five: Click File->new and save to create a. c file

Six: Start compiling

Remember to save the file after compiling and click

Then click on output-"Create HEX file to tick T

Then execute the file.

Open the Stc-isp software, after debugging download programming, copy the code to the microcontroller effect such as:

That is, if you want to make other LED lights on the code can only change the program, but this should first understand the SCM schematic LED module, so as to succeed!
