Hi I am aashish, I am a pure beginner to 8051 microcontrollers and want to Blink a LED with it (as my first test).
But at the end the LED did not blink , I performed the following steps,
1. Generate Hex file from keil uVision
2. Flash the AT89S52 with this hex file using a 8051 programmer.
3. Connect a LED to AT89S52 on breadboard to test my work.
Please have a look at the word document : https://drive.google.com/file/d/0B5NYQC3oiHcHcjh2a3RBOW5famc/edit?usp=sharing to see the detailed steps that I have followed along with the connection of LED to AT89S52 on breadboard to test my work
So where I was wrong? my program is incorrect/incomplete?? Or Does the AT89S52 not have an on chip clock? Whether I have to connect an external crystal?? Or anything I am missing .??
Please help me I am in a great need of it. Please help.
Thanks in advance.
