After setting up starter 8051 board, we will start with simple LED blinking experiment. On this board 4 LED's are connected to higher four bits of PORT 3. We will write the code in Keil Compiler, to setting up Keil compiler for 8051 refer the 8051 Keil Setup tutorial. After generating the hex file refer the tutorial to uploading hex file using nuvoTon.
