The first “Hello World!” project I prefer for Microcontroller is LED Blinking. I have used ATMEL’s 89C51 (40-pins DIP) 8051 architecture microcontroller which is ideal for first time learning MCU Chip. I used my previously made 5V Regulator to supply uninterrupted regulated DC voltage. The program is very simple and straight forward, that uses a delay procedure that loops for 255 x 256 = 65536 times and produce loop based software delay.
org 0000h loop: mov b, #0FFh acall delay clr p1.0 mov b, #0FFh acall delay mov p1, #0FFh ajmp loop delay: djnz acc, delay mov acc, #0FFh djnz b, delay ret end
goood project for learning
how do you connect the microcontroller with the pc.
hi.i interest about MCS-51.Your project LED Blinking by 8051 it very easy.
Thank you for example.maybe u have free time.
Thank You.
Good start!
goooooooooddd..
do you have an example to blinking 7 led sir?
i need a circuit and the source code also..
perhaps the source code is using keil uversion and 8051 microcontroller..
Hi there. I have a simple project for school. I need to connect a 8051 to a 7 segment lcd and to make a counter. Basically once every 2 seconds the display should increment with i(where i is a value that can be set from the assembly code). When it reaches 10 it should overflow and start over.
I need to simulate this in proteus.
Please help me. I will be forever grateful.
