(ATMEGA 16) USART

Let us go through presentation

When you make communication with computer you would need Max232 IC which is voltage translator. You can find its schematic online. As it is one of the most popular form of communication there are plenty of resources on this online.
You can search for schematic in google images and i bet it would be the first pic.


You can find the code here

(P89v51RD2) UART

Serial Communication is one of the essential component of embedded design. I am going to explain RS232 communication using this controller.
Let us go through the presentation which explains the register to configure
Look for PORT 3 Pin configuration PIN named RX & TX are used for Serial communication

(Atmega 16) 20x4 LCD

20x4 LCD is extended version of 16x2 LCD the only difference is their size & capacity to display
16x2 is 16 character x 2 lines &
20x4 is 16 character x 4 lines
Their interfacing is same. Please refer the bottom memory diagram for 20x4 in the slide which is same for 16x2

Please find controller specific details & compiler details on that specific page.

(Atmega 16) 7 segment

Let us have the presentation first

Now we have 8 7-segment display.
How many microcontroller pins are required to interface it.
You might me thinking it would be 8x7=56. Microcontroller don't even have that many I/O.
So we would go ahead for multiplexing which would utilize just 16 I/O lines

Refer to schematic below

Now i have 2 codes for this that explain different cases when you work on it

You can see all compiler details on page Atmel AVR page

(Atmel Atmega16) Blink LED!!!

When you work on AVR I/O ports you have to take care of 3 register

1)DDR:- to set the direction (either input or output)

2)PORT: write your output data to PORT

3)PIN: Read your data input from PIN
