Step 1: How to Program Attiny2313
First of all, Attiny2313 is a 8-bit low range microcontroller from Atmel. It's a 20-pin IC (DIP, through hole package).
It have internal rc oscillator that supports frequency 1 MHz, 2 MHz, 4 MHz and 8 MHz
List of components:
- Attiny 2313 with ic base
- Male header
- Female-female jumper wire
- USBasp programmer
- AVRStudio (any version, I am using version 4)
- USB cable type-B
First of all, make development board for attiny2313 as given in the figure.
Step 2: Connections
Make connections as follows:
GND ========> GND (Pin no. 10)
VCC ========> VCC (Pin no. 20)
RST ========> RST (Pin no. 1)
MISO ========> MISO (Pin no. 15)
MOSI ========> MOSI (Pin no. 14)
SCK ========> SCK (Pin no. 16)
Once the connection is done, connect USBasp programmer to laptop/ PC. Open avrdudes, and follow the steps and given in the picture.
Open avrstudio, and copy the code in the editor. Compile the hex file and upload it using avrdudes.
Step 3: Final Connection
Add led array to the attiny 2313 development board. Cathode of all the led's are common and is connected to the ground of the development board.
A series resistor of 220 ohms is connected for limiting the current.
Leds are connected to portb.
