Programming Attiny2313 with Arduino Uno The 2313 processor is a 20 pin chip with 17 I/O pins, it do not have a ADC (analog/digital converter) It can be configured to run at 1 MHz and 8 MHz without External Crystal/Resonator 2313 pinout Connection to Arduino Download the Tiny-core here: Follow the instructions in the Connect your Arduino to the Attiny according to the picture to the right connection to Arduino: Arduino Attiny2313 13 19 PB7/SCK 12 18 PB6/MISO 11 17 PB5/MOSI 10 1 PA2/Reset 5v 20 VCC GND 10 GND • Upload the ArduinoISP to the Arduino dont't connect the capacitor yet. • Note: the ArduinoISP has some issues in ver. 1.00 • Connect a 10 µF capacitor from reset to ground on the arduino (negative side to ground) If you are using a Duemilanove use a 120 ohm resistor from reset to Vcc • Open the blink sketch from the examples->Basic->Blink • Select Attiny2313: Tools->Board-> Attiny2313@1MHZ • Select ArduinoISP: Tools->Programmer->Arduino as ISP • Upload your sketch: Select File->Upload using programmer • Connect a LED with resitor to pin PB4 (physical pin 16) • Now you should have a blinkining Led on your Attiny 2313 Note the factory default is 1MHz, if you want to run it @ 8MHz, use: burn bootloader.

Worry no more, with this tutorial you will learn how to use an Arduino Uno as an AVR. Want a cheap solution, or even a spare solution for AVR programming? Avrdude.exe: Expected signature for AT90S2313 is 1E 91 01.

Select board -> Attiny2313@8MHZ Select ->Tools->Programmer->Arduino as ISP select ->Tools->Burn Bootloader Note: this step do not burn a bootloader to your chip, it is only used to set the fuses to another clock-speed. When you use it in your project, it will be a good idea to connect A 0.1 uF across VCC and GND as close to the processor as possible, and a 10 K ohm resistor from RESET to VCC. Communication with Attiny2313 It is always nice to be able to get debug information from your tiny. On an Arduino you are used to use Serial.print() for this purpose. Luckily you can use this on Attiny as well. Actually you have more options: TinyDebugSerial - comes with the core files (only output from attiny) SoftwareSerial - use the SoftwareSerial library (Input/output attiny) TinyKnockbang - use TinyISP(only output fram attiny) RELAY_SERIAL - use TinyISP(Input/output attiny) A more detailed explanation: A solution for the missing ADC Atmel has some application notes on how to make a cheap ADC, using the comparator On the Attiny2313. For example: Sadly they don't provide any programming examples.

But I recently found an easy solution The sketch in the buttom of this page use a digitalRead() to measure the time in a rc-network. In the example they use a photoresistor, but you can substitute this with a potentiometer. I tried it With a 10 kOhm potmeter and a 0.1uF capacitor, which gave me readings between 0 and 600 In the sketch PIN 2, is PD2 on Attiny2313 - physically pin #4 Physical/logical pin numbers.

Does anyone know of any good websites where one can look up the date of a firearm's manufacture by its serial number? Taurus revolver serial number lookup. (I did try the search function on here to see if this has been discussed before, but I didn't find it; of course, I am old and barely computer literate, so I might have done it wrong!) There used to be a real good site put up by the 'Hoosier Gun Club', with a lot of links to sites where dates could be looked up by serial number, but it is not there anymore.

Since we will be using the Arduino Uno as an ISP programmer, we first have to upload a sketch that will be responsible for receiving data through the serial port (USART) and outputting it correctly to the target microcontroller through their SPI ports. So, open up the Arduino IDE, go to File>Examples>ArduinoISP. Once the sketch is open, on the top of the file, some comments are made on pin names and connections. Those will be addressed on the next step, but make sure they match with the tutorial.

Connect your arduino and fire the Upload button away. It takes a little more tha usual but don't worry. For this first step you will need the following materials: • Jumper wires of saveral colors (yes they matter);• 01 RED LED• 01 YELLOW LED• 02 LEDs of different colors, your choice (we are using blue and white)• 01 10uF electrolytic capacitor• 04 200 ohm 1/8W resistors These other materials are project-dependent.

In our case, we are going for a solution that uses a 8 MHz crystal and an internal clock with the same value. Therefore: • 01 8 MHz crystal• 02 20 pF ceramic capacitors Hook all the components together according to the picture. Do notice that for each trail that receives one of the lead of the crystal, there is a ceramic capacitor connecting this trail to the ground trail. The LEDs' anodes are identified by the slight curve their leads have. Pay attention to the white LED, the one to be blinked by the code that will be loaded. Due to a software limitation, that doesn't allow component flipping, the LED ended up being crossed.

The electrolytic capacitor is polarized, therefore make sure you have the longer lead connected to RESET while the smaller one is connected to GND. This will filter out the automatic reset signal, disabling it. A good advice is to keep the jumper wires in the same color code as the one shown in the picture. This helps further hardware debugging. Since you have used the Arduino IDE to load the ArduinoISP sketch to your Arduino board, this means that you already have AVRDUDE installed in your computer.
