Week 7: embedded programming
COMPLEATED
It's time to use our FabISP programmer. I have installed Arduino software and also installed Attiny drivers in it.
Attiny library you can find here: https://github.com/damellis/attiny/
To install library:
- Create a new folder "hardware" in the Arduino sketchbook folder.
- Copy the attiny folder from inside the .zip to the hardware folder.
- Restart the Arduino software
- You should see ATtiny entries in the Tools > Board menu.
Our helloBoard using Attiny44 with external 20MHz sourse.
So before programming i chosen:
Board:Attiny
Clock: 20MHz
Prcs: ATtiny44
Using a standart scatch and changing pin numbers i programmed my HelloWorld board.
The result you can see on the video:
So, it works and now i can play with my own code. My first attemp was to use fade effect.
Here is my code:
const int buttonPin = 3; // the number of the pushbutton pin
const int ledPin = 7; // the number of the LED pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
int brightness = 0;
int fadeAmount = 5;
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}
void loop() {
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == LOW) {
// turn LED on:
// set the brightness of pin 9:
analogWrite(ledPin, brightness);
// change the brightness for next time through the loop:
brightness = brightness + fadeAmount;
// reverse the direction of the fading at the ends of the fade:
if (brightness == 0 || brightness == 255) {
fadeAmount = -fadeAmount ;
}
// wait for 30 milliseconds to see the dimming effect
delay(30);
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
}
}
Next attemt was to program SOS signal. It looks like:
Here is my code:
const int buttonPin = 3; // the number of the pushbutton pin
const int ledPin = 7; // the number of the LED pin
// variables will change:
int buttonState = 0; // variable for reading the pushbutton status
int k = 0;
void setup() {
// initialize the LED pin as an output:
pinMode(ledPin, OUTPUT);
// initialize the pushbutton pin as an input:
pinMode(buttonPin, INPUT);
}
void loop() {
// read the state of the pushbutton value:
buttonState = digitalRead(buttonPin);
// check if the pushbutton is pressed.
// if it is, the buttonState is HIGH:
if (buttonState == LOW) {
k = 1;
if (k == 1) {
delay(1000);
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
delay(100);
digitalWrite(ledPin, LOW);
k = 0;
}
}
else {
// turn LED off:
digitalWrite(ledPin, LOW);
}
}
