- Week 07: Embedded Programming -

Weekly Assignment

• read a microcontroller data sheet
• program your board to do something, with as many different programming languages
• and programming environments as possible

0: Read a data sheet

As start of this week, I check a data sheet of Atmel processor.

1: Installing hardware support

I installed ATtiny support file according to “High-low tech” site.
I am using Arduino IDE 1.6.1. I downloaded the “For Arduino 1.6: ide-1.6.x.zip”, as I moved the directory to "~/ Document/ Arduino"

It is necessary to change the folder name. "attiny-ide-1.6.x" to "hardware"

After rebooting the software, it apply to change.

2: Setting hardware configuration

I set the hardware configuration.
I clicked tool tab, and choose

Board> ATtiny

Clock> 20Mhz

Processor> ATtiny44

Port> Serial ports

I burn boot loader by AVRISP mk2, because my FabISP does not operate smoothly.
I set programmer.

Programmer> AVRISP mk2

After setting, I burned boot loader.

3: Coding and writing

I wrote a code by C. I modify the code based on the arduino sample.
After then, I check the code. I Clicked compile. If it has problem, the app return a error.

As I succeeded compile, I burned the code to the machine.

5: Check behavior

					void setup() {
		     			pinMode(3,INPUT) ;   
		     			pinMode(7,OUTPUT) ; 
					}

					void loop() {
		     			if (digitalRead(3) == HIGH) {    
		          			digitalWrite(7,LOW) ;     
		     			} else {
		          			digitalWrite(7,HIGH) ;  
		     			}
					}

					int inPin=0;//input number
					int outPin=13;//output number
					int pinData=1;//swich syokijyoutai 
					boolean led=false; 

					void setup() {
						Serial.begin(9600);
		 				pinMode (inPin,INPUT);
		 				pinMode (outPin,OUTPUT);
					}

					void loop() {
						Serial.println (pinData);
		 				if (digitalRead(inPin)==HIGH){
		      				pinData*=-1;
		    			}else{
		    				pinData*=0;
		    			}
		    			if (pinData==1){
		      				(led=true);
		    			}
		    			else{
		      				(led=false);
		    			}
		  				if(led==true){
		     				digitalWrite(outPin,LOW);
		    			}else{
		    				digitalWrite(outPin,HIGH);
		    			}
		    			delay(200);
					}
