Assignment #8 Embedded Programming

Introduction

I wanted to learn c to program the board but I didn't have much time so I learned Arduino language and used it to program the board so the LED would work whenever some one press the push button

• I started by reading the Microcontroller data sheet, and learned the uses of each pin and how to connect the right



• also i started to compare between the Attiny 45 and 44 so I would choose between them probably



• I programed the board that I made in the 6th Week

• I used Arduino Language to program the board, but I had to Burn Bootloader first
• I searched for tutorials to help me and I found this one , so I followed the steps as it say by Open the preferences dialog in the Arduino software, find the “Additional Boards Manager URLs” field near the bottom of the dialog and pasting the following URL into the field:
  

  https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json 

• I opened the boards manager and searched for “ATtiny”





• I choose the ATtiny from board after I install it


• I choose the ATtiny 44 from the processor menu


• and put the clock on 20MHz


• Don't forget to adjust your programmer to be USBtinyISP



• You can learn more about programing with Arduino form here
• Take care to choose the right arduino pins in for ATtiny, this photo helped me alot in doing that



 int LED = 7;
 int BUTTON = 3;

 int STATE;

void setup() { 
pinMode(LED, OUTPUT); 
pinMode(BUTTON, INPUT); 
// put your setup codehere, to run once:

} 
void loop() { 
  // put your setup codehere, to run repeatedly:
STATE = digitalRead(BUTTON);

if (STATE == HIGH) 
{ 
  digitalWrite(LED, LOW);
} 
 else{ 
   digitalWrite(LED, HIGH); 
} 
}
