Embedded Programming

Group assignment
- Compare the performance and development workflows for different microcontroller families
- Document your work (in a group or individually)
Individual assignment
- Read the datasheet for the microcontroller you are programming
- Program the board you have made to do something, with as many different programming languages and programming environments as possible.

Read the datasheet for the microcontroller

Before I do the programming, I needed to know more about MCU.

My board was using Atiny85 and I could check the data sheet here

First I checked the pinout of Atiny85.

checked Pinout and my board's Pinout connection.

I used RGB LED. The pinout was connected to PB0, PB1, and PB2, while the switch was connected to PB4.

Programming

I checked the Pinout connection and tried programming.

tried programming on the Aduino board using a scratch.

downloaded the S4A that can program the Aduino board and downloaded and installed the firmware to read the board.

I checked the operation of the board and simply programmed it.

Through programming, we could make LEDs that shine every second.
week8

Scratch was easy for beginners to use because the commands available were visible.

After simply using the scratch, I returned to Aduino and tried programming.

I connected the my board with the my laptop.

But my laptop could not read my board (Windows 7...) and I was able to try programming with Jeong Hwan's help.

I connected my board to MacBook and set up the tool and programming it. My ISP and RGB board worked well and I was able to light up the red light every second by programming.

TEST Programming

I wanted to use RGB LEDs to make more color, but I was not able to make progress because I was not good at programming, but with Craig's help, I was able to complete programming.

Functionality is set so that RGB LED and switch are available.

The use of PinMode has been made so that LEDs.

Finally, the random function was used to make the random light

Random LED Programming

Programming is too difficult and there are many things to know...

My random led color code

int ledR = 0;
int ledG = 2;
int ledB = 1;
int swPin = 4;

byte number;

#include 

SoftwareSerial mySerial(2, 3); // RX, TX


void setup() {

  pinMode (ledR,OUTPUT);
  pinMode (ledG,OUTPUT);
  pinMode (ledB,OUTPUT);
  pinMode (swPin,INPUT_PULLUP);

  mySerial.begin(4800);


}

void loop() {


 mySerial.println(number);

 boolean push = digitalRead(swPin);
 if(push == true){
     // give me a number between 0 - 5 (inclusive)
number = random (0, 6);
 }

if (number == 0) {
  digitalWrite(ledB, HIGH);
  digitalWrite(ledR, LOW);
  digitalWrite(ledG, HIGH);
  delay (100); }

if (number == 1)  {
  digitalWrite(ledR, HIGH);
  digitalWrite(ledB, LOW);
  digitalWrite(ledG, HIGH);
  delay (100); }

if (number == 2)  {
  digitalWrite(ledB, HIGH);
  digitalWrite(ledG, LOW);
  digitalWrite(ledR, HIGH);
  delay (100); }

if (number == 3) {
  digitalWrite(ledG, LOW);
  digitalWrite(ledR, LOW);
  digitalWrite(ledB, HIGH);
  delay (100); }

if (number == 4) {
  digitalWrite(ledR, HIGH);
  digitalWrite(ledG, LOW);
  digitalWrite(ledB, LOW);
  delay (100); }

if (number == 5) {
  digitalWrite(ledR, LOW);
  digitalWrite(ledB, LOW);
  digitalWrite(ledG, HIGH);
  delay (100); }
