Final Project
ASSIGNMENT
Attiny44 can be programmed in various ways and one of them is Useing ARDuin IDE and ARduino UNO
This is the Easiest Way to accompanist the task given basic understanding of what we are trying to do.
The first assignment in this week was to read a datasheet of a micro-controller and put up the findings from the same.
For this exercise we were given a Datasheet by class website.
Some Basics Before We move forward.
Above is the PINMAP of attiny44/48
Following are the important Information That will help us move to next step.
Following are the important References that got me running.
I have use arduino uno as programmer.
To make Arduino behave as ISP Load the Following code and burn it. as shown in the screnshot below
Examples>>ArduinoISP>>ArduinoISP
As we are using older version of Arduinos we need to uncomment line 81 to use:
Pin 11 :MOSI
Pin 12 : MOSI
Pin 13: SCK
Pin 10: RESET
Note this has to be done before connecting arduino to the Attiny board.
Lets Get started With Programming The Board.
Following are the Screen-shots of how I dit it.
Setting up the Arduin IDE
Arduino IDE can Program boards with ATtiny family controllers but we need to provide the definitions of board for the same to Arduino.
To Do so Press Crol+, (comma) or go to preferences from File menu.
and the below Dialog box will appear.
In the Additional Boards Manager URLs: Pase the below link to the json file which has the address for all board definitions.
https://raw.githubusercontent.com/damellis/attiny/ide-1.6.x-boards-manager/package_damellis_attiny_index.json
This Will tell Arduino IDE where to look for board files over the Internet.
Go ahead and install the same.
this might take a while.
This is a one time process for working with ATtiny boards anytime in future.
Now go to Tools >> Board : >> Attiny 24/44/84
Next I select clock" as External 20Mhz
( we dont need this but i tried this first to see what it does)
Now we can see the Tttiny board is available under the boards list
Select Processor as ATtiny44.
Next I loaded the basic blink program form the examples in Arduino IDe
As we can see below Our LED pin is connected to PA7 or say pin 6 on the ATtiny44
We use pin 7 to referrer form arduino code
So the default Blink code we change 13 to 7
Now connect using jumper wires as follows
Reset >> pin 10 on ardunino
VCC >> 5v on arduino
GND >> ON arduino
MOSI >> PIN 11
MISO >> PIN 12
SCK >> PIN 13
The same is given in the arduino as ISP code if we scroll down.
The Joy of making it work !!
Thats me at my new Work place
Its a Maker Space Inside School In
Delhi.
