Individual Assignment

Reading Datasheet

For our Fabacademy, I will be using the tinyAVR family. The Datasheet was 21 long pages so I skimmed and scanned through it to understand the basics.

ATtiny44

VCC: Power Supply
GND: Ground
Port B (PB3...PB0)4-bit bi-directional I/O port with internal pull-up resistors.
RESET: Reset input. A low level on this pin for longer than the minimum pulse length will generate a reset, even if the clock is not running.
Port A (PA7:PA0): a 8-bit bi-directional I/O port with internal pull-up resistors

The ATtiny 44 requires 1.8-5.5v power supply and its operational range is from -45 deg - 85 deg celsious.

Programming

For this week, we have to program our board (Echo-Hello-World) which made in the Electronic Design week using the Programmer (FabISP) which we made in the Electronic Production week.

First install Windows 10 driver here (USBtinyISP)

After that I connected the Fabisp to the Hello world board using the SPI cable. I followed the spi pinout diagram below to connect the FabISP to Echo Hello World.

Since, I have already programmed my Echo hello world using ISP in my week 6 Electronic Design, I followed the same steps.

First I set my board to ATtiny 24/44/84, then set the processor as ATtiny44 and then set mmy Programmer to USBtinyISP.

After that I went into examples and used the blink code. I changed my output pin to 8 and I uploaded it.And it was successfully uploaded.

Below is a video of the programmed board.
