Assignment

Read a microcontroller data sheet and program an ATtiny board in different Embedded programming techniques is used.

For the programming purpose I already done a board in my week6 assignment, and I check it once again the board is working or not; it’s fine.Here is my board

Reading Data Sheet

The whole data sheet is repeating the pin configuration when we are programming the microcontroller we must keep the pin configuration. Otherwise, we can not get the out. I am all ready to explain the detail of microcontroller data sheet in week6.

pin configuration of ATtiny44

What is programming or burning a microcontroller?

programming or burning a microcontroller means to transfer the program from a compiler to microcontroller the program of a microcontroller is generally written c or assembling language finally the compiler generate a hex file which contains the machine language instruction understandable by a microcontroller.

How to program a microcontroller

For the programming, we need A programmer is a hardware device with dedicated software which reads the content of the hex file stored on the PC or the laptop and transfers it to the microcontroller to be burned. I am already done the programmer in week4

how to conect the programmer and a microcontroller?

In here six pin isp cable is used to connected the microcontroller and programmer

pin structure of 6 pin isp

then I start to the program

program the board

For the programming First, i download the Arduino IDE. For the programming ATtiny, we want to add the ATtiny board manager for that I referred this instructions,and it added successfully

In here ATtiny44 is used in the hello board for that I am select

tools->board->ATtiny

tools->processor->ATtiny44

tools->clock->20mhz(external)

tools->programmer->USBtinyISB

In here I am connecting two led and a switch into the ATtiny44, for the programming purpose we want to understand in where we connected the led and switch pin into the attiy44, for that I have referred the schematic diagram.

when I programming Arduino I am so confused where I am connected the led to the Attiny44 pin,I am programmed in my schematic diagram pin wase, but I did not get the out, then I refer the pin diagram of ATiny44 I have to understand where I do the mistake.
