Fab Academy 2016 Week08

read a microcontroller Data sheet

program your board to do something, with as many different programming languages

and programming environments as possible

First time, I checkd the piouts of all.

But I could not understand them.

So I thought that it is better to leran from block diagram.

I could understand the allocation of logical for the Attiny44.

But I need to learn more about the ATtiny and ATmega.

Because I make the flight controler for my final project.

I continue to learn the Attiny

I learned the SPI about MOSI,MISO,SCK.

These are connected to PC.

Hello.ISP board is connected to PC for data writing.

Hello-world board got the power from PC.

but this Hello-world board did not work.

therefore I checked the circuit. "+" and "-" were shoted.

I tried to repaire circuit. but could not it.

Then I made the Hello-world board again.

This circuit is not connect with "+" and "-".

I stored Hello.ftdi.44.echo.c. to new one.

It was successed to do.

However I could not understand C langage.

I proceed to learn it.

This board is new one.

It is not shoted with "+" and "-".

First time, I install Neil's Cfile.

It could be installed to circuit!

This circuit have LED(PA7) and Button(PA3).

I add below line to Neil's file.

---------------------------

#define led_port PORTA

#define led_direction DDRA

#define led_pin (1 << PA7)

---------------------------

void blink() {

static int i;

i = 0;

while(i < 10) {

set(led_port, led_pin);

led_delay();

clear(led_port, led_pin);

led_delay();

i++;

---------------------------

blink();

---------------------------

But this file is not work....

I am lerning the C now.
