Introduction: How to Program Attiny85/45 With Parallel Port?
Hi all! Today i'm gonna show... blah blah blah xD
6(reccomended) or 10 ribbon cable
Power source (Needed for programming, since power can't be obtained from LPT)
NB! If voltage is over 5v, you need voltage regulator or other power source
4 470 ohm resistors
breadboard (not on the picture)
100 ohm resistor
Step 1: Making Programmer
Look at the pictures, i did wrote stuff to there :3
Step 2: Programming
Now connect it to your computer
I know only one method how to program ATtiny85 with LPT:
- Linux and avrdude(and tools)
If you know how to do it in Windows, Please tell me!!!
Now if you're connecter your programmer cable, connect it as the 2nd picture shows
NB! MISO and MOSI must be swapped(like on the picture)
Step 3: Open Your Terminal
Since only root can acces /dev/parport0, then you need to use su(do)
If you can't, then ask your system administrator
So open up your terminal, and type:
$ sudo avrdude -p t85 -P /dev/parport0 -c bsd
$ su -c "avrdude -p t85 -P /dev/parport0 -c bsd"
* bsd means the type of tis programmer
* t85 means attiny85
If there is no errors, THEN IT'S VERY GOOD! :)
It is??? Check cables or remove resistors, maybe you soldered wrong(like i did before :D)
Step 4: AND Your First Testprogram!
Link to the program: http://db.tt/j55e2lkz
NB! just run "make", sudo stuff are in the makefile
If you connect it so(like on picture), it should start blinking
