Operating 6 led's independently

Hi Stan,

Yes this is a possibility. Make sure you get an AT 328 that has a bootloader installed or you will have to make another step and install it yourself. Of course you will have to provide power and a 16mHz crystal for the breadboarded  AT 328.

Thanks John.

I just ordered a pre-loaded chip from Adafruit.

Also found they have led strings that can be programed like what I have been trying to do for the last few weeks

with single lead's. LOL

The experience has been lots of frustration, but lots of fun!

I would still like to learn the extra step it takes to install the bootloader myself.

Just not today........

Thanks again John.

Hi Stanley,

Sounds good. Let me know as I had to do it once, accidently ordered blank AT328s, and I still have the procedure around here somewhere. Good luck on your project.

John

Hello John,

I'm still thinking about my first attempt at using a blank ATtiny861a.

I think my trouble started with all the how to, youtube videos on the subject.

Below is what I tried to burn to the 1Mhz 861tiny chip first, before knew about boot loaders. (I didn't write it.)

It didn't work so tried another one for 8Mhz. Then I tried the boot loader. Then I started over and went through it all again.

Would this render the 861 unusable.

attiny861at1.name=ATtiny861 @ 1 MHz  (internal oscillator; BOD disabled)

attiny861at1.upload.using=arduino:arduinoisp

attiny861at1.upload.maximum_size=8192

# Default clock (slowly rising power; long delay to clock; 1 MHz internal)

# Int. RC Osc. 8 MHz divided by 8; Start-up time PWRDWN/RESET: 6 CK/14 CK + 64 ms; [CKSEL=0010 SUT=10]; default value

# Brown-out detection disabled; [BODLEVEL=111]

attiny861at1.bootloader.low_fuses=0x62

attiny861at1.bootloader.high_fuses=0xDF

attiny861at1.bootloader.extended_fuses=0xFF

attiny861at1.bootloader.path=empty

attiny861at1.bootloader.file=empty861at8.hex

attiny861at1.build.mcu=attiny861

attiny861at1.build.f_cpu=1000000L

attiny861at1.build.core=tiny

attiny861at1.build.variant=tinyX61

Hi Stanley,

As long as you did not apply too much voltage to the Tiny or improper polarity it is unlikely that any damage was done to the chip. If it did not accept programming then more than likely something in the procedure was not correct. I personally have not used the Tiny so perhaps one of the excellent engineers on the site may help us out with a clear programming procedure.

The tiny I have been using recently was the one built into the Adafruit Trinket controller (5$ ish gets you the board) with USB boot loader, regulator the works and no special programmer required, very handy little board, you do need to have the riht software on the IDE though but that was a simple matter

this was the project : http://www.element14.com/community/groups/arduino/blog/2014/12/24/byob-party-6-introducing-baby-trinket-shhh-she-is-sleeping

sorry but I have yet to try programming my other ATMEGA85s directly

Hi Peter, You knew I was talking about you. Thanks for the input. At least there are some inexpensive solutions for Stanley.

John

John,

Finally have the  board soldered together and the lights working great.

Now just needs to be mounted on the quad.

I ended up using a mega328 preloaded with the boot loader.

I give up trying to use the tiny861. Probably going to throw them away.

Thanks to all of you for your help with this.

Stan
