all the questions i saw regarding attiny's addressed operating issues. nobody but me seems to not be able to get it to work at all.
my arduino 1.0.1 works fine with my computer serial link, using arduino uno as the board. the example blink sketch blinks fine, as do other little programs i have written.
but when i try to program my attiny85 to do anything, it doesn't work.
i followed 3 or 4 sets of web instructions, including the youtube shrinkify video, but no luck.
here is what i have been doing, with comments.
a little help getting me going would be much appreciated.
1-plug in my uno board to the usb.
2- open the arduino p.env.
3- open example, arduino ISP
4- select board: arduino uno
5- upload arduino ISP sketch to the UNO board. loads without any issues.
6- close arduino ISP sketch. usb is still plugged in.
7- wire attiny85 per "shrinkify video" attiny 1:Uno 10 ; att 4:U grd ; att 5:U 11 ; att 6: U 12 ; att 7: U 13 ; att 8: U +5v; 10 microf cap reset to grd (neg side cap to grd). the usb is still plugged in.
8- open example blink sketch.
9- in sketch change pin 13 to pin 3.
10- select board : "attiny 85 (internal 20 Mhz clock)". the option shown in the video "attiny85 w/ arduino as ISP" is not available. in the lower right it says "ATtiny85(internal 8 MHz clock) on com3".
11- upload sketch. get error "avrdude: usbdev_open() : did not find any USB device "usb"".
if i plug in an led from atttiny pin 3 to ground, nothing.
i don't think it is working. i haven't fried my arduino, because if i dis-connect the attiny and the cap, and select arduino UNO board, it still runs the blink program just fine.
