I've tried antthing i've found on all forums... all connections are ok, all settings... Arduino as Isp.. etc
I keep getting this error :
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x03
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x03
....
vrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x03
I'm done with it, for 10 hours i keep searching until i've decided to write a topic...
Which tiny85 bootloader is this? Which core are you using? Where is a schematic of your connections?
The ATTiny85 isn't normally used with a serial bootloader (as it doesn't have hardware serial, making the bootloader larger and slower, and it is usually used without an external crystal - but the internal oscillator isn't accurate enough for serial to work without tuning)
I did put a 10uf capacitor and i've tried also with 100uf and 150~ i guess, nothing worked.
I don't understand why, i've tried with 2 separately attinys, nothing.
Connections and Uno are both OK the voltage is ok,
In Device Manager I got Port 3 (uno) all recognised, all works fine but I don't understan that error
spycatcher2k:
I did not ask you to tell us where you found it on the internet!
One more chance.
Sorry, so exactly as on that website
Attiny pins 1 to UNO pin 10
Attiny pins 2,3 not conected
Attiny pins 4 to UNO pin GND
Attiny pins 5 to UNO pin 11
Attiny pins 6 to UNO pin 12
Attiny pins 7 to UNO pin 13
Attiny pins 8 to UNO pin VCC (5v)
And what were you attempting to do when you got those errors? "Burn Bootloader" I assume?
Those errors, when programming a device over ISP using an Arduino running Arduino as ISP sketch indicate a failure to communicate with the Arduino as ISP sketch on the Arduino you're using as a programmer.
Was the Arduino as ISP sketch successfully uploaded to the arduino being used as the programmer? Is there a 10uF capacitor between reset on the Arduino being used as the programmer and ground?
Also - this isn't your problem yet (the problems this can cause are further into the process) but did you connect a 0.1uf capacitor between Vcc and Gnd, right next to the attiny85? You always need a 0.1uF cap between supply and ground on digital IC's, including microcontrollers, and many tutorials omit this necessary component; without it, you may experience random resets, hangs, or failure to program.
I WAS FULL OF RESPECT! I DIDN'T WANTED TO OFFEND YOU!
CrossRoads:
"ARDUINO -> PC via printer Cable "
Really? How old of a PC do you have that it still has a printer connection?
What are you using to adapt it to USB to plug into the Arduino?
An printer cable... this is how it's 'old' name is...
I think i made a big mistake writing here, showing all 'pros' here just comments like thei are superman/ hackerman, don't tell me you wasn't a beginner at first.
spycatcher2k:
Nope - That is a USB A-B cable, used by Printers, Scanners, and a multitude of devices. A Printer cable is a specific cable, nothing to do with arduino, but could be used with a home built programmer.
Attention to detail (or lack their-off) is probably what the issue is.
Lets try AGAIN - post a close up, in focus picture of your wiring, and a snapshot of your desktop with your mouse on what you click to produce the error.
