Issues with ATtiny85

[drtrigon]

I was able to come quite far but get got stuck with this: "make[1]: *** [device/try1/onewire.o] Error 1"

Here is my "project.cfg":

_include: world.cfg
env:
  prog: avrisp
devices:
  _default:
    _ref: defaults.target.t85
    types:
      _ref: defaults.types
    code: []
  try1:
    _doc: My very first 1wire slave device
    defs:
      is_onewire: ds2423
    onewire_id: x49ae6a524a39
targets:
- try1

I had to modify the "Makefile" as well:

$(AVRDUDE) -c $(PROG) -p $(MCU_PROG) -C +$$TF\

needed to be changed to

$(AVRDUDE) -c $(PROG) -p t85 -b 19200 -P /dev/ttyACM0 -C +$$TF\

as I could not figure out how to do this in "project.cfg". (See also [1].)

[1] http://technostuff.blogspot.ch/2013/06/arduino-nano-v30-with-avr-dude.html

With all this I get an error during the first step of make:

What can I do now? What am I doing wrong?

[drtrigon]

It seems that I have to modify the owslave source code as mentioned in #13, correct?

[pklarsjo]

Hi,

I have the exact same problem. Did you find any solution to this?

[drtrigon]

As this code supports mostly (only) mega8 which is kind of uncommon - at least for me - I changed to https://github.com/orgua/OneWireHub which is a library that can be used with Arduino IDE in a sketch (in other words with a bootloader) and supports a wide range of hardware like Uno/Nano, ATtiny, etc.

[drtrigon]

Forgot to add; OneWireHub has the further advantage that it emulates standard devices that are supported by most master out of the box.
