Arduino hx711 weight scale interface 1 0 software free. The output for communication is fed to the A0 and A1 analog inputs. The data needs to be ported to a PC by USB. Would the hx711.h libary need to be adapted or can I change the libaries name for example hx711-1 and hx711-2 and both use in the same sketch? Now would it be possible to have two of the HX711 connected to an UNO and read all the load cells to a serial print function. So the second HX711 connected to A2 and A3.

If I'd need to install ImageMagick. Found reference to a windows installer for PythonMagick on the wxPython wiki, but the links take me to procoders.net, which.

Installing PythonMagick on OS X • brew install boost - will take a lot of time and make your Mac hot • brew install --with-magick-plus-plus imagemagick • cd •./configure --with-boost= • make • make install • python -c 'import PythonMagick' If PythonMagick build fails saying that it couldn't find -lboost_python navigate to /lib/, ln -s libboost_python-mt.dylib libboost_python.dylib and run make again. Tested on 10.6.8 with Python 2.6.7 (custom build). Should work with Lion running stock 2.7. NOTE: Looks like I was too quick to call it done.

The module imports but raises exceptions when used. $ brew install --with-magick-plus-plus imagemagick $ brew install boost --with-python $ brew install boost-python $ cd ~/Downloads/PythonMagick-0.9.12 $ BOOST_ROOT=/usr/local/Cellar/boost/1.59.0/ $./configure Now you need to edit Makefile and pythonmagick_src/Makefile to include the boost library. You want to find two lines, one that starts with DEFAULT_INCLUDES and the other with LDFLAGS.

Add boost paths to the end of those lines so they look something like this: DEFAULT_INCLUDES = -I. -I$(top_builddir)/config -I/usr/local/Cellar/boost/1.59.0/include LDFLAGS = -L/usr/local/Cellar/boost-python/1.59.0/lib.

Make[1]: *** [libpymagick_la-_Image.lo] Error 1 make: *** [all-recursive] Error 1 Anyone getting these errors? Due to changes in the ImageMagick API for version 7 and later, as of PythonMagick-0.9.18 there are some broken hooks that will raise Symbol Not Found errors when attempting to import the dynamic library, and possibly a KeyError('cacheThreshold') when attempting to import PythonMagick. In addition to the above steps (using homebrew to install ImageMagick, boost, boost-python etc).

You may also need to apply the following changes. Here I have done a 'git diff' on my version (working on MacOS 10.12.6 with ImageMagick 7.0.5) against the current master branch as of late Dec 2017. Following above, you'll need to modify __init__.py to point to the correct functions as well. This version () seems to fix the above errors: I can do:./configure make make install on 10.13.6 (High Sierra), Python 2.7.15, resulting in output below. However, if I do python -c 'import PythonMagick', I get: Traceback (most recent call last): File ', line 1, in File 'PythonMagick/__init__.py', line 1, in from.
