* Grouped UPM python modules into upm directory, for example: /usr/local/lib/python2.7/dist-packages/upm * Updated UPM example import statements * Removed unused RPATH statements from UPM src CMakeLists.txt, currently build collateral contains an explicit RPATH which is stripped from the install collateral. * Converted python examples to work on both python2 AND python3 * Added ctest for loading examples w/python3 * Removed returns from swig macros * UPM python module use will change... Before: import pyupm_dfrph After: from upm import pyupm_dfrph or import upm.pyupm_dfrph etc... * This commit fixes #468 Signed-off-by: Noel Eck <noel.eck@intel.com>

By default, this radio simply transmits data sent via writeData()
|
|
and reads any available data via readData().
|
|
|
|
It can be placed into a configuration mode by grounding the
|
|
CONFIG pin on the module. When this is done, the various
|
|
configuration query and config methods can be used. In this
|
|
example, by default, we just read any data available fom the
|
|
device, and periodically transmit "Hello World".
|
|
|
|
If any argument was specified on the command line, do a simple
|
|
configuration query and output the results. The radio must be in
|
|
CONFIG mode for this to work.
|
|
|
|
Note that the first command-line argument should be "hmtry.py"
|
|
The data we want would be the second... if it exists
