Installing NXDRV-SPI-Driver on a Raspberry Pi

This installing guide provides the installation requirements.

Requirements

  • cmake
  • ccmake (optional)


Installing requirements

Install cmake

$ apt-get install cmake


Install ccmake (optional)

$ apt-get install cmake-curses-gui


Installing libcifx

Extract the sources from the zip-file.

$ tar xf <driver_version>.tar.gz


Change to the libcifx directory.

$ cd <driver_version>/driver/libcifx/


(Optional) Create a build directory.

pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx $ mkdir build && cd build
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $


Configure CMake environment with ccmake (optional).

pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ ccmake ..

Enable SPM_PLUGIN and DISABLE_PCI.


Press "c" to configure cmake and then "g" to generate make file.


Configure CMake environment without ccmake.

pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ cmake .. -DDISABLE_PCI=ON -DSPM_PLUGIN=ON


Build and install libcifx.

pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ make all
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/driver/libcifx/build $ make install

Compiling the example programs

Go to the examples folder.

pi@raspberrypi:~ $ cd V2.1.1.0/V2.1.1.0/examples/
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples $


Create a build directory.

pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples $ mkdir build && cd build
pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples/build $


Configure CMake environment

pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples/build $ cmake ..


Build all source modules

pi@raspberrypi:~/V2.1.1.0/V2.1.1.0/examples/build $ make all

Please do not forget to activate SPI interface on your Raspberry Pi!

Run Python script example

Download pycifx here.

Extract the sources from the zip-file and go in to pycifx.

pi@raspberrypi:~ $ cd pycifx/
pi@raspberrypi:~/pycifx $


run main.py

pi@raspberrypi:~/pycifx $ sudo python3 main.py

Issues during build process

While compiling cifxtcpserver example, this error appears.

Error: multiple definition of 'g_ptMutex'


Quick solution: In TCPServer.c located under <driver_version>examples/cifXTCPServer/, line 56 replace pthread_mutex_t* g_ptMutex to e.g static pthread_mutex_t* s_ptMutex and replace g_ptMutex to s_ptMutex.


Connect a netX90 based device to the Raspberry Pi 


netSHIELD90 and Raspberry Pi pinout


Make sure to configure your netx90 based device via netX Studio.


Run cifxspisample. You should get a similar output
