Testing PCsensor's TEMPerHUM Part 4 - Linux (Software Logging)
Testing PCsensor's “TEMPerHUM”
Phase 4: Testing PCsensor's “TEMPerHUM” in Linux environment
In Phase 3 we talked about using TEMPerHUM temperature & humidity sensor in Linux GUI (graphical user interface)(graphical user interface). Now for those of you who prefer Linux CLI (command line interface), it would be needed to produce (or as it is said in Linux terminology, to make) an appropriate executable file by yourself because Pcsensor company did not want (or planned) to offer any Linux equivalent for TEMPerHUM software for Windows. Solutions that we found on the web were based on various source code packages provided by individual programmers, and it was expected that the end-users would produce the program executables on their own machines. So let us start with that funny game:
Please note that we used again Linux Debian 7.11 (“Wheezy”), as we did in our previous Linux tests. In addition, we compiled the same program packages on different computer hardware (a desktop and a laptop) because of possible variations in operating system capabilities regarding different CPU type & speed, the amount of RAM memory, etc. (However, if it is not specified in a particular paragraph, only a desktop installation is described.)
1. Usb-thermometer (https://github.com/petechap/usb-thermometer)
Desktop installation: Compiling usb-thermometer was successful but as seen bellow useless. According to the instructions, you need to have libusb-dev software package already installed on your computer. My Debian 9.11 desktop installation did not have libusb-dev so I installed it from Debian software repository:
root@localhost:/usr/local/src/usb-thermometer-master# apt-get install libusb-dev Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: Use 'apt-get autoremove' to remove them. The following NEW packages will be installed: libusb-dev 0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded. Need to get 40.8 kB of archives. After this operation, 239 kB of additional disk space will be used. Get:1 http://ftp.us.debian.org/debian/ wheezy/main libusb-dev i386 2:0.1.12-20+nmu1 [40.8 kB] Fetched 40.8 kB in 1min 48s (375 B/s) Selecting previously unselected package libusb-dev. (Reading database ... 319934 files and directories currently installed.) Unpacking libusb-dev (from .../libusb-dev_2%3a0.1.12-20+nmu1_i386.deb) ... Processing triggers for man-db ... Setting up libusb-dev (2:0.1.12-20+nmu1) ... root@localhost:/usr/local/src/usb-thermometer-master#
After installing libusb-dev, I executed make command:
root@localhost:/usr/local/src/usb-thermometer-master# make cc -DUNIT_TEST -o pcsensor pcsensor.c -lusb root@localhost:/usr/local/src/usb-thermometer-master# ./pcsensor Couldn't find the USB device, Exiting root@localhost:/usr/local/src/usb-thermometer-master#
Unfortunately, as shown in the last few lines above, the newly-built pcsensor executable did not return anything but an error message because it obviously expected the attached sensor hardware to be of the 'regular' USB type, which was not the case here (because this version of TEMPerHUM sensor was of so-called HID type, which meant it did not appear as a real USB device in Linux at all).
Laptop installation: Compiling usb-thermometer software package was successful but useless again. Before starting the compiling itself I ensured that my Debian 9.11 laptop installation was equipped with required libusb-dev software package: I used the APTonCD utility (installation disc creator for APT-cached packages) to transfer programs downloaded to the desktop machine (to avoid downloading them again over my slow dial-up access to the Internet).
root@localhost:/usr/local/src/usb-thermometer-master# make cc -DUNIT_TEST -o pcsensor pcsensor.c -lusb root@localhost:/usr/local/src/usb-thermometer-master# ./pcsensor Couldn't find the USB device, Exiting root@localhost:/usr/local/src/usb-thermometer-master#
As shown above, the sensor did not provide any output because the software expected the device to be a 'real' USB device while it was of the HID type.
2. TEMPered (https://github.com/edorfaus/TEMPered)
Desktop and laptop installation: To compile this software there were two prerequisites: HIDAPI library and CMake build system. The author of TEMPered had suggested to build HIDAPI library from sources on GitHub: https://github.com/signal11/hidapi so I did so. (See the next paragraph.)
2.1. HIDAPI (https://github.com/signal11/hidapi)
On its side, the HIDAPI author had suggested that for building his library it was needed to install development packages libudev, libusb and optionally Fox-toolkit (for the test GUI). On Debian/Ubuntu systems these packages can be installed by running:
sudo apt-get install libudev-dev libusb-1.0-0-dev libfox-1.6-dev
(On my Debian 7.11 desktop installation, that step required to download some 4.2 MB of material from Debian repositories, which also included some extra files not listed in the above apt-get install command. On my slow dial-up connectivity it took some 20min 13s. Note: I already had all of the above installed on my Debian 7.11 laptop installation, so the next step was skipped on the laptop.)

2.2. CMAKE
Desktop installation: For installing CMAKE, I used Synaptic Package Manager that besides cmake itself added cmake-data and emacsen-common, alltogether circa 6.2 MB to download. It took some additional 25 min or so to get those packages over my slow dial-up line. (By the way, for that task I could have also used my Debian 7.11 laptop, which I usually use for downloading anything bigger than 1 MB, and much faster by my university's Wi-Fi access, and what I later copy to the slow desktop computer with slow dial-up at home, but that particular day it was very rainy so I did not want to go outside and burden myself by getting wet in the academic campus.)
Laptop installation: I have already had all CMAKE stuff on the laptop. (In fact, I used all three CMAKE packages downloaded to the desktop above as the 'source-files' for the laptop's Synaptic Package Manager, so that I would not need to download them twice.)
The HIDAPI author has suggested that those users who had downloaded a source package from the website manually (i.e. if they did not run git clone), they can can skip the ./bootstrap step and go directly to the ./configure step. However that possibility did not work here properly:
root@localhost:/usr/local/src/hidapi-master# ./configure --enable-testgui --prefix=/usr/local bash: ./configure: No such file or directory
… so I performed ./bootstrap at first:
root@localhost:/usr/local/src/hidapi-master# ./bootstrap + autoreconf --install --verbose --force autoreconf: Entering directory `.' autoreconf: configure.ac: not using Gettext autoreconf: running: aclocal --force -I m4 autoreconf: configure.ac: tracing autoreconf: running: libtoolize --copy --force libtoolize: putting auxiliary files in `.'. libtoolize: copying file `./ltmain.sh' libtoolize: putting macros in AC_CONFIG_MACRO_DIR, `m4'. libtoolize: copying file `m4/libtool.m4' libtoolize: copying file `m4/ltoptions.m4' libtoolize: copying file `m4/ltsugar.m4' libtoolize: copying file `m4/ltversion.m4' libtoolize: copying file `m4/lt~obsolete.m4' autoreconf: running: /usr/bin/autoconf --force autoreconf: running: /usr/bin/autoheader --force autoreconf: running: automake --add-missing --copy --force-missing configure.ac:25: installing `./ar-lib' configure.ac:26: installing `./config.guess' configure.ac:26: installing `./config.sub' configure.ac:22: installing `./install-sh' configure.ac:22: installing `./missing' hidtest/Makefile.am: installing `./depcomp' autoreconf: Leaving directory `.' root@localhost:/usr/local/src/hidapi-master#

… no complaints there too ...

(The above two actions produced hidtest-hidraw executable.)

(The above three steps produced testgui executable.)
… now I wanted to perform some tests with HIDAPI software:
root@localhost:/usr/local/src/hidapi-master/hidtest# ./hidtest-hidraw Device Found type: 0c45 7402 path: /dev/hidraw0 serial_number: Manufacturer: RDing Product: TEMPer1F_H1_V1.4 Release: 1 Interface: 0 Device Found type: 0c45 7402 path: /dev/hidraw1 serial_number: Manufacturer: RDing Product: TEMPer1F_H1_V1.4 Release: 1 Interface: 1 unable to open device root@localhost:/usr/local/src/hidapi-master/hidtest# ./hidtest-libusb Device Found type: 0c45 7402 path: 0003:002e:00 serial_number: (null) Manufacturer: RDing Product: TEMPer1F_H1_V1.4 Release: 1 Interface: 0 Device Found type: 0c45 7402 path: 0003:002e:01 serial_number: (null) Manufacturer: RDing Product: TEMPer1F_H1_V1.4 Release: 1 Interface: 1 unable to open device root@localhost:/usr/local/src/hidapi-master/hidtest#
… then I tried the following (changed the directory):
root@localhost:/usr/local/src/hidapi-master/hidtest# cd .. root@localhost:/usr/local/src/hidapi-master# cd linux root@localhost:/usr/local/src/hidapi-master/linux# ./hidtest-hidraw Device Found type: 0c45 7402 path: /dev/hidraw0 serial_number: Manufacturer: RDing Product: TEMPer1F_H1_V1.4 Release: 1 Interface: 0 Device Found type: 0c45 7402 path: /dev/hidraw1 serial_number: Manufacturer: RDing Product: TEMPer1F_H1_V1.4 Release: 1 Interface: 1 unable to open device root@localhost:/usr/local/src/hidapi-master/linux#
… then I tried this (changed the directory again):
root@localhost:/usr/local/src/hidapi-master/linux# cd .. root@localhost:/usr/local/src/hidapi-master# cd testgui root@localhost:/usr/local/src/hidapi-master/testgui# ./testgui
… and it finally opened this window:
… then I tried connection to the first device listed (although both seemed the same):
… then I tried to “Send Output Report” (did not return anything back), following by “Send Feature Report” (it just closed that window prematurely), then re-opened that GUI again, following by “Get Feature Report” that returned some bytes see bellow:
… that was all with that GUI. (Connecting to the second device listed was possible but sending/receiving reports failed with some unclear error messages.)
Well, I got back to work with TEMPered package again:
root@localhost:/usr/local/src/hidapi-master/testgui# cd /usr/local/src/TEMPered-master root@localhost:/usr/local/src/TEMPered-master# root@localhost:/usr/local/src/TEMPered-master# make This
