J’ai donc pris une clef USB afin de mesurer la température du Rack de Raspberry :
- TOOGOO(R) Or TEMPer PC portable capteur USB Thermometre Temperature Collecteur de Donnees Enregistreur : 6,41 Euros.
( voir l’article : https://www.cyber-neurones.org/2018/10/si-tu-nas-pas-de-salle-serveur-a-50-ans-on-peut-dire-que-tu-as-rate-ta-vie/ ) .
Quand on branche la clef USB sur le Raspberry on peut lire via dmesg :
[167573.702646] usb 1-1.4: new full-speed USB device number 6 using dwc_otg
[167573.835187] usb 1-1.4: New USB device found, idVendor=413d, idProduct=2107
[167573.835203] usb 1-1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0

C’est un premier bon signe 🙂 Par contre la suite c’est pas top :
[167573.903681] hid-generic 0003:413D:2107.0002: input,hidraw1: USB HID v1.11 Keyboard [HID 413d:2107] on usb-3f980000.usb-1.4/input0

J’ai donc pris le projet suivant ( Plan A ) : https://github.com/bitplane/temper.git :
$ cd /usr/local/src/
$ sudo git clone https://github.com/bitplane/temper.git
Clonage dans 'temper'...
...
$ cd temper/
$ sudo make temper
gcc -Wall temper.c pcsensor.c -o temper -lusb
In file included from temper.c:8:0:

Makefile:8 : la recette pour la cible « temper » a échouée
make: *** [temper] Erreur 1
Si c’est ainsi c’est qu’il faut installer les libs pour USB :
$ sudo apt install libusb-1.0-0-dev cmake
Je tente à nouveau une compilation :
$ sudo make temper
gcc -Wall temper.c pcsensor.c -o temper -lusb
In file included from temper.c:8:0:
pcsensor.h:25:17: fatal error: usb.h: Aucun fichier ou dossier de ce type

Makefile:8 : la recette pour la cible « temper » a échouée
make: *** [temper] Erreur 1
Pas mieux … pas de panique, quand c’est ainsi on installe apt-file
$ sudo apt install apt-file
...
$ sudo apt-file update
...
$ apt-file search /usr/include/usb.h
libusb-dev: /usr/include/usb.h
Ok, il fallait donc installer libusb-dev et non libusb-1.0-0-dev . Effectivement la version générique est toujours préférable.
$ sudo apt-get install libusb-dev
$ sudo make
gcc -Wall temper.c pcsensor.c -o temper -lusb
pcsensor.c:50:18: warning: ‘reqBulkLen’ defined but not used [-Wunused-const-variable=]
const static int reqBulkLen=8;
Un petit test :
$ sudo ./temper
Il n’affiche rien. Je vais essayer le plan B : https://github.com/edorfaus/TEMPered .
$ sudo git clone https://github.com/edorfaus/TEMPered
$ cd TEMPered/
$ sudo cmake .
...
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

...
Nouvelle erreur, on ne perd pas courage. On fait l’installation des headers :
$ sudo apt-get install libhidapi-dev -y
Et on refait une compilation :
$ sudo cmake .

On passe au plan E : https://github.com/edorfaus/TEMPered/issues/51 . J’ai l’impression que c’est le même problème que moi. En fait le plan E est au mauvais plan B.
Effectivement dans libtempered/temper_type.c , j’ai :

.vendor_id=0x0c45,
.product_id=0x7401,

},
{
.name="TEMPerV1.2 or TEMPer2V1.3",
.vendor_id=0x0c45,
.product_id=0x7401,
.interface_number=1,
Je fais donc une première modification :
{
.name="TEMPerV1.2 or TEMPer2V1.3",
.vendor_id=0x413d,
.product_id=0x2107,
.interface_number=0
},
{
.name="TEMPerV1.2 or TEMPer2V1.3",
.vendor_id=0x413d,
.product_id=0x2107,
.interface_number=1,
Et j’ajoutes la structure 0x04 qui est une copie de la 0x02 :
(struct temper_subtype*)&(struct temper_subtype_hid){
.base = {
.id = 4,
.name = "TEMPer2V1.3",
.open = tempered_type_hid_subtype_open,
.read_sensors = tempered_type_hid_read_sensors,
.get_sensor_count = tempered_type_hid_get_sensor_count,
.get_temperature = tempered_type_hid_get_temperature,
},
.sensor_group_count = 1,
.sensor_groups = (struct tempered_type_hid_sensor_group[]){
{
.query = {
.length = 9,
.data = (unsigned char[]){ 0, 1, 0x80, 0x33, 1, 0, 0, 0, 0 }
},
.read_sensors = tempered_type_hid_read_sensor_group,
.sensor_count = 2,
.sensors = (struct tempered_type_hid_sensor[]){
{
.get_temperature = tempered_type_hid_get_temperature_fm75,
.temperature_high_byte_offset = 2,
.temperature_low_byte_offset = 3
},
{

Et le test :
$ sudo /usr/local/bin/tempered
/dev/hidraw1 0: temperature 13.57 °C
/dev/hidraw1 1: temperature 78.12 °C
Miracle, cela fonctionne !
Nouveau test :
$ sudo /usr/local/bin/tempered
/dev/hidraw1 0: temperature 13.72 °C
/dev/hidraw1 1: temperature 78.12 °C
Par contre cela affiche n’importe quoi … il faut donc modifier :
.sensors = (struct tempered_type_hid_sensor[]){
{
.get_temperature = tempered_type_hid_get_temperature_fm75,
.temperature_high_byte_offset = 2,
.temperature_low_byte_offset = 3
},
{
.get_temperature = tempered_type_hid_get_temperature_fm75,
.temperature_high_byte_offset = 2,
.temperature_low_byte_offset = 3
}
Mais il faut aussi modifier libtempered/type_hid/fm75.c :
A la place de :
// This temperature formula is taken from the FM75 datasheet.
// This is the same as dividing by 256; basically moving the
// decimal point into place.
*tempC = temp * 125.0 / 32000.0;
Mettre :
*tempC = temp / 100.0;
Nouveau test :
$ sudo /usr/local/bin/tempered
/dev/hidraw1 0: temperature 35.12 °C
/dev/hidraw1 1: temperature 35.12 °C
Je vais maintenant vérifier … mais il me semble que 35 c’est bon.
Et un plan F pour bien Finir : https://github.com/mreymann/temperx

/dev/hidraw1 : 413d:2107 interface 1 : (null) (null)
/dev/hidraw2 : 0eef:0005 interface 0 : WaveShare WS170120
Ensuite installation de go
$ sudo apt-get install go
$ mkdir go
$ export GOPATH="$HOME/go"
$ go get github.com/mreymann/temperx
$ go install github.com/mreymann/temperx
$ sudo go/bin/temperx

$ sudo ln -s /usr/share/munin/plugins/temperx /etc/munin/plugins/temperx
$ sudo systemctl restart munin-node.service
$ sudo munin-node-configure | grep temperx
temperx | yes |
C’était vraiment la misère …
J’ai modifié le code GO pour avoir :
$ sudo go/bin/temperx
Temperature.value 40.87
Humidity.value 200
Modifier go/src/github.com/mreymann/temperx/temperx.go :
fmt.Printf("Temperature.value %v\nHumidity.value %v\n", tmp, hum)
Sinon j’avais l’erreur dans /var/log/munin/munin-update.log .
Aie toujours pas bon :
