Are you using w1-gpio overlay ? Are you defining the param_w1_pin parameter properly (without it, default is PD14 pin) ?

 

I used its config for a long time. It works very well in 16.04 .

 

overlays=pps-gpio uart1 usbhost0 w1-gpio
param_w1_pin=PA10
#param_w1_pin_int_pullup=1
param_pps_pin=PA7

 

now:

Why the pullup is commented out ? Do you have an external one ?

This doesn't come from Armbian patches, maybe a bug have been introduced upstream ...

On my side, my DS18B20 is registering properly on my OPi_2E under 4.19.2 :

whether commented or not, no any difference. 

 

I use a 5.1K pullup external.

Dear Sirs,

 

I read every topic in this thread (what helped me a lot), but now I'm stucked and need more help.

 

I did buy this sensor and I need to use it on my Orange Pi PC.

 

After following the instructions from this site together with the instruction of this thread, I wired the 3 cables like this:

RED -> 2 (5V)

BLACK -> 6 (GND)

YELLOW -> 35 (PA10)

 

My files are like this:

 

root@orangepipc:/sys/bus/w1# cat /etc/modules-load.d/modules.conf

It seems that I have 2 sensors:

 

root@orangepipc:~# cat /sys/devices/w1_bus_master1/w1_master_slave_count
2

 

But it seems that I don't have any files where to read the data... Example:

Does anybody knows what I'm doing wrong?

 

Any help is appreciated.


Thanks.

While adding w1-gpio in /boot/armbianEnv.txt, you don't need to add it in /etc/modules-load.d/modules.conf ...

But you need to add "param_w1_pin=PD10" in /boot/armbianEnv.txt as well, otherwise it is defaulted to PD14.

 

Hello martinayotte!

 

Minutes after I posted my question, I found your first reply in another thread that lead me to the right path. I just don't replied here yesterday due to the limit of one post per day.

 

Beyond this, one of the pins was wrong. With Orange Pi PC and that sensor, the correct is use 3.3V, and not 5V. So, for the red wire, PIN 1, and not 2.

 

Now my temperature monitor system is alive and kicking!

 

Thank you very much!

Hello,

I know that this is about Armbian but maybe someone can help me anyway. The orangepi forum doesn't seem to accept new registrations ...

 

I try to activate one wire communication with my Orange Pi One with kernel version 5.3.5+. I use the Debian image.

I just want to read out a DS18B20 sensor.

 

I modified the /boot/orangepiEnv.txt as descibed in http://linux-sunxi.org/1-Wire and above
with this items:

 

---

root@OrangePi:~# cat /boot/orangepiEnv.txt
verbosity=1
logo=disabled
console=both
disp_mode=1920x1080p60
overlay_prefix=sun8i-h3

 

overlays=w1-gpio usbhost0
param_w1_pin=PA10
param_w1_pin_int_pullup=0

---

 

If I make "ls /sys/bus/w1/devices/" there is no w1 directory.

where is the mistake? Does debian not support w1?

 

Greetings Axel

Those settings should be in /boot/armbianEnv.txt using an Armbian image ...

Hello, yes, that's how I understood it.

I thought that Debian also works....

 

If it makes sense, I'll switch to armbian.

Is armbian the better choice for hardware-related applications?

The DT overlay isn't written to support multiple buses ...

But, again, why do you need more than one bus, since OneWire support multiple devices on the same bus ?

To respond on your question - I have 50x DS18B20 on breadboard with OPiZ (don't ask why). Out of these 50, max 24 works at the same time. If I connect more  to the bus they randomly drop out and/or give false readings.

I would also like to know how to configure more than one w1 bus.
