[opensuse-arm] Temperature sensor of DHT11
Hi I want to control the temperature sensor of DHT11 on openSUSE15 on Raspberry Pi 3B+. Now I try to develop python3 application with mraa. I want to know if openSUSE Leap 15 on Pi can handle DHT11 sensord with default or not. And what kind of action do I need to control this sensor with openSUSE Leap 15 ? Best Regards.

You will probably need kernel-default-extra package to pull in the driver. After that you have to create a device tree overlay which gets loaded by u-boot (by adding it to /boot/efi/extraconfig.txt).

DHT11 driver is not enable: https://kernel.opensuse.org/cgit/kernel-source/tree/config/arm64/default?h=o... I guess we should enable it.
After that you have to create a device tree overlay which gets loaded by u- boot (by adding it to /boot/efi/extraconfig.txt).
You just need to add: dtoverlay=w1-gpio,gpiopin=X and replace the X with the wanted GPIO number used for the 1-wire interface. Then, your device should appear on /sys/bus/w1/devices/ You should be able to read registers manually (since the kernel driver is not enabled yet). Cheers, Guillaume

That's a pity. Yes we definitely should enable it. Could you send a patch? While at it, I think it would make sense to go through IIO subsystem and enable all drivers as long as there is no good reason to not do that. Regards, Matthias

I will probably not be able to send a patch this week.

I agree. Cheers, Guillaume

Whenever I updated the arm configs I did enable all new iio modules. Unless Yousaf missed something, we probably just didn't enable old ones? Feel free to go ahead and enable them, but try to check history for whether someone disabled them for a reason, such as them being specific to non-arm platforms (e.g., git blame / git gui in local repo). I recall a few iio drivers conflicting with their hwmon counterparts.

Hi Thank you for your information. Currently I can find 1-wire interface after reboot. I will try to get the register value. Best Regards.
