DS18B20 on BigTreeTech Pi v1.2

BTT Pi uses AllWinner H616 CPU, and on https://github.com/bigtreetech/CB1 system, w1-gpio kernel module does not work.

However, there is an excellent custom module https://github.com/pstolarz/w1-gpio-cl

The following steps were tested on CB1 v2.3.3.

Wiring

DS18B20 Pinout
BTT Pi GPIO

Connect sensor VCC pin to 3.3V, GND to GND (obviously), and signal pin to selected GPIO. I used PC7, since it corresponds to the default w1 pin location on the Raspberry Pi header.
Don't forget to add a pull-up resistor between 3.3V and the signal pin. A 4.7 kOhm resistor is the recommended value.

NEVER connect anything while the printer is powered on!

I did not try parasitic power mode, and I don't recommend it. Klipper will shut down on subsequent read errors, and it might ruin your prints randomly. I did not have any problems with the standard 3-wire connection yet.

Compilation on CB1 system

The easiest way is to compile it directly on the device. The official guide needed to be modified slightly.

  1. sudo apt-get install build-essential bc bison flex libssl-dev
  2. sudo apt-get install linux-headers-current-sun50iw9
  3. git clone https://github.com/pstolarz/w1-gpio-cl.git
  4. cd w1-gpio-cl
  5. ln -s /lib/modules/`uname -r`/build/include/linux w1
  6. make
  7. sudo make install

DKMS

Optionally, you can install it using DKMS

sudo dkms add .
sudo dkms install w1-gpio-cl/1.2.2

where 1.2.1 is the latest w1-gpio-cl release version.

Installation

For details, read the original README.

Pin Selection

The w1-gpio-cl module does not accept pin names; instead, it needs pin index. To list all available pins, run

sudo cat /sys/kernel/debug/pinctrl/300b000.pinctrl/pinmux-pins

Find your preferred pin (note that some pins might not work). I used PC7

pin 71 (PC7): UNCLAIMED

Now you can configure module options

echo 'options w1-gpio-cl m1="gdt:71"' | sudo tee /etc/modprobe.d/w1-gpio-cl.conf

Test Config

Try loading the module manually

sudo modprobe w1-gpio-cl

Verify that the module is loaded

lsmod | grep w1

You should see something like

w1_therm               28672  0
w1_gpio_cl             16384  0

You can verify the output of the dmesg for errors.

Automatic Loading

To load the module during boot, run

echo 'w1-gpio-cl' | sudo tee /etc/modules-load.d/w1-gpio-cl.conf

Reboot and verify that the module is properly loaded and working.

Configuration

See https://www.klipper3d.org/Config_Reference.html#ds18b20-temperature-sensor

Find out connected sensor addresses

sudo ls /sys/bus/w1/devices/

You will see output like

28-011319f769fe  w1_bus_master1

With that address, add a Klipper config section like this

[temperature_sensor my_sensor]
sensor_type: DS18B20
serial_no: 28-011319f769fe
sensor_mcu: CB1

Note that sensor_mcu must be set to the host, which is CB1 by default.

After restarting Klipper, your new temperature sensor should appear in the Mainsail/Fluidd UI automatically.

Hello, I am not getting the "w1_therm" output and the id. Do you have any idea what I am doing wrong? Thanks for the tutorial!

Sorry to hear that. Please create a gist with your dmesg output, otherwise there is not much to go on.

@mdvorak Good to know my module is still alive, working on platforms I even didn't think about while creating it... I've added small fix in the project's Makefile so there is no need to create link manually as described in the README. You may check it out.

I have a V0 printer that uses BBT PI and TFT35 SPI.
I have install your fix for the ghost touches. It works really well untill I install the software to use the DS18B20 1 wire thermistor according your repo.
As soon as I have the thermistor working, the ghost touches comes back.
If I re-install your ghost touches fix, if works again, but I loose the DS18B20 thermistor.

The software I used to fix the ghost is : https://github.com/freakydude/cb1-os-build

Do you know what could cause that problem ?
Is there a way to fix it so both things are working together ?

Thank you so much for creating this guide. I would not have figured this out on my own.

Hello. I have followed your guide but not getting any ID's from the 2 sensors I have hooked up. I am running a CB1 EMMC so I don't know if that makes anything different or not. Here is my dmesg output

Hm, according to dmesg, module is loaded without error:

[    8.045259] w1_gpio_cl: loading out-of-tree module taints kernel.
[    8.051683] w1_gpio_cl: module verification failed: signature and/or required key missing - tainting kernel

Check again output of lsmod | grep w1 and then sudo ls /sys/bus/w1/devices/. If everything is OK but no devices are found, I would revisit wiring again. Also, try only one (or better, different) sensor. Cheap china clones are not always 100% functional.

sudo ls /sys/bus/w1/devices/

Here is the output I get from what you asked. Going to wire up a single sensor and give that a try. Im wondering if its because the CB1 EMMC has different GPIO numbers than the regular CB1 or BTT Pi

biqu@BTT-CB1:~$ lsmod | grep w1
w1_gpio_cl             16384  0
biqu@BTT-CB1:~$ sudo ls /sys/bus/w1/devices/
w1_bus_master1
biqu@BTT-CB1:~$

It does not seem like sw issue, so check the hw.

Just tried another single sensor. Same thing, not getting anything. Took that same sensor and hooked it up to a D1 Mini with ESP Home and I get an address from it and temp readings. Sensor is good. So its a SW issue.
