How do enable 1-wire on the BTT-Pi, specifcally for the DS18B20 sensor?

The product died after just ONE DAY of use. As you can see on issues here on github and on other parts of the internet, i'm by far not the only one with the same problem. So i was sure BTT will replace or refund it fairly quick, but i was so wrong.
"Support" if you can call them so, always promises to replay in a few days and then just silence.
After at least 4 contacts I now just give up my money and throw that board away. My time invested in this case is by far more worth than this SBC!
Company doesn't want to replace or refund, with no further explanation. So my conclusion is to stay away from Big Tree Tech if you want high quality or any usable support if something goes wrong.

Be assured i will never ever purchase any BTT product again!

Hello everybody!
How do I fix the ip on both eth0 and wlan0?

Trying to determine which pins on the GPIO are tied to the i2c interface. There is an overlay and i2c device defined in the BoardEnv.tst file but don't see any documentation or notation in the pins diagram on which pins these are connected to on the GPIO header.

Hello, can you provide the reference of the connectors used on the board?

I'm searching for the exact reference of the CAN connector, I can't find it anywhere

Hi, i have a BTT-PI V1.2 and i'm trying to wire the ADXL345 sensor to the GPIO pins.

This is my configuration

[mcu rpi]
serial: /tmp/klipper_host_mcu

[adxl345]
cs_pin: None
spi_bus: spidev1.2

[resonance_tester]
accel_chip: adxl345
probe_points: 117.5,117.5,10

I've wired the sensor as follows

VCC -> 3.3V (Yellow pin)
GND -> GND (Black pin)
CS -> PG12
SDO -> PH8
SDA -> PH7
SCL -> PH6

I've tried with all the spi_bus in BoardEnv.txt, but nothing, it doesn't work.

Any clue?

The step file takes a very long time, relatively, and I realized that every Designatorxxx tag has a sub-part of a text logo, called LOGO?xxx.

These are made up of letters, shown here:

and here:

These are in every single part! Please remove them.

Hello everyone I found the instructions for starting the display. There is one but... It is only for ORANGE pi3. Does anyone have the opportunity to fix the driver for our CPU? Or how can it be used?

Mthe first day it run normal. I config klipper, and print some model file. But second day it not work. Power led is light but nothing happen. Device not turn on,

anyone help me pls 🥹
btt pi v1.2 fan pin issue

When I connect my ADXL345 to the dedicated port on the BTT-PI and enable KlipperScreen I get a blank white screen.

If I enable one or the other I get both to work just fine without issue. But enabling both in BoardEnv.txt. will not work.

Using the following image:
V2.3.2

BoardEnv.txt Setting

uncomment for TFT35_SPI screen
#overlays=tft35_spi
overlays=tft35_spi spidev1_2

uncomment to release 'spidev0.0' to user space
overlays=spidev0_0

I am stumped as how to get both to work as the documentation for the BTT-PI has sections for wiring and enabling both options. But they will not work if both are enabled at the same time

I'm looking for an extension cable for mount a external wifi antenna. I brought one bit the connector are too small. I need with one head SMA.
Thanks

I have bought a BTT-Pi and the U2C pinboard,bt when I assemble them, the PI does not find the canbus...
Is there somewhere an explanation on how to enable the U2C pinboard?

Is it possible to connect more than 1 printer to the BTT Pi? If so are there any documentation on how to do this. Thanks

Issue: There is a positive and negative 12v connection close enough to the mounting screw holes that using an m3 screw instead of an m2.5 screw will cause a short. I found this out when my board started glowing by the mounting hole next to the USB C and smoke came out. Earlier a spark came from the hole on the other side of the SD card.

Since this is a 3D printer board above all and m3 screws fit with minimal resistance, this is a major cause for concern. The fix should be easy though: just add a little more clearance between power and GND.

I would love to recommend this board to my friends, but I can't do that with an easy short right there. Can we get a fix?

Hello,
I just received Btt Pi v1.2 and hooked it up with Octopus Pro and U2C.
Now the problems.
BTT Pi communicates with Octopus pro ony with the original USB C cable that came with the Octopus. Any other C cable I have got does not work and lsusb does not show anything.
U2C does not appear on the list even with that cable. I cannot see it.
When connecting one device at the time.
I also tried to hook up the SB2209 / SBB2240 so I can update the firmware. It does not see it and it does not light the ligts on it.
Even when using the same cable as for the Octobus.
Trying other three USB 2.0 slots does not help.

Now the fun part. I used any other cable with the U2C, or the SB2209 and it works with my laptop. Windows immedietely sees the device and I can even put them to DFU mode. All LEDs on both devices also light up correctly.

It looks like a fault of the Pi, but I have no idea how to resolve it. If it is even possible.
Thanks in advance for any advice!

Is it possible to teach BTT Pi to run from USB?

To change my static IP address, I need to edit /etc/dhcpcd.conf by running sudo nano /etc/dhcpcd.conf however, if I am connected as biqu , it tells me access denied. To make this working on a btt-pi2, I need to connect as root with the password root. But this doesnt work on the btt-pi v1.2

This is constant. I saw other folks having issues similar on the armbian forums.

Is there such a thing as a BTT Pi 2 manual and firmware? I couldn't find one.

Hello,

I can't open the file on github, my browser, my pdf preview app.
Am'i the only one ?

Regards,

Hi, I have bought several BTGT Pi v.12 devices. I am using 2 of them as host machines for CNC/Klipper and they are great.

However, I now have a maker project outside of CNC/3d Printing that I would like to use one for, but I need to access the GPIO pins via Python. Specifically, I need to output on 3 pins, and read from at least two.

I can't seem to find how this is done. Can you please let me know the basics of how I can read/write from/to the GPIO pins using python?

Hello,

Is this board compatible with official Raspberry image?

THX,RH

Dear all, I have one of my BTT Pi inside a Klipper machine, working with the code you provided to make the fan run, without any problem, but, I have a concern, when you are developing something, or simply you will not use this BTT-Pi for klipper, the fan remains stopped, and maybe the CPU will become hot, then, from my point of view, could be a great idea to have something similar as the Raspberry pi has, in order to control the fan in a regulated way, directly as a part of the OS, enclosed I send you three pictures in order to explain what I mean:

Sajnos a mellékelt kinyomtatható ház elég sok sebből vérzik, a HDMI, audio és tápcsatlakozók lyukainál a "bottom" és "middle" szekcióban kívűl mélyítést kellett készítenem, hogy a csatlakozók műanyag foglalatai elférjenek és a csatlakozók helyesen üljenek be az aljzatokba, illetve az alaplapi JI5 csatlakozó mellyett belül kivágást kellett csinánom, mert vastag a burkolat és nem fér el. A "bottom" fájban az USB csatlakozó melletti bepattintós lyuknál hibás a szerkesztés, illetve a "middle" szekciónak végül a teljes belsejét kivágtam, mert a hűtőborda miatt nem fér el. Sajnos a chip eléggé melegszik, így mindenképpen szükséges a hűtőborda, sőt úgy tűnik, a ventilátort sem lehet megspórolni. Ha valakit érdekel, a módosításokat feltöltöm a Thingiverse-re.

Hi, I have followed the manual for the SB2240, but when I try to flash the SB2240 via Can I get flash error

ERROR:root:Flash Error

During handling of the above exception, another exception occurred:

Please advise to fix.

I just got my BTT Pi set up instead of Rpi. Works very well.
The display is heavily flickering and fading in and out.
Problem only exist on Klipperscreen, not in terminal/console.

What could be wrong?

I'm using UART0 (ttyS0) to connect to klipper-mcu.

Hi,

I've connected fan on PG19 pin and Klipper doesn't recognize them. Do you have a config to make it work?

error mainsail : Pin 'PG19' is not a valid pin name on mcu 'mcu'

actually I've bypass with one pin on my board but I want to use PG19 pin on BTT PI

Hi, there is a lot of documentation on how to connect an ADXL345 on a CB1 or CM4, and their configuration on Klipper. But I'm in trouble when I connect the BTT-ADXL345 to the BTT-PI by the supplied cable on the dedicated SPI port (page 7 of its manual).
In the pin out what is the right cs_pin number?

Hi all,
i have a PTTPi and a TFT35SPI V2.1, i've connected them with the ribbon cable provided with monitor.
Klipper and Klipperscreen are installed but the display is all white.
what i'm doing wrong?
i put the last log here, i can't see anything wrong
