Hello. I need help please 🙂 I finished assembling my Pidog, and the integration with the chatGPT API works fine but only when I use the keyboard. I can’t get voice commands to work. However, when I test the microphone (Rec op.wav, sudo play op.wav) everything works, but when I launch the pidog, I get the error message “/bin/sh: 1: pinctrl: not found” which crashes everything. I made sure that my microphone was set as the default audio input in asound.conf but it still doesn’t work. Here is what I get: philemonii@raspberrypi:~ $ cd ~/pidog/gpt\_examples/ sudo ~/my\_venv/bin/python3 gpt\_dog.py /bin/sh: 1: pinctrl: not found config\_file: /home/philemonii/.config/pidog/pidog.conf robot\_hat init … done imu\_sh3001 init … done rgb\_strip init … done dual\_touch init … done sound\_direction init … done sound\_effect init … done /bin/sh: 1: pinctrl: not found ultrasonic init … done vilib 0.3.11 launching … picamera2 0.3.12 Web display on: [http://192.168.0.250:9000/mjpg](http://192.168.0.250:9000/mjpg) Starting web streaming … - Serving Flask app “vilib.vilib” (lazy loading) - Environment: production WARNING: This is a development server.

Edit: I erased the sim card and reinstalll everything from scratch: I still get the same error. ---

Pinctrl is relatively new but afaik, it should be included as part of all recent pi raspbian OS’ It can be installed manually if using another / legacy OS. Try to run the pinctrl command on the CLI, maybe it will give you extra debug info? The full sf command is pinctrl set 20 op dh But not sure if that’s safe to run without any prior setup! ---

thank you! I’ll wait for the Sunfounder advice before doing it manually as I’m not sure what GPIO 20 does. Thanks again for your help. I studied programming science, but it was 20 years ago so I’m a bit rusty. ---

It enables the speaker according to the comment in the code os.popen(“pinctrl set 20 op dh”) # enable robot\_hat speake switch But just run it without parameters to see if you have the command… or even safer use which pinctrl To see if it’s on your path but you’re right, the weekend is almost over, so best to await Sunfounder ---

> [@Spf650](#): > > which pinctrl I started with “which pinctrl” few days ago. no luck. I also tried to download it 🙂 sudo apt-get update sudo apt-get install pinctrl Nothing found. It’s weird because the speaker works well. It’s the microphone that seems to be the problem. (Mic works when I test it, but not when I engage it with the openAI API. ). ---

i know you are awaiting an answer from Sunfounder, so this is just FYI AFAIK pinctrl is not available under apt, you need to build from github source or use an OS with it included. Focussing on the microphone aspect, the recognizer web page has several trouble shooting suggestions depending upon your chosen microphone > **[SpeechRecognition](https://pypi.org/project/SpeechRecognition/)** > > Library for performing speech recognition, with support for several engines and APIs, online and offline. ---

Sorry, this is an issue with robot\_hat code not being compatible with the bullseye system because bullseye is missing the pinctrl used to set gpio 20 high to enable speaker, we have fixed the robot code. Please update and reinstall: cd ~/robot-hat git pull sudo python3 setup.py install sudo bash i2samp.sh It is also recommended that you use the latest bookworm version of the Raspberry Pi, as code maintenance may not be as up-to-date for compatibility issues with older systems. ---

Thank you so much! I’ll install the bookworm version: we were using the Legacy version, as instructed earlier. Have a nice day.
