The LMS has a command line interface that can be leveraged to remotely control audio playback: just telnet into the server pi on port 9090, and use the LMS CLI format. The parameter "set_GPIO" is used to assign GPIO to various functions. From there, simply run idf.py build to build, etc. When pressed it triggers a navigation up command. Thanks, Simon Find company research, competitor information, contact details & financial data for INFRATEX of MOUVAUX, HAUTS DE FRANCE. It has a 240x240 ST7789 screen and onboard audio. This is an example of a device that requires an I2C set of commands for its dac (see below). Squeezeplug multiroom audio. Default build ssid and passwords are "squeezelite"/"squeezelite". See below for more details. You can tweak how the vu-meter and spectrum analyzer are displayed, as well as size of artwork through a dedicated menu in player's settings (don't forget to add the plugin). For the sake of clarity, WROOM modules DO NOT work as they don't include PSRAM. This will guide you through a sequence of actions with the remote. [SOLVED] Mono Output with Squeezelite and IQAudio Pi-DigiAMP+ The default build is a generic firmware named I2S which can be configured through NVS to produce exactly the same results than dedicated builds. It might be related to this, especially since I only encountered this issue in the setup where audio output is shared (my other setups based on the same squeezelite with exclusive access to the sound output do not show this problem). fr Synology NAS (mit Docker), ESP32-Microcontroller, Windows-PC, OSx, . pCP with LMS will manage music database and streaming. This is a demo of Logitech media server (LMS) rinning SqueezeAMP on an ESP32 MUSE board (20$). I've done my best to tweak these, but that level of optimization includes writing some assembly which is painful. The NVS "target" will be used to call target-specific code then, but again this is purely runtime, not compile-time. Jetzt laden wir squeezelite herunter, den Client. So if you want to add your own platfrom, please look very hard at the main\KConfig.projbuild to see how you can, using parameters below, make your device purely a configuration-based solution. SMI (Serial Management Interface) wiring is not fixed and you can change it either in the configuration or using "eth_config" parameter with the following syntax: To use the system SPI, shared with display (see spi_config) "host" must be set to -1. If you add more players you can enjoy a advanced multi-room audio system that can play in sync or play different streams in separate zones. I also successfully tested this setup using TSOP4838, taking into account its specific pinout. Hier liegen die aktuellen Versionen: https://sourceforge.net/projects/lmsclients/files/squeezelite/linux/ When selecting the same output device but with squeezelite plughw prefix (i.e. LCK - (WS - see below) The SW gpio is optional, you can re-affect it to a pure button if you prefer but the volume, longpress and knobonly options make little sense as the missing switch plays an important role in these modes. To access NVS, in the webUI, go to credits and select "shows nvs editor". As it turns out, streaming audio LMS takes less than 3% CPU time on the server, while on the client side squeezelite takes about 10-20% CPU time. Buttons, rotary encoder, amplifier control and power are supported. This will force a reboot. -s ist die Server-Adresse So I went for the old-style option : a remote control. Be aware that when using non "raw" mode, the CLI (Command Line Interface) of LMS is used and must be available without password, There is no good or bad option, it's your choice. To get an audio output an I2S DAC can be used. Status / restart squeezelite & squeezeboxs #3 - GitHub Some designs might add it externally, but it's (very) unlikely. You can define the defaults at compile time but nvs parameter takes precedence except for SqueezeAMP and A1S where these are forced at runtime. If you want to use it solely as a media player, we recommend to use the Squeezelite-ESP32 firmware . First, if there are better suited subreddits about this subject, just let me know :) I use Logitech Media Server along with Squeezelite for years as my DIY multi room audio server and players. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Ich bin nicht so tief in der ganzen Linuxmaterie drin, aber wie kann ich dafr sorgen, dass der Squeezeplayer sich ohne Putty und nach jedem Reboot automatisch startet? Eine Mglichkeit hierfr wre sudo nano /etc/rc.local zu ffnen und hier noch vor EXIT 0 den Befehl squeezelite -o sysdefault:CARD=Headphones -d output=debug -a :::0& einzutragen. The philosophy is to minimize as much as possible platform-specific code and use of specific #ifdef is prohibited, no matter what. To me the squeezelite sounds better on Volumio as compared to Squeezelite on Pogo plug . There is an issue with sync detection in 1.15.1b from where the original stack patch was done but since a few fixes have been made wrt sync detection. Die technische Speicherung oder der Zugriff, der ausschlielich zu anonymen statistischen Zwecken verwendet wird. I chose to turn it into a background service/daemon, using these great instructions. It does not matter for 16 bits samples but it has been chosen to truncate the last 4 bits for 24 bits samples. Scale is a float ratio applied to every sample of the 12 bits ADC. You can find various help & instructions here. RetroPie, NAS, ..) mit einem immer aktuellen Raspbian / Raspberry Pi OS erledigen. When using them for a button, a 100ms polling is started which is expensive. There are plenty of SW options to choose from, I chose to use the well-known (if somewhat ageing) Logitech Media Server open source music server. Any support is appreciated as it helps us to keep our server running and to get new hardware for testing. This will reboot the ESP32 into recovery, where additional configuration options are available from the NVS editor, for codecs libraries, add -mlongcalls if you want to rebuild them, but you should not (use the provided ones in codecs/lib). Here are a few one-liner examples: For a basic use, just binding remote control commands from LIRC to some of these actions will work just fine, just configure the LIRC daemon to associate specific actions to each key code. It offers the following capabilities. Use the esp-idf 4.0 https://github.com/espressif/esp-idf/tree/release/v4.0 and a recent add esp-dsp (after 08/2020), When initially cloning the repo, make sure you do it recursively. Die Lsung ist, squeezelite mit dem Zusatz -a :::0 zu starten, also in meinem Beispiel so: squeezelite -o sysdefault:CARD=Headphones -d output=debug -a :::0, Quelle: Multi-Room Home Audio Boot the esp, look for a new wifi access point showing up and connect to it. If you want coax, you can also use a poor-man's trick to generate signal from a 3.3V GPIO. cd squeezelite For the system control/user interface, the usual way is to rely on LMS web interface, or the corresponding phone app. Multirooms is great at home when you want to have the same music. The optional "miso" (MasterInSlaveOut) parameter is only used when SPI bus is bi-directional and shared with other peripheral like ethernet, gpio expander. Go into the NVS editor tab to change NFS parameters. Please note that you can not use the same GPIO or port as the DAC. pCP is a high quality audio player via Squeezelite. Squeezelite-esp32 is an audio software suite made to run on espressif's ESP32 wifi (b/g/n) and bluetooth chipset. GitHub - RASPIAUDIO/squeezelite-MuseLuxe Case 1: Raspberry Pi with Sound card With a DAC, Digi or AMP HAT, a wide variety of speakers can be connected to the Raspberry Pi. Logitech original commercial audio player) emulator, using ALSA for audio output. The second set is in the living room where I already have an amplifier, so all I need is a DAC there. squeezelite multi room - Help - Volumio The DC parameter is needed for displays. 'artwork' enables coverart display, if available (does not work for Bluetooth). Added script for generating docum, cmake on esp-idf V4.0 - testing version - release, Add GPIO config for Infrared on SqueezeAMP 3.20, Setup squeezelite command line (optional), Additional configuration notes (from the Web UI), Rebuild codecs (highly recommended to NOT try that), https://www.espressif.com/en/products/modules/esp32, https://github.com/rochuck/squeeze-amp-too, https://www.instructables.com/id/ESP32-Development-on-Windows-Subsystem-for-Linux/, https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/windows-setup.html, https://github.com/espressif/esp-idf/tree/release/v4.0, 192k is very challenging, especially when combined with display, 48kHz max (after resampling) - equalization skipped on >48k tracks, Stream your local music and connect to all major on-line music providers (Spotify, Deezer, Tidal, Qobuz) using, Automatic initial setup using any WiFi device, Full web interface for further configuration/management, key2: GPIO13, key3: GPIO19, key4: GPIO23, key5: GPIO18, key6: GPIO5 (to be confirmed with dip switches), D4 -> GPIO22 used for green LED (active low), The IO connector also brings GPIO5, GPIO18, GPIO19, GPIO21, GPIO22 and GPIO23 (don't forget it's muxed with keys! So gehts: die dazugehrigen SD-Karten fr eine einzige Nutzung opfern zu mssen, habe ich nach einer Alternative fr meine Volumio-Multiroom-Audio-Lsung gesucht. No problem on that side. As said before, this is more than enough for any human ear. A measure is taken every 10s and an average is made every 5 minutes (not a sliding window). Gerrelts script will do fine. You can also disable the SBR extension of AAC codecs as it consumes a lot of CPU and might overload the esp32. The players run on several RaspberryPi's and computers. On the SW side, the LIRC library is perfect to decode commands from the remote, and the pyLIRC python wrapper for LIRC provides a convenient API (a C program would be fine too, but Im lazy). In addition of the esp-idf serial link monitor option, you can also enable a telnet server (see NVS parameters) where you'll have access to a ton of logs of what's happening inside the WROVER. How to set up multiple instances of Squeezelite on your Max2Play device (Raspberry PI, ODROID U3, ODROID C1) to get a multiroom sound solution with just one device! When pressed it triggers a volume up command. In my case, I mapped the following names/buttons: Edit the generated lircd.conf file and provide a name for your remote (e.g. Multisqueeze Add-on to run multiple instances of Squeezelite - YouTube Now, when I did the porting of squeezelite to esp32, I've also made the core 16 or 32 bits compatible at compile-time. At this point, the device should have disabled its built-in access point and should be connected to a known WiFi network. sudo apt-get install -y libsox-fmt-all libflac-dev libfaad2 libmad0, Auf einem frisch aufgesetzten Raspbian Lite fehlten noch weitere Pakete, diese installieren mit: pCP with LMS and Squeezelite player on the same Raspberry Pi. As of squeezelite 1.8, there is an option (, I encountered cases where mp3 music playback was too fast. A simple alternative to building the project's binaries is to leverage the same docker image that is being used on the GitHub Actions to build our releases. sle118/squeezelite-esp32 - GitHub FLT - GND The servers runs on a RaspberryPi connected to an external hard drive containing my music library. Nach einem Software-Update von Raspbian OS auf meinem Pi4 lieferte der squeezeplayer auf dem Headphone Output keinen Ton mehr. keyboard layout). Most displays require reset and will not initialize well otherwise. You can have as many of these configs as you can. Please note that you can not use the same GPIO or port as the I2C. The script uses an external configuration file to store the server IP address and its own MAC address, as well as the path to the file when outputs are logged. NB: You can use the pre-build binaries Muse4MBFlash which has all the hardware I/O set properly. This is a design choice I've made to preserve CPU performances (it is already stretching a lot the esp32 chipset) and optimize memory usage as we only have 4MB of usable RAM. This is not a perfect solution, and other ideas are welcome. This starts instance 2 of squeezelite with output to the bt speaker. You can connect the volume control for Squeezelite directly to your sound card by adding -o hw:0 -V Digital to the command line options of Squeezelite in its Advanced Settings menu you find in the Audioplayer tab. Free software that plays local music as well as online music streaming services on a Raspberry Pi. When not using system SPI, "mosi" for data out, "miso" for data in and "clk", The esp32 has a special I/O multiplexer for faster speed (up to 80 MHz) but that requires using specific GPIOs, which depends on SPI bus (See. To install the LIRC (Linux Infrared Remote Control) library that allows to read the TSOP IR receiver: For newer raspbian distros using the Device Tree mechanism, edit /boot/config.txt instead and add the line: To check that everything is in order, lets check audio streaming (you can just plug a set of earphones at the USB DAC output for now). Note that on SqueezeAMP, port must be 1. squeezelite -o sysdefault:CARD=Headphones -d output=debug lieferte: output_thread:759 start error: File descriptor in bad state. reset: some display have a reset pin that is should normally be pulled up if unused. The player is controlled using, and media is streamed from, a Logitech Media Server instance running somewhere on the local network. The benefit of the "raw" mode is that you can build a player which is as close as possible to a Boom (e.g.) The best option in that case is to let LMS proxy the stream as it will provide larger chunks and a "smoother" stream that can then be handled. Syntax is, NB: Set parameter to empty to disable battery reading. I2C parameters are optional and only needed if your DAC requires an I2C control (See 'dac_controlset' below). It will connect to the Logitech Media Server, and enable local audio playback of remote media stored on the LMS.
