Adafruit BusIO includes Adafruit 12CDevice. It’s called for in one of the libraries I’m including.
It is in my bulk Libraries folder and in the project /lib folder.
I used the PIO utility to add Adafruit BusIO.
PIO is refusing to cooperate again.
There’s a lot of yellow, and it mentions a poor conversion somewhere, but that isn’t given as the reason this code won’t compile. It’s the stinkin’ library. I don’t have enough copies of it.

By the way, adding the Tone32 library cleared ‘tone’ on my R32.
This will run on a WeMos D1 R32.
I’ve restarted the application about seven times and restarted the PC three times. I deleted the PIO folder three or four times.
Try adding to main.cpp:
#include <Adafruit_SPIDevice.h>
Something has changed as I’m having to include Adafruit_I2CDevice.h in several projects that would build before without it…
That was happening to me, the Adafruit_I2CDevice, but my frustration came from having it in the actual folder while it was asking me to add it.
I spend about half my time trying and failing to add libraries. That hassle blends in with the rest, I can’t resolve them. Even libraries I add with the PIO thing fail to get seen.
Since I’m doing what I’ve been told to do and it doesn’t work, I don’t think it works very well.
.
I just really started here a few months ago, from Arduino.
The following worked just fine for me…
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
monitor_speed = 9600
lib_deps =
paulstoffregen/Time
adafruit/Adafruit SSD1306
lbernstone/Tone32
In other words, I told PlatformIO to manage the libraries itself, and it did just fine. If you encounter the fatal error: Adafruit_SPIDevice.h: No such file or directory error… try adding lib_ldf_mode = chain+ or lib_ldf_mode = deep+ to the platformio.ini and see if that resolves it. It sometimes fails due to how Adafruit coded that particular include, and PlatformIO needs to work harder to figure out what they are doing.
You are probably also having issues due to the version of BusIO you are using… 0.0.2??? Really? This is what your dependency graph should have looked like…

Building in release mode
Perhaps this will help make library handling a little less painful. I hope so anyway. It’s based on my experience - I might have some stuff incorrect or incomplete below, hopefully I’ll be corrected if so.
I’m assuming PlatformIO version 5.0.0 and above, as some of this stuff is new. I’m also only “skilled” (for want of a better word) in AVR stuff at the moment, so the following is biased towards AVR kit - Uno, Duemilanove, NormDuino!
None of the following will be global, everything relates to local installations for the current project.
When you use lib_deps, the library details are passed to the pio lib install command to install the appropriate library locally.
Adding the following to lib_deps does different things:
lib_deps=servo will install a library which is built in to the framework you are using. I’m on AVR so I get the Arduino Servo library installed for my project. The install is local to this project only.
lib_deps=NormanDunbar/Servo will find and install the Servo library supplied by some bloke named NormanDunbar. In the event that there is a Servo library in the framework I’m using, it will not be used, only the NormanDunbar supplied one is used.
lib_deps=https://github.com/NormanDunbar/Servo.git will look for a Servo library, on GitHub.com, under a repository named “Servo” and in the user “NormanDunbar”. Don’t go looking though, there isn’t one!
lib_deps=NDServo=https://github.com/NormanDunbar/Servo.git I’m not sure about this one. I think it gives the afore mentioned GitHub Servo library, an alias? I’ve never used this option. Anyone want to jump in?
The above will just install a library, whichever happens to be the latest version. Usually, that’s fine. However, sometimes a new version of a library will cause problems, for example, and should be ignored.
lib_deps=servo@1.2.3 will only ever install and use Servo library 1.2.3.
lib_deps=servo@^1.2.3 is the recommended method to use. It will use the library version given, or any backwards compatible future versions.
lib_deps=servo@~1.2.3 will only ever install or use the Servo library, versions 1.2.x where ‘x’ is 3 or higher.
lib_deps=servo@>1.2.3 will use any version of the library greater than version 1.2.3. The highest version found will be used.
lib_deps=servo@>=1.2.3 will use any version of the library greater than or equal to version 1.2.3. The highest version found will be used.
lib_deps=servo@<1.2.3 will use any version of the library less than version 1.2.3. The highest version found which is lower than 1.2.3, will be used.
lib_deps=servo@<=1.2.3 will use any version of the library less than or equal to version 1.2.3. The highest version found which is lower than 1.2.3, will be used assuming that 1.2.3 is not found.
So, you have version 1.2.3 of the servo library, but version 1.2.4 is available but has a bug that stops it working for you. What to do? Simple, tell PlatformIO not to use 1.2.4.
lib_deps=servo@>=1.2.3,!1.2.4 will use any version of the library greater than or equal to version 1.2.3, but not version 1.2.4. The highest allowed version found will be used.Ah! But! There’s a version 2.0.0 out now, and it is not suitable for my board. 1.2.4 is still broken though. What can I do?
lib_deps=servo@>=1.2.3,!1.2.4,<2.0.0 will use any version of the library greater than or equal to version 1.2.3, but not version 1.2.4. The highest allowed version found which is less than version 2.0.0 will be used.Ok, this is all well and good, but I have written my own libraries and I’ve got them saved away safely in a central location. How can I use them in my projects? Especially as I just want all my projects to use them, I don’t want to install each one each and every time I start a new project?
Let’s assume that I have this sort of thing set up. I don’t, but let’s assume under my central library directory named /home/norman/SourceCode/Libraries/:
AVRusartcBufferIn each of those directories, I have the header and source files for my various libraries. I can therefore add the following line(s) to my ini file. There are three ‘/’ characters after the file word, because I’m on Linux. I suspect, Windows would use file://c:\whatever\wherever\something etc. (Don’t quote me!)
lib_deps=file:///home/norman/SourceCode/Libraries/AVRusart to include my USART stuff.If I need both libraries, I can do this:
lib_deps=file:///home/norman/SourceCode/Libraries/cBuffer
lib_deps=file:///home/norman/SourceCode/Libraries/AVRusart
I can even zip up the source and header files in each of those libraries to save space, and get PlatformIO to unzip them for me:
lib_deps=file:///home/norman/SourceCode/Libraries/AVRusart/AVRusart.zip.And, as I’m on Linux, I’m most likely to have a tarred up and compressed source file.
lib_deps=file:///home/norman/SourceCode/Libraries/AVRusart/AVRusart.tar.gz.Assuming lib_deps=servo, then the pio lib install command will find the best version of the Servo library, and copy the source to <PROJECT_HOME>/.pio/libdeps/<ENVIRONMENT>/<LIBRARY_NAME>/
For my Uno, and the Servo library, that would be: /home/norman/SourceCode/PlatformIO/PIO_Servo/.pio/libdeps/uno/Servo/.
Under that directory, I would (can!) see the following files and directories:
keywords.txt the file which tells the Arduino IDE how to colourise keywords for this library.library.properties another Arduino IDE file for the library manager.README.adoc contains brief details about the library, and how it is licenced.examples/ where the example sketches can be found – examples/Knob and examples/Sweep.src/ where the source file(s) for the Servo library can be found for various frameworks. The header file Servo.h lives in src/. I have the following sub-directories where appropriate versions of the Servo library files live:
src/avr/src/mbed/src/megaavr/src/ntf52/src/sam/src/samd/src/stm32f4/When you compile a project, any library sources will also be compiled into <PROJECT_HOME>/.pio/build/<ENVIRONMENT>/libnnnn<LIBRARY_NAME>/<FRAMEWORK_NAME> which in my example is: /home/norman/SourceCode/PlatformIO/PIO_Servo/.pio/build/uno//lib506/Servo/
Note: I have no idea where the lib506 comes from!
I never, manually download a library and install it somewhere. I let PlatformIO do all the hard work of finding and installing the libraries for me.
I don’t use global libraries, each project gets its own install, if necessary, locally.
Lib_deps does all the hard work for me, I don’t even have to think about it.
Have fun!
First of all, thank you very much for this.
This is automatic, no? I don’t see this happening?
I’m not typing anything in. I saw the place where you select commands from a drop-down, where Intellisense rebuild lives. But I’m just using the GUI.
I’ll want to use commands eventually. ESP32 has a catalog of AT commands, and I’ll use esp-idf at least once. I think I’ll need to use it when I use the ESP Upload Tool to upload more than one program.
I don’t want to link. I want the files to be located under PIO’s umbrella.
I’m going to use the first good program as an excuse to write to a Tiny85, and I’ll want to optimize everything in that folder as a movable unit. I’d rather not introduce links to third-party/third application objects only to remove them later. I want the compiler to travel a short ‘distance.’
I’ll try lib_deps first. If what you say about lib_deps is true, I’ll be very happy. I really want to be wrestling with my C++ literacy.
And I just use the name of the library with no quotes, nothing?
But for stuff I want to build for real, I’l put them right into the SRC folder like you do. Since that’s the first folder the compiler reads, that’s where I want all the files. It will scan empty folders after that.
If it’s looking for the /include folder, I won’t delete the empty folder.
And versions- I was worried about that. I’ve only used a few sites as sources for libraries (GitHub, https://www.arduinolibraries.info/), and it SEEMS like these two should offer the latest versions first. I know PIO just updated, and it’s good about library and platform updates. My stored libraries will be the weak link. I’m sure lots of them are outdated.
So PIO sees
lib_ deps= Tone32
and it goes online to find the latest verion?
How can I then go download that latest version chosen by PIO?
Is it identified in the log text during compile in a way I can read?
