Way too sick of unreliable library stuff

5

Morning Joe,

I have your project here, many thanks. Seeing your code etc has shown the problem.

TL;DR

I managed to get it to compile on an Uno, in only two compilation attempts.

In summary of your problems, and as pointed out many times previously:

  • You have a pile of crud in lib.
  • You are #including the wrong headers, they are local not system headers, use double quotes not angle brackets;
  • You have a pile of crud in lib_deps - agreed, you just copied the ES project over and renamed it to uno.
  • There appears to be a problem with the fonts library, I cannot use it or download it (via lib_deps) so I had to remove it.
  • Adafruit GFX doesn’t seem to be available for linux_x86_64, but then it installs anyway. Interesting!
  • I cleaned out the potential crud in .pio.

It now compiles every time, it’s as happy as a piglet in brown stuff. :rofl:

However, this project will not work on an Uno for one main reason, the Uno only has a single channel for tone() - it cannot do more than one note at a time.

I think you have been corrupted by the Arduino IDE in that:

  • You appear to confuse a header file with an actual library, they are not (always) the same thing.
  • You may be confused when `#include’ is used as to when to use system headers and when to use local ones.
  • Also, stop putting stuff in lib - unless you write it yourself, say a class header and implementation file.

In addition, You have far too many threads open and appear to be missing responses to your questions on other threads, then you start another. Please, slow down, take your time, and read the replies. Thanks.

HTH

Right, gory details follow of what I had to do to compile the Uno version. as I said, it won’t run, but it will compile, each and every time.

In platformio.ini:

  • Remove Arduino from lib_deps;
  • Remove Wire from lib_deps;
  • Remove Tone32 from lib_deps;
  • Change all Adafruit_xxx to Adafruit xxx.

In lib Directory:

  • Deleted everything, from lib.

In .pio Directory:

  • Deleted build;
  • Deleted libdeps.

First Compile

The following is the extracted good news, and some bad!

    env.SConscript("$BUILD_SCRIPT")
  Etc etc etc

So, by removing all the crud (technical Term) you had dumped into lib, the libraries were correctly installed.

OK, I’ll give you a problem in the fonts library, not sure why that’s needed though.

Back in platformio.ini:

  • Removed Fonts/FreeSerif9pt7b from lib_deps.

In src/main.cpp:

  • Removed #include <Tone32.h> line.
  • Removed #include <Fonts/FreeSerif9pt7b.h> line.

These are not system headers, they are local headers, DO NOT wrap them in ‘<’ and ‘>’ they should be in double quotes. The code now looks like:

#include "Arduino.h"
#include "Time.h"
#include "Wire.h"
#include "Adafruit_GFX.h"
#include "Adafruit_SSD1306.h"
  • Commented out the line display.setFont(&FreeSerif9pt7b); as we are not able to use the fonts.

Second Compile:

It worked!
