[Solved] Problem trying to use ESPWheel library

Projects Programming
1

Hello, I was trying to use this library (https://drive.google.com/file/d/1CrJxms5pFNL6whzVFgNIWS55XVVezBFZ/view) and I found some errors when trying to compile the proyect included with the file. I tried using the latest version of the Arduino IDE, however that didn't work because the library is intended for Arduino 1.0.5 so I used the Arduino 1.0.5 r2 downloaded from here (Google Code Archive - Long-term storage for Google Code Project Hosting.) (because the official previous IDE versions page didn't allow me to download it). I followed the installation instructions from the "Readme" file inside of the zip, (importing the library from the IDE does not work, it places all the zip files inside of C:/Users/USER/Documents/Arduino/libraries) and placed the RFRWheel folder from ESP_WHEEL inside C:/Users/USER/Documents/Arduino where the sketches are. I placed the libraries (from ESP_WHEEL/arduino-1.0.5/libraries) in C:/ProgramFiles(x86)/Arduino/libraries and the content from ESP_WHEEL/arduino-1.0.5 inside C:/ProgramFiles(x86)/Arduino, however I realized that inside ESP_WHEEL/arduino-1.0.5/hardware/arduino/cores there is a folder called "arduino_gs" which has the same file names of the "arduino" folder inside C:/ProgramFiles(x86)/Arduino/hardware/arduino/cores but with some additions such as inside of Arduino.h it defines class types such as "u8" and many other things, at first I did not know this and when I tried to compile the RFRWheel proyect I got the following error message when trying to compile:

I have no clue where to go from here. Thanks in advance.

Please post a link to where you found this project. That may provide us with valuable information about how to use it.

OK, please follow these instructions:

  1. First of all, we need to make a fresh start so that your previous attempts don't trip us up. Uninstall your installation of Arduino IDE 1.0.5.
  2. Download Arduino IDE 1.0.6 from this link: https://downloads.arduino.cc/arduino-1.0.6-windows.zip
    Even if the project has the format for use with Arduino IDE 1.0.x, you might as well have a slightly less antiquated version. This is why I picked 1.0.6 instead of 1.0.5.
  3. Unzip the downloaded file.
    This is the .zip version of the Arduino IDE. It doesn't require installation, so it can coexist with a modern version of the IDE for your other projects.
    You can put it in any convenient location on your computer. From here on, I will refer to the location of it like this: <Arduino IDE installation folder>
  4. Download https://drive.google.com/file/d/1CrJxms5pFNL6whzVFgNIWS55XVVezBFZ/view
  5. Unzip the downloaded file.
    From here on, I will refer to the location of it like this: <ESP_WHEEL unzip folder>
  6. From the unzipped folder, copy this subfolder:
    <ESP_WHEEL unzip folder>\arduino-1.0.5\hardware\arduino\cores\arduino_gs
    to here:
    <Arduino IDE installation folder>\hardware\arduino\cores
  7. From the unzipped folder, copy all folders under this subfolder:
    <ESP_WHEEL unzip folder>\arduino-1.0.5\libraries
    to here:
    <Arduino IDE installation folder>\libraries
  8. Open this file in a text editor:
    <Arduino IDE installation folder>\hardware\arduino\boards.txt
  9. Paste this text at the end of the file:
    ##############################################################

leonardoffb.name=Arduino Leonardo (FFB HID)

leonardoffb.bootloader.high_fuses=0xd8
leonardoffb.bootloader.extended_fuses=0xcb

leonardoffb.build.vid=0x2341
leonardoffb.build.pid=0x8036
leonardoffb.build.core=arduino_gs
leonardoffb.build.variant=leonardo
  10. Double click on this file:
    <Arduino IDE installation folder>\arduino.exe
  11. Wait for the Arduino IDE to start up.
  12. Select File > Open from the Arduino IDE menus.
  13. In the "**Open an Arduino sketch..." dialog, select this file:
    <ESP_WHEEL unzip folder>\RFRWheel\RFRWheel.ino
  14. Click the Open button.
  15. Select Tools > Board > Arduino Leonardo (FFB HID) from the Arduino IDE menus.

Now try compiling the sketch again. The error should no longer occur.

Please note that, in general, you should never install things to the hardware or libraries subfolders of the Arduino IDE installation.

The reason is that all this will be lost every time you update to a new version of the Arduino IDE. My instructions do that because it is the way the "ESP_WHEEL" creator set it up (it was made at a time where that sort of foolishness was common practice) and I don't have the time right now to go through the changes that are needed to install it in a best practices manner.

Sorry I couldn't get back to you sooner, I tried what you instructed me and it worked, no errors at all. Thanks a lot!

You are welcome. I'm glad it is working now. Enjoy!
