Hello.
This is my first post and I am not good at speaking English.
Please excuse.

Well, I want to use Arduino library while using Arduino as ESP-IDF component.
I want to use Adafruit-Fingerprint-Sensor-Library(https://github.com/adafruit/Adafruit-Fi ... or-Library)

I added the file(Adafruit-Fingerprint-Sensor-Library) to C:\msys32\home\user-name\esp\hello_world\components\arduino\libraries
and I edited CMakeLists.txt(C:\msys32\home\user-name\esp\hello_world\components\arduino)

Code: Select all

set(LIBRARY_SRCS
  libraries/ArduinoOTA/src/ArduinoOTA.cpp

↓

Code: Select all

set(LIBRARY_SRCS
  libraries/Adafruit-Fingerprint-Sensor-Library/Adafruit_Fingerprint.cpp
  libraries/ArduinoOTA/src/ArduinoOTA.cpp

Code: Select all

set(COMPONENT_ADD_INCLUDEDIRS
  variants/esp32/
  cores/esp32/
  libraries/ArduinoOTA/src

↓

Code: Select all

set(COMPONENT_ADD_INCLUDEDIRS
  variants/esp32/
  cores/esp32/
  libraries/Adafruit-Fingerprint-Sensor-Library
  libraries/ArduinoOTA/src

Then I did "make flash" but it did not succeed.

Thank you for taking the time to read my post.
Please help me.

Hi,
did you read this post about using arduino as component?
https://github.com/espressif/arduino-es ... mponent.md

Also my suggestion is to use GNU make in this case, since arduino is still based on esp-idf v3.x.

Thank you for the reply, chegewara.

I read the post and downgraded esp-idf.
However it didn't go well.

I don't know about build system.
I don't know even whether GNU make or C make, too.

If you have time, please tell me more.

This problem was solved by using another library.

Which library did you use?
I am having the same problem and do not seem to find a workaround

Hi Jimas,

We've had good results by using this fork of Espressif's Arduino core: https://github.com/summivox/arduino-esp32
The instructions for using it as a component can be found here: https://github.com/summivox/arduino-esp ... mponent.md
