Problem about analog electrical conductivity sensor when using kit STM32F103C8

Hello everyone,
I'm having a trouble with using analog electrical conductivity sensor when using STM32F103C8 (20k RAM. 64k Flash), program with Arduino IDE. I copied library from https://github.com/DFRobot/DFRobot_EC but it didn't work with this error:

c:/users/dell/appdata/local/arduino15/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/../lib/gcc/arm-none-eabi/4.8.3/../../../../arm-none-eabi/bin/ld.exe: C:\Users\DELL\AppData\Local\Temp\arduino_build_86827/DFRobot_EC_Test.ino.elf section .text' will not fit in region rom'
c:/users/dell/appdata/local/arduino15/packages/arduino/tools/arm-none-eabi-gcc/4.8.3-2014q1/bin/../lib/gcc/arm-none-eabi/4.8.3/../../../../arm-none-eabi/bin/ld.exe: region `rom' overflowed by 15752 bytes
collect2.exe: error: ld returned 1 exit status
exit status 1

I think this problem maybe the library using for kit Arduino. But I dont know how to adjust this library to be suit for kit STM32F103C8.
Please help me :frowning:

Maybe it is better to seek help in the STM32 forum:

https://www.stm32duino.com/

Or, It may be best to seek help from the library repository.

(The Arduino forum is usually able to help with more general issues or native board issues. Note that this library does not report that it supports STM32, maybe there is another one that supports it.)
