Extension Errors

#1

I m trying to use LCD extension other than LCD I2C.

However when I try to upload, the same error occurs over and over…

The error shows

哪颇老 坷幅 惯积.

it looked like the libraries in mblock file in program file directory was malfunctioning, hence I tried changing the libraries from Arduino IDE, which works perfectly fine in Arduino IDE.

Anybody knows what is the problem with LiquidCrystal library?

#2

If the extension is nested exactly the same library liquidCristall as in the mBlock, then there are similar errors. Try to choose the option “Edit with arduinoIDE” and upload a sketch from the IDE. To eliminate such mistakes - it is better when writing libraries is used to rename library LiquidCristall and rename functions and procedures used in extension. In their extensions, I renamed all of this and no more similar errors.

#3

I have changed the name of the library (directory) in Arduino directory, though it seems this wasn’t the trick… Maybe I should go and try modifying the cpp and h file themselves, which I tried to avoid…grr… Anyway it is quite strange because other libraries that Arduino provides seem to work fine, such as servo.h but LiquidCrystal… BTW Thanks for the reply!

#4

Try rename files .cpp and .h in folder “src” of extension and change it names in .s2e file (in “inc” structure).
