Arduino libraries not working code#

My target AVR is Arduino Uno R3, the code used to work fine in a sketch before I decided to create a library out of it. print the decimal point on the 2nd digit ShiftOut (dataPin, clockPin, MSBFIRST, data) įor (int n = 0 n < 4 n++) digitalWrite (digitPins, HIGH) This can be due to: Library is not Installed (see previous pages in this guide) Wrong Folder Location Wrong Folder Name Wrong Library Name Library Dependencies Forgot to Shutdown the IDE See below for solutions to these problems. Void SegDispaly::setRegisterData (byte data) Run the following commands: Clear all classes. SegDisplay::SegDisplay (int a, int b, int c, int d):ĬlockPin (a), latchPin (b), dataPin (c), digitPins (d), digitBuffer () Custom Library Class Not Detected Make sure that the folder with the custom library is added to the MATLAB path. SegDisplay (int clockPin, int latchPin, int dataPin, int digitPins) Ĭonst byte digit = //seven segment digits in bits Select the main folder (it should have the library’s name) and move it to the libraries folder inside your sketchbook.

I have the library located in my sketch folder under the name 'SegDisplay': /home/me/sketchbook/libraries/Īnd here's the code: SegDisplay.h: #ifndef _SEVEN_SEG_H_ I wrote the code which seems to be fine to me except that it keeps complaining about the header file not found during compilation: /home/me/sketchbook/libraries/SegDisplay/SegDisplay.cpp:1:24: fatal error: SegDispaly.h: No such file or directory I have fair experience with C/C++ so I decided to have a go at writing my first simple Arduino library.
