May I jump in here with a related question? I have been playing with a TM1638 LED display (8 characters 7 segments using I2C) and encountered the sendData function. I have searched the header files from the library, the .cpp files, even did a search of my whole Arduino directory for ". containing sendData". I have been unable to find the body of the function, where the actual code resides. The prototype is in the header files, the class is instantiated in the .cpp files but nowhere could I find the function. The code compiles and uploads and runs with no problems; I just can't find what exactly it is doing. Since you seem to be dealing with the same function I hope you could point me to where I could study the function so I could understand what it is doing in more than a general sense like "is sends the data that has been readied."
Any help would be appreciated.
Thanks
