    Sainsmart 3.2 inch TFT Touchscreen interface with Arduino

    Re: Sainsmart 3.2 TFT LCD touchscreen interface with Arduino mega 2560 board I have not studied or used the code so don't know. If you look at the code, there is a header file *.h, a C++ library file *.cpp and 2 arduino files - all these need to be appropriately renamed to be usable arduino...

    Sainsmart 3.2 inch TFT Touchscreen interface with Arduino

    Re: Sainsmart 3.2 TFT LCD touchscreen interface with Arduino mega 2560 board Here are the examples and library associated with them. EDAboard would not allow me to upload *.cpp, *.h or *.ino files, so you'll need to rename the files and librariy correctly.

    Eagle is being deliberately trashed

    When did Eagle become the simplest PCB package? I now use Kicad - every time I attempted using Eagle it was anything but intuitive or easy to use.

    How does a small company start making LED streetlight drivers?
