You can do a find and replace of all calls if it's an existing sketch - (just make sure you don't replace the definition and the matrix.begin) - - If the sketch makes use of MATRIX_HEIGHT or MATRIX_WIDTH, these will need to be replaced with the width and height - of your virtual screen. Either make new defines and use that, or you can use virtualDisp.width() or .height() +2) In the sketch: + +- Set values for NUM_ROWS, NUM_COLS, PANEL_RES_X, PANEL_RES_Y.
