// display next character of message
drawChar(120, 1, message[count % (sizeof(message) - 1)], 1, false);
count = (count + 1);
// DISPLAY SCROLL Rate set at delay
// move the text 7 pixels (not 8 because it looks better) to the left
for (byte i = 0; i < 10; i++) { // character spacing
delay(50); // delay between scrolls
moveLeft(1, 2, 15); // column spacing,?,?
};
};
any idea....
but I do not I can find nowhere; could someone or the author himself share the link from that library? I would be very grateful
