Easy to set up, and works with the standard "LiquidCrystal_I2C" library.Contrast adjustable as described.2 cons:1) Red glow always from the top right and bottom left corners. Not bright, but there.2) A long message line continues from line 0 to line 2, ie. it skips a line, then goes back to line 1, and then to line 3. Not sure if this is fault of the hardware, or the library driver.To note - if I place the cursor on a specific line, it prints the specified message there OK.See code below and video.#include #include // initialize the library with the numbers of the interface pinsLiquidCrystal_I2C lcd(0x27,20,4); // set the LCD address to 0x27 for a 20 chars and 4 line displaychar message[] = "This is some long message that will end up scrolling on Line0 only";int previous = 0;int pos = 0;void setup(){ lcd.init(); //initialize the lcd lcd.backlight(); //open the backlight // Print a message to the LCD. lcd.print(message); delay(5000); lcd.clear();}void printLine(int refreshSeconds){ //Check if the current second since restart is a mod of refresh seconds, //if it is then update the display , it must also not equal the previously //stored value to prevent duplicate refreshes if((millis()/500) % refreshSeconds == 0 && previous != (millis()/500)) { previous = (millis()/500);//Store the current time we entered for comparison on the next cycle lcd.setCursor(0, 0);//Set our draw position , set second param to 0 to use the top line char lcdTop[20];//Create a char array to store the text for the line int copySize = 20; // What is the size of our screen , this could probably be moved outside the loop but its more dynamic like this if(strlen(message) < 20) { //if the message is bigger than the current buffer use its length instead; copySize = strlen(message); } //Store the current position temporarily and invert its sign if its negative since we are going in reverse int tempPos = pos; if(tempPos < 0) { tempPos = -(tempPos); } //Build the lcd text by copying the required text out of our template message variable memcpy(&lcdTop[0],&message[tempPos],copySize); lcd.print(lcdTop);//Print it from position 0 //Increase the current position and check if the position + 20 (screen size) would be larger than the message length , if it is go in reverse by inverting the sign. pos += 1; if(pos +20 >= strlen(message)) { pos = -(pos); } }}void loop(){ printLine(1); // Original program line lcd.setCursor(0,1); lcd.print("This is Line1 msg"); delay(250); lcd.setCursor(0,2); lcd.print("This is Line2 msg"); delay(250); lcd.setCursor(0,3); lcd.print("This is Line3 msg"); delay(250); lcd.clear(); }
