The display requires resisters: 220-470 ohm. Use bitRead to get a specific bit of a number. Loop through the number of bits, to get all the bits. lcd.setCursor(0,1); // set to first character bottom line for (int i=15; i>=0; i--) ...
MightyCore supports a variety of different clock frequencies. Select the microcontroller in the boards menu, then select the clock frequency.You will have to hit "Burn bootloader" in order to set the correct fuses and upload the correct bootloader. This also has to be done if you want to cha...
