4/11/2024 0 Comments Arduino mega 2560 vcc pin![]() Be sure to use the freetronics brand and not some other like FTDI, because they will not work. In this circuit the Freetronics USB Serial Adapter (FUSA) takes the place of the Arduino Mega from the previous circuit, and transfers the program from the Arduino IDE to the atmega 2560. With the bootloader installed you can start building the circuit for a test program (see figure on right). Type ‘C’ when ready to continue with another chip … You should see the following in the serial monitor: Erasing chip … Once you see the above, type “G” into the serial monitor to commence programming. Type ‘G’ to program the chip with the bootloader … Now upload the bootloader sketch and wait to see the following inside the serial monitor: Atmega chip programmer. You should now have a circuit that looks like the one depicted in the figure below. The pin assignments for the atmega 2560 and Arduino Mega are illustrated in the figure above. Connect the 16.000 MHz Crystal to the atmega, via a breadboard, with the left leg of the crystal connected to XTAL2 (at pin 33 on the atmega) and the right leg of the crystal connected to XTAL1 (at pin 34 on the atmega).Arduino Mega pin +5V for +5V on atmega pin 31.Arduino Mega pin Gnd for Gnd on atmega pin 32. ![]()
