![]() 51, 50 and 52, you could try those, maybe your there is something wrong with your ICSP header on the Mega.į.Y. One other thing, I found out in the pins_arduino.h file that for the Mega not pins 11, 12 and 13 are to be used, but resp. The following boards use the same ATmega2560 processor and have more or less similar pinout and functionality: The Arduino Mega 2560 Rev3 - This board is an upgrade to the original Arduino Mega and features the same ATmega2560 microcontroller as the Arduino Mega ADK. Reopen the Arduino IDE, you should see the ATtiny85 in the Tools > Board menu. Copy the folder to the Arduino IDEs Hardware folder. ![]() The target board can also be powered from the. To program the ATtiny85 using the Arduino ISP you must first add ATtiny85 support to the Arduino environment: Download attiny4585.zip. Connect the Arduino ISP to your computer with a micro USB cable, and connect the target board to a power source (USB cable or with the power jack). Hello, I am trying to use my Arduino Mega Pro (with USB-serial converter) as an ISP programmer to flash an Arduino Pro Mini (3.3V, 8MHZ, Atmega328p). Regarding the USB connect error, I can imagine that the nano is not able to power the mega, but as I am a rookie too, that's just a wild guess. Plug the Arduino ISP on the 6-pin ICSP connector of the Arduino board you want to program, as shown in the picture. Not the most glorious fix, I had forgotten to solder the RST pin on the Mega Pro. Each pin can provide or receive a maximum of 40 mA and has an internal pull-up resistor (disconnected by default) of 20-50 kOhms. I think the ISP software (are you using the one from examples?) is updated too. Each of the 50 digital pins on the Arduino Mega ADK can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. I see your topic is quite old, the first thing I would definitely do is upgrade to Arduino 021, I think only after 020 there is official support for the Mega2560. ![]() A fuller explanation of he ICSP is here: Arduino Mega 2560 digital pins 50-52 / ICSP pins - Microcontrollers - Arduino Forum - found with a quick search so tthere may be other explanation more suited to you. Hi, I saw you make a reference to this topic in. The Ethernet card is connected via the ICSP where pins 50, 51, 52 are also duplicated. ![]()
