![]() ![]() A 1-to-1 replica of the Arduino Uno tutorials unfortunately does not work.īelow I’ve graphed the the wiring for you. When cabling you must be a bit careful because of some other port assignment of the Arduino Megas. How to wire Arduino Mega 2560 and enc28j60 ethernet shield However, for the Arduino Mega 2560, I could not find anything useful information, so I would like to address briefly below on the intricacies of this combination. Sure, the wiring and the library (the original ethernet library isn’t compatible), are not quite as comfortable as those of the original ethernet shields, but you can also save 30$ and more compared to the official ethernet shield.įor the Arduino Uno, there is already a handful of useful articles, which refers to the enc28j60 and Ethercard library. These are the low-cost ethernet shields, which are available for example at eBay for less then 5$. No products found.The enc28j60 Ethernet adapter should be known to one or the other of you, who has ever tinkered with an Arduino. In particular, for the Arduino Mega 2560 and how these can be used in combination with the enc28j60 ethernet adapters. I have no clue about that other than what I just told you.Today it is time to talk again about one of my favourite gadgets – my Arduinos. You can ask Crossroads what to do but you may need to find a way to connect to the pin on the USBasp that performs a similar (SS) function. I don't know anything about the USBasp but I know that even though it is only used ONCE with a 50ms delay in the INIT routine it is apparently important because it will not init the SPI without it. following delays may not work on all targets. Look at this code in ArduinoISP sketch #include "pins_arduino.h" ![]() Your mega already has a bootloader so you don't need that option. (RESET), I cannot program the chip, including the BURN BOOTLOADER option I need to put a bootloader in the chip. I really don't know why it is necessary but if I don't connect a jumper wire from my UNO pin -10 (SS) to the attiny85 -pin-1 In the ArduinoISP sketch the pin is called SLAVE RESET. I can't help you with your USBasp but for what it is worth, I bought two TINYISP s from kickstarter and discovered that there was no connection from pin-1 of the ATtiny85 on the ATtinyISP to the 6 pin ICSP header, and as you may or may not know, this is the wire connections from an UNO to program an ATtiny85.ĪTtiny Pin 2 to Arduino Pin 13 (or SCK of another programmer)ĪTtiny Pin 1 to Arduino Pin 12 (or MISO of another programmer)ĪTtiny Pin 0 to Arduino Pin 11 (or MOSI of another programmer)ĪTtiny Reset Pin to Arduino Pin 10 (SS) (or RESET of another programmer)Īttached is the wiring illustration that shows the SS pin of the UNO is actually connected to the RESET pin of the ATtiny85 but All I can find is the connector pinout which doesn't have an SS pin. I can't find any pinout documentation for your USBasp board. Any clue what I am missing? Still not getting any error messages, just a non responsive board.Īny suggestions why this method works for programming the arduino UNO but not the Mega?ĭo you see an "SS" (SPI CHIP SELECT) on the ICSP connector for the mega ?ĭo you have pin 53 connected to the SS PIN on the USBasp ?Ĭan ANY SPI interface work WITHOUT a chip select ? I have tried using the USBasp, Arduino UNO, and Arduino Mega as a programmer to write to a mega with no success. Here is the simple code I am uploading int led = 13 ĭigitalWrite(led, HIGH) // turn the LED on (HIGH is the voltage level)ĭigitalWrite(led, LOW) // turn the LED off by making the voltage LOW I get the same type of message when i upload to the UNO but in that case it actually works.Ĭompiling 'test' for 'Arduino Mega 2560 or Mega ADK'īinary sketch size: 1632 bytes (of a 258048 byte maximum) (0.2140123 secs) ![]() Below is the message I recieve when attempting to upload to the MEGA. The compiler says everything was successful but I cannot get the simple blink code to work. However, when I attempt to upload to the MEGA boards nothing happens. ![]() I am even able to upload code to the arduino UNO using this method with no problems via the arduino IDE or microsoft visual studio. I have gone through the required firmware dates to the USPasp and such. Hello all, I am seeking help with programming an arduino MEGA via the ICSP using a USBasp. ![]()
