Although most computers provide their own internal protection, the fuse provides an extra layer of protection. The Mega 2560 has a resettable polyfuse that protects your computer's USB ports from shorts and overcurrent. See this user-contributed tutorial for more information. Or you can use the ISP header with an external programmer (overwriting the DFU bootloader). You can then use Atmel's FLIP software (Windows) or the DFU programmer (Mac OS X and Linux) to load a new firmware.

On Rev2 or later boards: there is a resistor that pulling the 8U2/16U2 HWB line to ground, making it easier to put into DFU mode.

On Rev1 boards: connecting the solder jumper on the back of the board (near the map of Italy) and then resetting the 8U2.

The ATmega16U2/8U2 is loaded with a DFU bootloader, which can be activated by: The ATmega16U2 (or 8U2 in the rev1 and rev2 boards) firmware source code is available in the Arduino repository.

You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar see these instructions for details. It communicates using the original STK500 protocol ( reference, C header files). The ATmega2560 on the Mega 2560 comes preprogrammed with a bootloader that allows you to upload new code to it without the use of an external hardware programmer. For details, see the reference and tutorials.

#Arduino mega 2560 ss pin update#

The Mega 2560 is an update to the Arduino Mega, which it replaces. The Mega 2560 board is compatible with most shields designed for the Uno and the former boards Duemilanove or Diecimila. It contains everything needed to support the microcontroller simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

My main question is where would I find chipSelect being defined in the libraries.The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. I would how ever like to do it at the same time as redefining chipSelect, but would need to know what const ints to change, any ideas on where chipSelect would have been defined in either the SD libraries or the SPI libraries.

Static const uint8_t MISO = PIN_SPI_MISO Static const uint8_t MOSI = PIN_SPI_MOSI In the pins_arduino file for the mega I could just: #define PIN_SPI_SS (10) // rather than 53 Plenty of SS MOSI MISO SCLK or variations of that with _PIN H files for SD, Sd2, SPI as well as the pins_arduino file for the mega I can not find any reference to 'chipSelect'. This makes sense on the surface how ever digging through the. Using the example code Cardinfo, I can set CS to be 10. On the mega these would normally be mapped to 53 51 50 and 52 I want to use pins 10-13 for CS DI D0 and SCK respectively. I am trying to get an SD card reader to work with a mega2560.
