48+ Arduino Mega 2560 I2C Pins
Pictures. On your mega2560 are 5 ground pins (effectively equivalent because they are connected). I have an arduino mega 2560 board, but not as connect my board to a circuit ds013 (real time clock), what are the pin i2c?

They are circled on the photo below, and marked gnd on the board. 50, 51, 52 (and 53 as cs). On your mega2560 are 5 ground pins (effectively equivalent because they are connected).
They are circled on the photo below, and marked gnd on the board.
Although i can still use them with port manipulation, i would like to manually add them to pins_arduino.h so i can accomplish a better manipulation using arrays. The arduino mega 2560 is a replacement of the old arduino mega, and so in general reference, it will be called without the '2560' extension. They are circled on the photo below, and marked gnd on the board. The arduino mega 2560 is a microcontroller board based on the atmega2560 (datasheet).
