I am having hard time understanding the Raspberry PI 2 Model B's PINOUT. I have RTC Module I want to use with my PI, but no matter what I do there seems to be NO response at all from RTC. I even scoped the pinout's output. None of their signals change state when I try to write into RTC. Here is the wiring information that I got from a website Hobbytronics
VCC - 3.3V GND - GND (CLK) SCLK- GPIO#21 (DAT) IO - GPIO#18 (RST) CE - GPIO#17
For the life of me, I simply can't get anything toggling either. So, could someone please tell me where these PINS are located physically on the Board itself for PI 2 Model B.
