I'm have an Adafruit Data logger shield(P1141) plugged into a Arduino Uno board and I know that this data logger has a RTC (PCF8523). I also have a MPL3115A2 sensor which uses the Analog 4 &5.
The circuit is:
3.3V -> VCC (MPL3115A2)
GND -> GND (MPL3115A2)
A4 -> SDA (MPL3115A2)
A5 -> SCL (MPL3115A2)
SCK-> #13 (SPI)
MOSI-> #11 (SPI)
I also have a button battery for the RTC and a SD card.
The code works fine but it does not give me any time stamp. I found some information about it online but I have no idea what they are talking about: they have something called SS, CS, and CLK which I can not find on my board.
Are these related to the RTC ? and How can I make the connection with RTC so that I can see time on the SD card txt file?
Thank you in advance !
