ICSP Header Pins & DS3234

Projects Programming
1

I am using the DS3234 Library from here

http://www.henningkarlsen.com/electronics/library.php?id=71

And the HW from here, with no battery

I have an Arduino Mega 2560, connected to a 3.2" Sainsmart TFT, which is using the Pins

static const uint8_t SS = 53;
static const uint8_t MOSI = 51;
static const uint8_t MISO = 50;
static const uint8_t SCK = 52;

And so I connected my RTC to the ICSP pins
// ICSP header pinout: +---+---+
// 1 - MISO | X | X | 2 - Vcc
// +---+---+
// 3 - SCLK | X | X | 4 - MOSI
// +---+---+
// 5 - Reset | X | X | 6 - GND
// +---+---+

MISO -- MISO
SCLK -- CLK
MOSI -- MOSI
SS = Pin 9

VCC and GND connect to the Arduino Pin VCC and GND and not the ICSP header. When I run the example code, I do not see any time. Can I run from the pins and the ICSP at the same time?

Thanks.

I just tried on an UNO, just that and nothing else and still no luck. Changed pins to

SS = D8
MOSI = D11
MISO = D12
SCLK = D13
VCC = 3.3
GND = GND

Does it work without a battery?
