Hello.

I have just received a photon and a shield shield and I would like to plug an paper display from seeedstudio.  
[epaper shield](http://www.seeedstudio.com/depot/Small-epaper-Shield-V2-p-2462.html?cPath=34_82)  
[2.7 epaper](http://www.seeedstudio.com/depot/27-ePaper-Panel-p-1596.html?cPath=34_82)

I am having a hard time to figure out the arduino/photon pin mapping.

here is the mapping I use on a arduino UNO

Arduino E-paper  
D2 M\_EPD\_PANEL\_ON  
D3 M\_EPD\_BORDER  
D4 M\_/SD\_CS  
D5 M\_EPD\_PWM  
D6 M\_EPD\_/RESET  
D7 M\_EPD\_BUSY  
D8 M\_EPD\_DISCHARGE  
D9 M\_/WORD\_STOCK\_CS  
D10 M\_/EPD\_CS  
ICSP PORT M\_MOSI , M\_SCK , M\_MISO  
A0 M\_TEMP\_SEN  
A1 M\_OE123  
A2 M\_CKV  
A3 M\_STV\_IN  
3.3V M\_VCC\_3V3  
5V M\_VCC\_5V

if possible, what would it be for a photon?

Thank you for your help.

regards.
