Hello. I am trying to use the small e-paper shield (http://www.seeedstudio.com/wiki/Small_e-Paper_Shield) with a non-arduino development board (mbed platform). I want to manually connect the the shield’s pins to my board’s pins, but I have no idea which pins on the shield do what. Is this documented somewhere? I am looking for a mapping somewhere along the lines of: “D0: PANEL ON, D1: PWM, D2: SDA, D3: SCL, …” etc. (I made these numbers up, but you get the idea).
Thanks!
I got an answer from seeedstudio support, here it is for reference:
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
A0 <------> M_TEMP_SEN
A1 <------> M_OE123
A2 <------> M_CKV
A3 <------> M_STV_IN
5v <------> M_VCC_5V
3.3v <------> M_VCC_3V3
ICSP port <------> M_MOSI , M_SCK , M_MISO
great! 
Are above signals required to connect to the e-paper shield ?
While i checked the schematic and the product datasheet (2.0" e-Paper Panel seeedstudio.com/depot/20-ePa … -1595.html), i can not find above signals input to e-paper panel device. So, i think that these signals can be omitted to connect to the shield. But i can not make sure.
If you have a knowledge about it, please tell me.
Hi, those pin was reserve for a higher version of epaper, it’s useless yet.
Thanks a lot !
