mraa_raspberry_pi_pinmap.h

/* Raspberry Pi Pin Mappings for NB Board LP 0 Only!!!!!
*
* revision 0.1 - Initial revision with proposed mappings
* revision 0.2 - Added raspberry Pi version and set I2CP bus for private bus (EEPROM and Display)
* revision 1.0 - New hardware has pin shift on SPI CE0 and CE1
*
* GP2 to GP9 go to Arduino Connector
* GP8 Connected to Button #1
* GP9 Connected to Button #2
* GP10 Connected to Button #3
* GP11 Connected to Button #4
*
* SPI_CS0 only goes to ADC 3208
* SPI control signals goto user connectors gated by SPI_CS0
*
* I2CP bus goes to EEPROM and Display - Consider as Private Bus
*
* I2C1 bus goes to Arduino Connector and user connectors
