   1 Intel Edison                            {#edison}
   2 =============
   3
   4 Edison is a dual core Silvermont Atom clocked at 500MHz. The Edison
   5 also features 4GB of storage, 1GB ram and onboard wifi and bluetooth.
   6
   7 Currently Supported boards:
   8 - Intel Arduino board
   9 - Intel breakout board
  10
  11 UART
  12 ----
  13 On both the Arduino board and the breakout board, The avaible UART interface is on /dev/ttyMFD1
  14
  15 Intel Arduino board
  16 -------------------
  17 The Edison used with the Arduino board has the following limitations
  18 in libmraa:
  19
  20 - i2c is exposed on i2c-6, therfore you must use bus 6 and not bus 0
  21 - PWM avaible on default swizzler postions. (3,5,6,9)
  22 - SPI exposed is also used for the ADC. Try not to use your own CS.
  23 - ADC kernel module will return 12bit number but the ADC itself only has an
  24   accuracy of 10bits. This ADC is only included on the arduino board.
  25
  26 Intel breakout board
  27 --------------------
  28
  29 - Both I2C buses are avaible 1 & 6
  30 - IO on the miniboard is 1.8V
