   1 Intel Edison                            {#edison}
   2 =============
   3
   4 Intel(R) Edison is a dual core Silvermont Atom(TM) clocked at 500MHz. The
   5 Edison 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 - AIO pins are treated as 0-5 in mraa_aio_init() but as 14-19 for everything
  26   else. Therefore use mraa_gpio_init(14) to use A0 as a Gpio
  27
  28 Intel(R) breakout board
  29 -----------------------
  30
  31 - Both I2C buses are avaible 1 & 6
  32 - IO on the miniboard is 1.8V
