-Galileo Gen 2 - Rev H {#galileorevh}
-=====================
-
-Galileo is a microcontroller board based on the Intel(R) Quark(TM) SoC X1000
-Application Processor, a 32-bit Intel Pentium-class system on a chip.
-
-The Gen 2 board has the following limitations in libmraa:
-
-- i2c is set at 400Khz speed cannot be changed without reloading kernel module,
- the driver is intel_qrk_gip_i2c and the parameter is i2c_std_mode which must
- be set to 1 in order to set the i2c bus speed to 100Khz
-- i2c bus is shared with multiple devices in kernel space, scanning it usually
- fails
-- pwm period is set globally for all pwm channels, when changed this will halt
- all pwm channels
-- adc kernel module will return 12bit number but the ADC itself only has an
- accuracy of 10bits.
-- AIO pins are treated as 0-5 in mraa_aio_init() but as 14-19 for everything
- else. Therefore use mraa_gpio_init(14) to use A0 as a Gpio

-Uart 1 on gen2
---------------
-
-Uart 1 is connected to the FTDI header and the linux console. It's also
-possible to use it from A2(Rx)/A3(Tx). However mraa does not support this
-directly so you need to enable the muxing manually. Here is an example of how
-this is done, this was tested using an FTDI 3.3V TTL cable:
-
-$ systemctl stop serial-getty@ttyS1.service
-
-$ python
->>> # Configure the Muxes for Uart1 on Aio2/3
->>> import mraa as m
->>> p77 = m.Gpio(77, False, True)
->>> p76 = m.Gpio(76, False, True)
->>> p16 = m.Gpio(16, False, True)
->>> p17 = m.Gpio(17, False, True)
->>> p77.write(1)
->>> p76.write(1)
->>> p16.dir(m.DIR_OUT)
->>> p16.write(0)
->>> p17.dir(m.DIR_OUT)
->>> p17.write(1)
-
->>> # For Rx to work correctly switch the level shifter
->>> p34 = m.Gpio(34, False, True)
->>> p34.dir(m.DIR_OUT)
->>> p34.write(1)
-
->>> # Use the uart
->>> x = m.Uart(1)
->>> x.setBaudRate(115200)
->>> x.writeStr('hello')
->>> x.read(5)
-bytearray(b'dsds\n')
