= Gateworks Linux Example Test Commands =
Following is a list of commands that are available in the BSP from Gateworks that can be used in order to test the functionality of the product. Users can use these commands to further the functionality of there application.


[=#pci]
== PCI ==
See also:
 * [wiki:newport/PCIe]
 * [wiki:ventana/PCIe]

=== Find available devices on the PCI Bus ===
{{{#!bash
lspci -v
}}}

== USB ==
=== Find available devices on the USB Bus ===
{{{#!bash
lsusb -v
}}}


[=#rtc]
== RTC ==
=== Read Time from RTC ===
{{{#!bash
hwclock -r
}}}

=== Write current Time to RTC ===
{{{#!bash
hwclock -w
}}}


[=#hwmon]
== HWMON ==
=== Read Voltage ===
Different voltages can be read from the board, just change in0 to any of in0 - in12[[BR]]
The voltages read are current voltage * 1000
{{{#!bash
cat /sys/class/hwmon/hwmon0/device/in0_label
cat /sys/class/hwmon/hwmon0/device/in0_input
}}}

=== Read Temperature ===
The temp read is current temp * 10
{{{#!bash
cat /sys/class/hwmon/hwmon0/device/temp0_input
}}}

=== Set Fan Setpoint ===
The fan controller has 5 setpoints ranging from 50% on to 100% on, corresponding with fan0_point0 (50%) to fan0_poing5 (100%)
=== Read Current Setpoint ===
The setpoint read is current setpoint * 10
{{{#!bash
cat /sys/class/hwmon/hwmon0/device/fan0_point0
}}}
=== Write new Setpoint ===
Value to write is new temperatore * 10
{{{
echo 450 > /sys/class/hwmon/hwmon0/device/fan0_point0
}}}


[=#gpio]
== GPIO ==

See also:
 * [wiki:gpio]
 * [wiki:OpenWrt/gpio]

=== Read GPIO ===
See a list of currentl used GPIO's:
{{{#!bash
cat /sys/kernel/debug/gpio
}}}

=== Export A GPIO for user control ===
{{{#!bash
echo 8 > /sys/class/gpio/export # export gpio 8 which will get configured as an input
}}}

=== Set Direction of GPIO ===
{{{#!bash
echo out > /sys/class/gpio/gpio8/value # make gpio8 an output
echo in > /sys/class/gpio/gpio8/value # make gpio8 an input
}}}

=== Set Output of GPIO ===
{{{#!bash
echo 0 > /sys/class/gpio/gpio8/value # set gpio8 to logic low
echo 1 > /sys/class/gpio/gpio8/value # set gpio8 to logic high
}}}

=== Check GPIO ===
{{{#!bash
cat /sys/kernel/debug/gpio # see all gpio's
cat /sys/class/gpio/gpio8/value # see state of gpio8
}}}


[=#i2c]
== I2C ==
See also:
 * [wiki:I2C]
 * [wiki:linux/i2c]

=== Detect all available i2c devices ===
{{{#!bash
i2cdetect -f -y 0
}}}

=== Read i2c address ===
Where "x" is the device id, and "y" is the wanted address
{{{#!bash
i2cget -f -y 0 x y
}}}

=== Write i2c Address ===
Where "x" is the device id, and "y" is the wanted address to write and "z" is the value to write
{{{#!bash
i2cset -f -y 0 x y z
}}}


[=#kernel]
== Kernel Modules ==
See also:
 * [wiki:kernel]

=== Find modules loaded by kernel ===
{{{#!bash
lsmod
}}}
