+
+// Example for GPIO testing and bit banging.
+//
+// This example was originally designed to test the 11 bit wide front panel
+// GPIO on the X300 series and has since been adapted to work with any GPIO
+// bank on any USRP and provide optional bit banging. Please excuse the
+// clutter. Also, there is no current way to detect the width of the
+// specified GPIO bank, so the user must specify the width with the --bits
+// flag if more than 11 bits.
+//
+// GPIO Testing:
+// For testing, GPIO bits are set as follows:
+// GPIO[0] = ATR output 1 at idle
+// GPIO[1] = ATR output 1 during RX
+// GPIO[2] = ATR output 1 during TX
+// GPIO[3] = ATR output 1 during full duplex
+// GPIO[4] = output
+// GPIO[n:5] = input (all other pins)
+// The testing cycles through idle, TX, RX, and full duplex, dwelling on each
+// test case (default 2 seconds), and then comparing the readback register with
+// the expected values of the outputs for verification. The values of all GPIO
+// registers are displayed at the end of each test case. Outputs can be
+// physically looped back to inputs to manually verify the inputs.
+//
+// GPIO Bit Banging:
+// GPIO banks have the standard registers of DDR for data direction and OUT
+// for output values. Users can bit bang the GPIO bits by using this example
+// with the --bitbang flag and specifying the --ddr and --out flags to set the
+// values of the corresponding registers. The READBACK register is
+// continuously read for the duration of the dwell time (default 2 seconds) so
+// users can monitor changes on the inputs.
+//
+// Automatic Transmit/Receive (ATR):
+// In addition to the standard DDR and OUT registers, the GPIO banks also
+// have ATR (Automatic Transmit/Receive) control registers that allow the
+// GPIO pins to be automatically set to specific values when the USRP is
+// idle, transmitting, receiving, or operating in full duplex mode. The
+// description of these registers is below:
+// CTRL - Control (0=manual, 1=ATR)
+// ATR_0X - Values to be set when idle
+// ATR_RX - Output values to be set when receiving
+// ATR_TX - Output values to be set when transmitting
+// ATR_XX - Output values to be set when operating in full duplex
+// This code below contains examples of setting all these registers. On
+// devices with multiple radios, the ATR for the front panel GPIO is driven
+// by the state of the first radio (0 or A).
+//
+// The UHD API
+// The multi_usrp::set_gpio_attr() method is the UHD API for configuring and
+// controlling the GPIO banks. The parameters to the method are:
+// bank - the name of the GPIO bank (typically "FP0" for front panel GPIO,
+// "TX<n>" for TX daughter card GPIO, or
+// "RX<n>" for RX daughter card GPIO)
+// attr - attribute (register) to change ("DDR", "OUT", "CTRL", "ATR_0X",
+// "ATR_RX", "ATR_TX", "ATR_XX")
+// value - the value to be set
+// mask - a mask indicating which bits in the specified attribute register are
+// to be changed (default is all bits).
