/**
 * @example    rc_bind_dsm
 *
 * routine to put a DSM2/DSMX satellite receiver into pairing mode
 *
 * DSM satellite receivers are put into bind mode by sending them a sequence of
 * pulses right after it receives power and starts up. This program puts the
 * normally UART signal pin into GPIO pulldown mode temporarily, detects when
 * the user unplugs and plugs back in the receiver, then sends the binding
 * pulses.
 *
 * the number of pulses dictates the mode the satellite receiver will request
 * the transmitter to use. The transmitter may bind but use a different mode. I
 * suggest configuring your radio to use DSMX 11ms fast mode if it allows that.
 *
 * 2048 & 1024 indicates 10 or 11 bit resolution. 11ms & 22ms indicates the time
 * period between the transmitter sending frames. 11ms is required for
 * transmitters with 8 or more channels.
 *
 * Testing done with DX7s, DX6i, DX8, and Orange T-SIX
 *
 * Table of Bind Modes
 *
 * - pulses      mode
 * - 3      DSM2 1024/22ms
 * - 5      DSM2 2048/11ms
 * - 7      DSMX 1024/22ms:
 * - 9      DSMx 2048/11ms:
