6 Configuration commands - for Falcom STEPP

STEPPCONFIG VERSION 1.8.14
** X, Y, Z position Coordinates of user’s position in ECEF (meters). The
Earth-centered Earth-Fixed (ECEF) is a Cartesian
coordinate system with its origin located at the center of
the Earth. The coordinate system used by GPS to
describe 3-D location. For WGS-84 (World Geodetic
System 1984) reference ellipsoid. ECEF coordinated
have the Z-axis aligned with the Earth’s spin axis, The
X-axis through the insertion of the Prime meridian and
the Equator and the Y-axis is rotated 90 degrees East of
the X-axis about the Z-axis.

6.7.1 Convert the GPIO hexadecimal value to binarry format
In order to identify the status of provided GPIO states, you have to convert the
corresponding hexa value in the binary format. The schematic below shows the
structure of the GPIO protocol message converted from hexa value (4215) in
the binary format. The GPIO state consists of a 16 bit values (4 Bytes), where
the first 8 bits (0-7 bits, counting begin from right to left) inicate the outputs
state and the last 8 bits (8-15 bits) indicate the inputs state. Each bit contains
the current state of the corresponding STEPP device input/output. If the bit x is
set to 1/0, it means that the input or output is set to HIGH/LOW state,
respectively.
