| This example application demonstrates
how the Sted-E-Man can be controlled remotely using a Wireless Control
Module (WCM) connected to the Sted-E-Man and a Wireless Handheld Controller
(WHC) issuing directional commands to manipulate the Sted-E-Mans course
and direction. |
| The WCM is connected to the OOPic-C
or OOPic-R microcontroller via the I2C/Programming Header. |
| On power up, the Sted-E-Man will
run through its start-up process and then wait in its start position
until commands are received from the WHC. |
| To connect to the OOPic-C you
will need to solder header pins to the 5 pin Prg connector. |
| Connections
are as follows: |
| WCM |
OOPic-C & RCBV2 |
OOPic-R |
| I2C Input |
Prg Connector |

| Servo connections on the Sted-E-Man
are as stated in the Sted-E-Man documentation. |
| In order to control the Sted-E-Man,
you need to set up the WHC to look for the correct remote node. This
will match the WCM onboard the Sted-E-Man’s local node set-up
(in this example it is 2). The WHC’s local node is always 253.
The reason for setting up these nodes is similar to putting send and
return addresses on a parcel you are sending to somebody. Without
them, the parcel will never be delivered and you will get no confirmation
of delivery. |
| When both units are set-up, you
are ready to control Sted-E-Man wirelessly. The WHC should be set
to button presses on the Red status led. This means values of 5 (forwards),
7 (Left), 8 (Right) and 9 (Stop) are sent when the corresponding arrow
buttons are pressed. |
| You can also use a second WCM
connected to a PC in place of the WHC to control the Sted-E-Man wirelessly
from your desk! |
