RP6 ROBOT SYSTEM - 2. Installation of the Expansion Module
If you also have the 16x2 characters LCD, you should connect and mount it to the ex-
pansion module PRIOR to installing it on the robot.
The 14-pin ribbon cable of the display is very flexible and can be easily folded. In or-
der to fit well under the display, you
should fold it for the RP6-M256 module
like shown on the picture (may vary ac-
cording to the display model!).
Now you can fasten the display e.g. with
20mm or 25mm spacer bolts, suitable
nuts and screws on the expansion mod-
ule.
You can also use any other text LCD with
HD44780 compatible controller. You just
need to solder a suitable cable to the dis-
play.
Please pay particular attention to
the proper pin assignment! Note: The initialization carried out by the bootloader is set
for a 16x2 characters display. The status messages can appear on larger displays as
well but maybe in other places than expected.
You don't need 4 spacer bolts as shown on the picture. 2 pieces (both on the front
or
on the rear) are sufficient to fasten the display.
CAUTION: During installation of the
display, please make sure that the
thin antenna cable is not clamped
under the spacer bolt! This can hap-
pen easily, so push the cable care-
fully aside when you fasten the
spacer bolt!
Tip:
The RP6-M256 is supplied with two small PCB pieces with two M3 drill
holes. These are OPTIONAL (i.e. they are normally not necessary) and
can be used as adapters for LCDs where the mounting holes don't
match exactly to the drill holes on the PCB. You just might need to fit
the height of the spacer bolts with nuts or rings.
The PCB pieces can also be used for other mounting purposes, e.g. to
install the antenna mount at another location (with slightly inappropri-
ate drill holes). You eventually only need two additional M3 screws and
nuts.
