== RRD GLCD Adpater board

This adapter allows you to connect a [[http://smoothieware.org/panel|Reprapdiscound GLCD panel]] to a Smoothieboard easily.

{{://rrdglcdadapter:glcdav2.jpg?400}}

All of the panel's functionalities are available :

* Display
* Encoder selector
* Button
* Buzzer
* SD card

== Open Hardware

The Source is on [[https://github.com/llegoff/GlcdAdapter2|GitHub]]

== Getting one

You can now get a RRDGLCD Adapter [[http://robotseed.com|here]].
for US another version comming soon [[http://shop.uberclock.com|here]]

<callout type="primary" icon="true" title=" Two versions">

Both versions look a bit different, but are functionally identical and are used the same way. The RobotSeed version is pictured here, but the instructions are identical for the Uberclock version.

== Assembly

{{://rrdglcdadapter:glcdav2_kit.jpg?400}}

place the 3-pin connectors below the pcb

{{://rrdglcdadapter:glcdav2_weld0.jpg?400}}

and solder

{{://rrdglcdadapter:glcdav2_weld1.jpg?400}}

Mount the exp1 & exp2 connectors, and solder

{{://rrdglcdadapter:glcdav2_orig.jpg?400}}

{{://rrdglcdadapter:rrdglcdvo.png?400}}

on some rrdglcd the connector are reversed

== Power supply
If smoothieboard has good 5v regulator, or a 5V power supply, the panel of the power supply can be drawn from this one by means of a diode (ex 1N5817).

{{://rrdglcdadapter:glcdav2_power1.jpg?400}}

if not, please install a voltage regulator Recom 785.0-1

{{://rrdglcdadapter:glcdav2_power2.jpg?400}}

the diode and regulator may be mounted at the same time

== Configuration
the adapter is configured for smoothieboard v1.0a and newest

for v1.0 smoothieboard, configure the PCB

{{://rrdglcdadapter:glcdav2_config1.jpg?400}}

{{://rrdglcdadapter:glcdav2_config2.jpg?400}}

cut the jumper track, and drop a welding goute on the other part of the jumper

== Use

solder the connector missing

If you do not want to use the buzzer, leaving out the panel.buzz_pin line will leave the pin floating. As there is no pull-down on the buzzer, it will keep buzzing. To avoid this, you can either solder a pull-down resistor on the adapter board or you can use this little hack:
<code>
switch.nonoise.enable                        true
switch.nonoise.output_pin                    1.31v
switch.nonoise.output_type                   digital
</code>
This will create a pseudo-switch that does nothing, but it will enable the pull-down on the pin. You have to leave out the panel.buzz_pin line.

The V1 of this adapter was not capable of accessing the panel's SD card slot.

This functionality can be made available on the v1 by cutting track on pcb

{{://rrdglcdadapter:gcldv1_03.jpg?400}}

And soldering a cable under the pcb
