 Bigger Bigger  Smaller Smaller  Reset Reset

Hi,

I am new to the Arduino community and have a couple questions on a project I am trying to work on. I just bought an Arduino Duemlinove and was curious if it is possible to attach a 3.2" lcd screen with an Arduino shield and also connect the touch capacitive shield from spark fun to the controller as well? Is this doable? Do I need a different type of controller to achieve this? Any and all comments/help is greatly appreciated!

Thanks

Check the pins needed. If both use SPI, you will have to make sure they have unique Slave/Chip Select lines.

Shields generally stack up - how will you what ends up in the middle? Perhaps breakout cabling will be needed so you can use the shields side  by side.

Try this
http://www.seeedstudio.com/depot/renbotics-side-shield-p-741.html?cPath=132_134 $9.95 or
http://www.liquidware.com/shop/show/DTX/DoubleTall+ExtenderShield
http://www.liquidware.com/shop/show/DWX/DoubleWide+ExtenderShield $19.65
I believe the renbotics has remappable pins so that may solve conflicting pin issues.
I was thinking of doing something similiar with a joystick shield and a screen, but i got a touchscreen instead.

 Maybe someone needs to develop/build/sell a "Shield Mother Board" Where there are multiple female shield connector positions layed out side by side (or vertical, or both say 2x2, 4x4) , with one position having male pin shield connectors to plug a arduino board upside down. It could be a total passive board, or just add a power connector, reset pin, and a transistor isolated LED for pin13 (because the arduino would be mounted upside down). Maybe one of the mother board edges could have screw connectors of the shield pins avalible for off board wiring interfacing.

May not be a big seller, but would give project builders another form factor to work with. Might have to include mega shield layout for maximum compatiblity? Or two versions, mega and non-mega.

I release this idea to the public domain.  smiley-cool

EDIT: just saw the "DoubleWide ExtenderShield" and "DoubleTall ExtenderShield" posted while I was typing this, same concept just more positions and a position for the arduino.

I think I have to upgrade my Eagle license before I can design something that big ...

Takes money to make money.  Plus you can write it off on taxes, or expense it as a small chapter S corp.smiley-wink

Also handy is the arduino shield list.
http://shieldlist.org/
Not only all shields are listed there but there is also A site pro shield with the pinouts they need.

WOW!! Thanks for all the replies and info. I have a lot of research to do now so I can get this project underway.
