Hi List,
I'm trying top do a project that uses the following features:
- Web Host (OK)
- Serial (OK)
- keypad 3x4 matrix (OK)
- SD card, (OK)
- Keypad Buzzer (OK)
- External Keypad / Mode LED (NO ROOM!!!!)
Already the NetduinoPlus is fully utilized (as per pin assignments below).
Are there plans to do a Netduino with capability of the Arduino Mega? This would be really powerful.
My only alternate solution at present is to use an SPI I/O Expansion
Thoughts Welcome?
GPIO0 DRXD
GPIO1 DTXD
GPIO2 KBD INPUT
GPIO3 KBD INPUT
GPIO4 SPI1_NPCS0
GPIO5 KBD INPUT
GPIO6 KBD INPUT
GPIO7 BUZZER OUTPUT
GPIO8 KBD OUTPUT
GPIO9 KBD OUTPUT
GPIO10 KBD OUTPUT
GPIO11 SPI1_MOSI
GPIO12 SPI1_MISO_RSV
GPIO13 SPI1_SPCK

you could make a single pin analog keypad... like this http://www.instructa...eypad-Backpack/ to free up some pins from the 3x4 one

You could also use some nifty circuits to increase your I/O's:
