In Topic: Netduino Interfacing with Eye-Fi SD Card
16 September 2010 - 04:19 AM
When I read your article on the GPS truck tracking system, I thought about how you might be able to use the Eye-Fi to easily transfer the data logs to your "server" as you arrived into the driveway. Just thoughts as I don't have one to prototype with. If you do get one, you might find that you would need to name your logs with a "jpg" extension so the Eye-Fi transfers the files.

I think that your issue might be with the "other" pins. Pins such as R/W needs to be grounded and Vo needs to be on a pot.
Check out this diagram at http://arduino.cc/en...l/lcd_schem.png, for details. Just watch out the Digital pins are mapped differently than todotani's example from GHIElectronics library.
I also noticed that some of the sample posts in this thread, included mismatched pin types:

I also noticed that some of the sample posts in this thread, included mismatched pin types:
LCD_D4 = new OutputPort(Pins.GPIO_PIN_D13, false);
LCD_D5 = new OutputPort(Pins.GPIO_PIN_A0, false); << Wrong this is an analog pin, A for "analog", should be a digital pin
LCD_D6 = new OutputPort(Pins.GPIO_PIN_A1, false); << Wrong, same issue
LCD_D7 = new OutputPort(Pins.GPIO_PIN_A2, false); < Wrong, same issue.

See my "HD44780 LCD display in 4-bit mode using 4 data wires" post under the "General" section for solution.
