#2339 Netduino Interfacing with Eye-Fi SD Card

Posted by EdO on 16 September 2010 - 04:19 AM in General Discussion

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.



#1194 Sparkfun LCD

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:


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.

Hope this helps
Ed

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

Thanks very much for the information, it worked !



#954 HD44780 LCD display in 4-bit mode using 4 data wires

Posted by EdO on 21 August 2010 - 06:35 AM in General Discussion

I am looking for a library that supports a HD44780 LCD display in 4-bit mode using 4 data wires. I have found a great example called Bansky.SPOT.LCD.LCD4Bit (http://bansky.net/bl...-port-extender/), but it appears to have been expanded past its original function and does not have an ITransferProvider provider that supports 4 bit mode using 4 data wires. Unfortunately Pavel Bansky appears to have gone off-line so I cannot ask him for an earlier version. Any help would be appreciated.
