I bought a Sparkfun Serial LCD backpack http://seismo.sparkf...om/products/258 to hook up to one of my parallel 20x4 LCDs. Soldered it up, and the backpack/lcd works fine except I can only access 16x2 of the LCD. On the sparkfun site they show 16x2 and a 20x4 firmware for this backpack. I assume I need to flash the backpack with the 20x4 firmware. Problem is, I have no idea how to do this and Sparkfun is not showing up in their own forums to answer my question, so hoping some of you good people have an idea how I would do this. Questions: 1) Have any of you hooked this backpack up to a 20x4 LCD? 2) Do you have to reflash to use the 20x4 LCD? 3) How do I go about reflashing this? Do I need a pic programmer, or is there a way to flash it from a netduino? Thanks, Scott...

I've been working on a standalone NetDuino+ solution that utilizes the following hardware.... Wind Speed / Wind Direction / Rain Fall - http://www.sparkfun.com/products/8942 Barometric Pressure - http://www.sparkfun.com/products/9694 OneWire temp sensor - http://www.sparkfun.com/products/245 Light Meter - Jameco part Serial LCD - http://www.sparkfun.com/products/9068 Door Switches - Jameco part Humidity - http://www.sparkfun.com/products/9569 I originaly built this so that I could check wind speed, and direction for flying RC Airplanes, but now I've decided to add some other things like monitoring Door Openings on my workshop, a WebServer so you can see instant weather stats and trends, etc. Is anyone remotely interested in this? If so, I'll start posting build log notes, pictures and code. I'm using a lot of stuff that others on the forums have contributed. Post a reply to this thread if you are interested in progress / code. Scott...

Bought a 2nd Netduino plus to use as a development environment so I didnt have to reboot my other one all of the time and loose all of the stats it has kept to that point. It was working great until about an hour ago. Now I get the following error when I try to deploy to the netduino+ The sequence of events was as follows: 1) I was writing a program that polled a variety of sensors (Barometric Pressure, wind speed, dir, temp) 2) I was adding support for Onewire from the Onewire ALPHA firmware to the code. I hadn't upgraded the firmware and it was getting an error during deploy. 3) I remembered that I hadn't deployed the Onewire ALPHA firmware, so I downloaded and deployed the firmware with MFDEPLOY. 4) After deploying the onewire firmware I still constantly get the following error. I have commented out all references to the onewire classes. ------ Build started: Project: Netdueather, Configuration: Debug Any CPU ------ Netdueather -> C:\Users\scott\Documents\Visual Studio 2010\Projects\Netdueather\Netdueather\bin\Debug\Netdueather.exe ------ Deploy started: Project: Netdueather, Configuration: Debug Any CPU ------ An error has occurred: please check your hardware.
