Hello!

I bought a completely assembled Serial LCD arrangement from Micro Center as made by Sparkfun today.

 

Its their serial LCD backpack built onto an ordinary (normally parallel) LCD display. Which is a 16X2 LCD.

 

I also found the blog of one of our own's efforts to make it work with a Netduino, accordingly he made the thing work with an Arduino, and then discovered the issues inherent in making it work on something like the Netduino.

 

With me, I first got something similar to work on the Arduino, but never got this far. Has anyone else managed to replicate this work?

 

I also came across someone's work and even the Github repository. He then made it available as a Nuget package, but, ah, installing it did not work.

Let me simplify the problem:

I can properly write a program in BASIC for the BASIC Stamp that will accept data from something else and then send it onwards to a serial delivered LCD Display. That device is either the one from Sparkfun or one from Parallax who works in similar fashion to the Sparkfun one.

 

Doing so in C# or in Visual BASIC on a Netduino version 1 via its serial port at the usual pins that are part of the design are what the problem devolves into.

 

Basically I freely admit that I do not know enough about writing a program for the Netduino to do all of that. Oddly enough the same is also true for the Arduino.....

@ Dr Who.  Exactly which SerialLCD are you having difficulties with? Perhaps if we knew which one we would be better able to help you.

Huh?

Oh you want to know which one, https://www.sparkfun...ts/retired/9877 that is it. It was retired by them sometime ago. On their lists of serial LCD delivered devices, there aren't many 16X2 ones, and the white illuminated one is it.

Are you trying to use COM1? On the Netduino side...COM1 is actually the first UART (pins 0 and 1)-- the same USB port that you are using to program and debug. More advanced Arduino implementations, like the MegaADK and Netduino should use higher numbered ports. Like COM3 (pins 7 and 8) on the Netduino 3 -- which I just used to bring up an Adafruit Ultimate GPS Breakout board.

 

Once you get that all sussed, you are going to like serial comms in .NET, I think.

 

EDIT : I guess we aren't doing images anymore, but I just edited this to include the pin numbers I am referring to....
