Tell us some more about what you’ve tried yet.
What experience do you have, or is this your first project ?
Did you ever use that LCD keypad shield before, or is this your first project with it ?
If i get a new toy, i’ll try some very simple examples first with it.
After you’ve got a display to work (and understand how to do that), you’ve got a nice debug tool right there.
Your question isn’t as clear as you might think it is.
The problem could be how to use the display,
It could be how to get serial data,
It could be how to handle the serial data you just got,
It could be how to convert that serial data to some format that will fit your LCD,
It could be a mismatch in speed the data comes in and has to be displayed (there will be something visible but you can’t make anything of it).
I suspect i can see some of these in the code you’ve posted before.
So it is very important for you to explain exactly where your problem is.
If you post code, post all of it.
So not just “void loop ()”.
Thanks for trying to help me. Let me share some more information about what I’m trying to do. The main story is that I want to build an arduino variometer for my RC glider. This is a very challenging project and … even thou I’m very new to the Arduino programming.
The Sener part (air module) is an Arduino Nano connected to an MS5611 pressure sensor. I have a working code mainly from the Varesano.net site. When I plug the module to the USB, it sends the Celsius, Pressure and Altitude to the Arduino IDE Serial Monitor in a string format like 31.2C;980mbar;240M (closed by a new line)
This is the data which I want to send down on a OrangeRX/TX radio link (that is also based on an Arduino) to the “ground unit” (I have to upload a newer firmware to it which has the transparent link functionality). Let’s put the radio link away for now, that is another story , a later stage on this project.
I have a serial data (ascii string) coming from the “Air unit” RX TX pins. I would like to display this data on the “Ground unit”. The Ground unit is an Arduino Uno connected to the Keypad Display shield. (Later I want change the display modes with the buttons)
Another later stage is to implement a “vario calculation routine” based on the altitude change, and connect a speaker to the Ground unit to beep the Vario. (I have already written a separate beeping routine based on a vario value parameter). So I have a few parts in drafts, now trying to compile them together.
But for now it would be perfect if I connected the “Air module” with wires to the “Ground module” and get the transmitted ASCII string displayed. (The Radio link, the beeping and some fancy features can come later :))
This is a very challenging project for me, my experience is coming from the “official” tutorials and from various articles I found on the net.
