Help with Keyboard Input

mynet43

I'm running the Propeller Tool on my laptop. It's connected to the Prop with a PropPlug.

I want to be able to read the laptop keyboard when typed in to the input bar at the top of the tool.

Which library routine should I use to do this. I should know, but it's been too long since I did it.

Thank you for your help!

I always use Parallax Serial Terminal.

WBA Consulting

The standard "Parallax Serial Terminal.spin" object does that. Within the Propeller Tool you can find the Propeller Serial Terminal Demo.spin program under the "Propeller Library - Demos" folder. Also, under Help in the Propeller Tool, you should be able to open the Propeller Education Kit pdf which covers some PST usage starting on page 102.

What you are looking for specifically, is on page 106 and uses the "EnterAndDisplayValues.spin" code from the PE Kit folder.

Hi Tom,

Thank you for the feedback. I AM using the Parallax Serial Terminal.

Can you give me a simple example of how to read the input from this into a spin program?

Thank you!

WBA provides some links above, and the short answer is

ascii := pst.rx

Thanks for your help. I figured it out myself. Now I feel dumb. Too easy...

You may want to use PST's CharIn as it will wait for input (Rx may not)

  pst : "Parallax Serial Terminal"
  
VAR

  byte x

PUB Main

  PST.Start(115200)  ' baud rate on default UART pins
  PST.Str(string("Starting..."))
  PST.NewLine
  PST.NewLine

  repeat
      x := PST.CharIn       ' wait for character to be typed
      PST.Str(string("Character typed: "))
      PST.Char(x)
      PST.NewLine
