Parallax Serial Terminal - help

RobertW

Hello,

I am using the Parallax Serial Terminal to display some values and would like to create some borders and/or for a simple idea, think of dividing the display into (4) quadrants, or areas. Looking at the character chart in the Propeller Tool, I see a vertical line (DEC: 145 HEX: $91), horizontal line (DEC: 144 HEX: $90), and some ‘corner pieces’(DEC: 156 HEX: $9C to DEC: 159 HEX: $9F), etc. Is there a way I can use these items to build a border on the screen? I am using the Parallax Serial Terminal object if that helps or hurts. Thank you for your help.

Thanks,
Rob

You can use those characters to build the "frame" of your display, and then make use of X and Y positioning to add content to your frame.


Take a look at the HM55B Propeller Compass DEMO in the OBEX. Specifically the Serial version on how to set a specific position...

Here is a code snip that works the same as the BS2 to set a specific cursor position in the Serial Debug window...

PUB CRSRXY(X,Y)                                         'Equal to the BS2 DEBUG command CRSRXY
      ser.tx(2)
      ser.tx(X)
      ser.tx(Y)

Hi Beau,
Thank you for your help. I understand needing to use the X-Y commands to fill in the screen. For example:

PST.Position(20,8)
PST.str(String("LED On"))

I am having trouble getting the characters themselves to display. Do I need to somehow use the decimal value, the hex value, neither, etc?

Thanks,
Rob

Hmmm.... your right.... I thought in the "Pref's" of the Terminal you could change the font to "Parallax" font. Seems like I have used these characters before in a Debug Terminal. I will have to dig a little further, maybe an older version of the Debug terminal.

Ok. Thank you. If I can not use the Parallax font, I can always go back and use the basic keyboard symbols ( |, _, -, =, etc.)
