Spin2 OBJ declaration in FlexGUI

JonTitus · 2020-04-17 01:45

Brand new to the Propeller 2 and its SPIN2 programming but I have programmed the Propeller 1 with SPIN. I have loaded the FlexGUI and I see in a spin2 example the notation:

obj
ser: "spin/SmartSerial"

What does the

spin/

portion of the declaration indicate? Thanks.

That reference happens to be to a spin sub-directory in the default library directory. Note that Spin2 -- as defined by Parallax -- is not yet fully supported by FlexGUI/FastSpin. It will be, though.

There is however plenty of documentation included with FlexGUI. Do take a look, and even try some things in BASIC and C as well as spin.

Thanks for your help. It might help newcomers if examples included comments that explain operations, objects, and so on. Here's how I revised the Charlieplex-driver demo. Feel free to use it (or not) as you wish. --Jon

'
' Charlieplex-driver demo.
' Connect LED MATRIX accessory board to 12-pin male header marked with P32 through P39.
' Uses objects:
'	charlieplex_test.spin2 from   C:..  flexgui414b\flexgui\samples\LED_Matrix 
'	SmartSerial from              C:..  flexgui414b\flexgui\include\spin

  _clkfreq = 180_000_000

  charlie : "charlieplex_text.spin2"  		'LED control
  ser     : "spin/SmartSerial"	      		'Serial I/O in .../include/spin/ folder

pub main | i					' Use i as a local variable

    ser.start(63, 62, 0, 230_400)		'Serial pins, setting, bit rate
    ser.str(string("Charlieplex demo", 13, 10))	'Send text to Propeller terminal
 
    i := charlie.start				'Start LED Charlie-multiplex, get next-cog value
    ser.str(string("Started cog "))		'Send text to terminal
    ser.dec(i-1)				'Send cog number to terminal
    ser.str(string(13, 10, "saying hello..."))	'Send text to terminal
    charlie.str(string("Hello, world! and:"))	'Send message to LED-display object
    ser.str(string(" saying goodbye..."))	'Send text to terminal
    charlie.str(string("Goodbye?"))		'Send message to LED-display object
    repeat					'Repeat this instruction forever

' Program Charlieplex-driver demo ends.

Yes, more comments would definitely help, and thank you for doing that for this sample.
I'll update the version in the next distribution.
