PIN Numbers

[Chuck Hellebuyck]

Is it possible to setup the ports as pin numbers similar to the way Arduino does?
i.e.

#define 1 portb.1

set 1 on

You mean like a CowDuino? :=)

I don't have an Arduino, but looking at some brief code examples, they wouldn't do it that way.  It appears that an internal  sub/procedure is used to initialize the port pins, and thus shield the user from knowing what a port pin (e.g. portb.1) is.  This could be done easily for a single device, or maybe a device family.

Here ya go……CowDuino:

'Here's a led blinky program with Arduino syntax
#chip 16f690,4
'Arduino like pin numbering for leds
#define red = 4
#define green = 5
#define blue = 6
'setup Arduino parameter syntax
#define output 0    
#define input 1 
#define High 1
#define Low 0
'Arduino like pin dir setting
pinMode(red, output)
pinMode(green, output)
pinMode(blue, output)
Main:
digitalWrite(Red,High)  'Arduino like port pin set/clear
wait 1 s
digitalWrite(Red,Low)
wait 1 s
digitalWrite(Green,High)
wait 1 s
digitalWrite(Green,Low)
wait 1 s
digitalWrite(Blue,High)
wait 1 s
digitalWrite(Blue,Low)
wait 1 s
goto Main
sub pinMode(portpin, direction)
    If portpin = 4 Then
        If direction = 1 Then
            bsf TRISB,4
        Else
            bcf TRISB,4
        End if
    End if
    If portpin = 5 Then
        If direction = 1 Then
            bsf TRISB,5
        Else
            bcf TRISB,5
        End if
    End if
    If portpin = 6 Then
        If direction = 1 Then
            bsf TRISB,6
        Else
            bcf TRISB,6
        End if
    End if
end sub
sub digitalWrite(portpin,state)
    If portpin = 4 Then
        If state > Low Then
            set PortB.4 On
        Else
            set PortB.4 Off
        End if
    End if
    If portpin = 5 Then
        If state > Low Then
            set PortB.5 On
        Else
            set PortB.5 Off
        End if
    End if
    If portpin = 6 Then
        If state > Low Then
            set PortB.6 On
        Else
            set PortB.6 Off
        End if
    End if  
end sub

Here is a better, and more GCBasic like syntax.  Lets say the Arduino like pin numbers are used as D0, D1, D2…. and A0, A1, A3…

'Here's a led blinky program with CowduinoPins and GCBasic syntax
#chip 16f690,4
'Arduino like pin numbering for leds
Call CowduinoPins
'reference descriptive names <or not>
#define red D0
#define green D1
#define blue = D2
'set port direction
dir red out
dir green out
dir blue out
Main:
Set Red On
wait 1 s
Set Red Off
wait 1 s
Set Green On
wait 1 s
Set Green Off
wait 1 s
set Blue On
wait 1 s
Set Blue Off
wait 1 s
goto Main
'this sub could be made into an .h file for the GCBasic include folder
'and then assembled in the program with the compiler directive
'#include <CowduinoPins.h>
sub CowduinoPins
    #define D0 PortB.4
    #define D1 PortB.5
    #define D2 PortB.6
    #define D3 PortB.7
    #define D4 PortC.0
    #define D5 PortC.1
    #define D6 PortC.2
    'etc.......
    #define A0 PortA.0
    #define A1 PortA.1
    #define A2 PortA.2
    'etc.......
end sub
