string array
PostPosted: Fri Dec 04, 2009 6:36 pm     Reply with quote

Compiler Version 4.099 PCM

I think what I want to do is a string array, but I can't get one declared. Here's what I want to do:

Say I define 8 active high relays:

Code:
#define Relay0 PIN_C0
#define Relay1 PIN_C1
#define Relay2 PIN_C2
#define Relay3 PIN_C3
#define Relay4 PIN_C4
#define Relay5 PIN_C5
#define Relay6 PIN_C6
#define Relay7 PIN_C7


Can I then declare a string array:

Code:
string strarray[8] = {"Relay0", "Relay1", "Relay2", "Relay3", "Relay4", "Relay5", "Relay6", "Relay7"};


And activate Relay 0 with:

Code:
OUTPUT_HIGH(strarray[0]);


Is this a legal move?

The i/o functions don't take strings as parameters. They take numbers
as parameters. Declare it as an array of integers, and initialize it to
the "Relay0" names, etc., but without the quotes on the names.

You didn't post your PIC. If you're using a 16F, then declare the array
as 'int8'. If you're using an 18F PIC, then declare it as 'int16'.

As mentioned above, will work, I have also done the same, but not predefined.

I have done this:

Code:

int16  outputs[8] = {PIN_C0, PIN_C1, PIN_C2, PIN_C3,
                             PIN_B0, PIN_B1, PIN_B2, PIN_B3};

output_high(outputs[0]);



But predefining like you did does look cleaner when needed to edit, or port.
