28X

[windere]

I'm am hoping to use a 28X in a project because I need a larger number of outputs than the standard Picaxe chips. How do I program it using PIC Logicator V2 (2007), I am able to select the PIC type but how do control outputs 8 onwards?

The 28X is no longer available as it has been superceded by the 28X1. However both the 28X and 28X1 only support 8 outputs by default in Logicator (outputs 0-7).

In theory you can use portc pins on the 28X1 as extra outputs, but you would need to do this by typing BASIC text in the generic 'BASIC' cell on the flowchart by using 'high portc' and 'low portc' commands. These commands are described further in part 2 of the PICAXE manual.

The current version is 3.3.0.

Technical,

I have read your responses to threads about portc on the 28X1.

But I want it made clear that I cannot RENAME the portc pins.

i.e.
"symbol OUTPUT_A = porctc pin0( or 0)"\

If I want to make portc pin 1 high, I have to use "high portc 1"

Correct?

But if you can also use "let dirsc = %00000010", then how would one address portc pin1 in an output statement?

Thanks.

You are correct, 'let pinsc =' is the command you are looking for.

Look at the 28X1 appendix at the end of PICAXE manual part 1 - it explains all these options.
