console?

I have MPLAB IDE and this CCS as a plugin. So I hit "build all" and it does its thing, so I really only see a CCS window for half a second and that's it.

Is there a simple way of getting a console window so I can test my script logic on screen?

Right now I have to build the files, program the device, take the device to the field and test to see if it works. Since there's no textual output in any of this, I then have to guess why it didn't work and try again. That's been fine up until now, but I have an algorithm that works perfectly in my excel simulation and not at all in the field. I want to see the mathematical calculations as they happen to see what might be going wrong.

I know I can get a generic c+ compiler but because every compiler is different I'd rather do it in ccs.

This program was installed on this computer before I got here and I can't seem to find a console so I wonder if its a plug-in only?

Thanks.

See this post for instructions on how to use the "UART1" feature of the
MPLAB simulator to display serial output in the MPLAB Output Window:

Thanks.

I couldn't get it to work. It compiled fine and "run" worked... but no output as described in that thread.

Maybe because I'm using pic18 and the tutorial is based on a pic16? I don't know.

I can't imagine why MPLAB doesn't have a basic console type output.

This is proving extraordinarily confusing for something that should be simple.

nevermind (for now Very Happy

)

Using an example file in the help got me on the right track.

#use rs232(uart1, baud=9600)

instead of

#use rs232(baud=9600, xmit=PIN_B2, rcv=PIN_B1, ERRORS)

from the tutorial.

The "Uart1" feature of the MPLAB simulator requires that the hardware
UART in the PIC be used for output. It won't work with a software UART.
The pins for the hardware UART vary, depending upon which PIC you are
using. If you specify "UART1" in the #use rs232 statement, CCS
generates code for the hardware UART. (Or, for the first hardware UART
in a PIC that has two of them).

"Uart1" as a term used by MPLAB is just coincidentally the same term
as used by CCS in their #use rs232() statement. The MPLAB term
refers to a feature of its simulator. The CCS term is a shortcut for
the hardware UART pins, so you don't have to look-up the correct pin
numbers. The compiler does it for you.
