Hi Leigh and Benj,

I have a strange issue with the advanced expansion module, I keep getting an error:

C:\Program Files (x86)\Flowcode\Common\Compilers\pic16\batchfiles\pic16_C30_comp.bat reported error code 1

When I try the example file Leigh sent before it works perfectly, the minute I take out all the references to the expansion module (initialize and Digital output macro) and re-compile it, it compiles 100%, do you know why i would get this error and when I use the example code for the expansion module it works 100%?.

Running the code below on its own run perfectly with no errors

Hi,
Could you post the project that gives the error?
Re-creating the above images I do not get any errors
Thanks
Leigh

Hi Gavin,
When you use Expansion modules, the project target needs to be "MIAC (dsPIC) System"
Leigh

Oops thanks Leigh!,

Do you know why the program would reset (every 5-10 minutes) if left idle plugged in to my USB?

Does this only happen when USB connected?

Hi Leigh,

Both with USB connected and unconnected, I have run the simulations and can't find a reset?

Regards,

Gavin

What power supply are you using for the MIAC and Expansion modules?
What voltage and current capability?

its a Meanwell - NES-35-12 it a 12V 3.0A Supply, supplying both the MIAC and Miac Expansion

Hi Gavin,
OK, the PSU is good
I've not had chance to go through all your program, but I do see some instances of reentrancy,
that is, routines/macros calling themselves, this will cause problems, that can result in a reset.
For an example, RTC_SET calls HOUR_1 which calls RTC_SET

Thanks Leigh,

I just needed the program to go "back" in-case the user made an error.

One way to do that is to use connection points to the macro end

Thanks Leigh, how do you do that across different Macro's?

You cannot.
But you can use it to exit from a macro when the user cancels.

My Apologies Leigh, do you have an example?

Somehow I think the issue is with all the tag routines

Yes, I think you are correct
There is a lot of one calling another, this will cause stack problems.
Try and get the execution back to Main, have a read up on state machines.
That is, use a state variable to decide what gets called from Main.

Thanks Leigh!,

Will check it out...

Hi Leigh,

is it this below?
