Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi, I am building a small timer using a MicroMite, it's slowly getting there- but I have hit a brick wall with Option Explicit and Option Default Integer. The first 3 lines are

option explicit
option default integer
OPTION AUTORUN ON

The autorun works fine, but the other two give me the "Unrecognised option" error.

I also get this error:-

SetPin 1,intl,speech_over,pullup 'Stop button
Error: Invalid syntax

In desperation I even copied & pasted an example of the SetPin line from a (someone elses) working program- it still gave me the same error.

Any help would be greatly appreciated.

Sounds like an old firmware version.

What version is it?

I would agree with John - sounds like an old firmware version. I remember reading that the option explicit and the pullup on the input pins, were reasonably recent additions to the firmware, so if you have an old firmware, or especially if you are using the MK.I MicroMite based on the PIC32MX150 chip....

Thanks for the quick replies guys- you were spot-on, it is an early version I bought in June last year. I guess I am going to have to learn to drive my new pickit3 programmer & upgrade the firmware.

It's easier then you think - I was scared of the PK3 thing for a start - seemed so complicated.

Download and install MPLAB X. Part of that huge programmer package, is the IPE, which is the basic programmer application, which for the most part, is nice and easy to drive and get code into your PIC32.

Let us know if you have any problems - plenty of helpful folk here.

BTW - welcome to the forums.

EDIT: PLEASE NOTE - if you have one of the 1st generation MicroMite's based on the 150 chip(PIC32MX150F128B), then you will find that there are only bug-fix updates for this first chip, as it has now been replaced by the 2nd generation MicroMite based on the 170 chip(PIC32MX170F256B). The practical upshot of all that guff, is that if you ARE using a 150 series chip for your MicroMite, you will not be able to upgrade the firmware to the latest version that supports the new commands you want - you must be using a 170 series chip for that. I hope that makes some kind of sense.Edited by Grogster 2015-01-16

Welcome Ken,

Please be aware of which PIC chip you have.
In simple terms you will either have a MX150 or an MX170.

If you have an MX170 (less likely if you purchased your MicroMite in June last year) then you can upgrade to MMBasic v4.6 and gain the benefit of all the software features that have been developed.

However, if you have an MX150 then you can only upgrade to v4.5E. This may not have some of the features you are trying to use so please confirm with the appropriate User Manual (geoffg.net )

The above is given to you as helpful information to potentially save you some head-scratching!!

As Grogster says, let us know if you need any more guidance . . .

Again, thanks to all for the help, I would have been really struggling without it.

I have now downloaded & installed the current version of MPlab & used the IPE to update my micromite (after first bricking it- must remember- read FIRST, push buttons SECOND!).

And yes, it is an early one (150) so the project is now on hold until my Mk11 arrives.

Ken.
