Thank you Steve... that's very helpful. Reading from Port B (from within the interrupt service macro) does indeed clear the mismatch condition. I suppose this raises an interesting question (which you folks will no doubt have thought about in designing Flowcode) and that is, when should a relatively...

I'm experimenting with 'RB Port Change' interrupts, using a Formula Flowcode Buggy. Some of the results are not quite what I expect! Problem 1: I have very simple program, which enables the 'RB Port Change' interrupt, with a simple interrupt service macro. My main program then simply executes a hold...

Here's the scenario: I have a byte variable, 'my_variable', which may have a particular bit set. If I have a DECISION block which contains the following statement: IF... my_variable AND 1 = 0 the simulator does the predictable thing, and performs a bitwise AND. If the appropriate bit (least signific...

Thanks, Steve - I'll mail the files to you. However, I think I have made some progress in terms of the symptoms - the errors are present whenever I try to use the PWM component in a flowcode program that also contains the Formula Flowcode component. Is there some conflict here? (I was simply trying ...

When compiling to hex I receive an error from the compiler, 'unknown identifier' using PWM component. The identifiers which it thinks are undefined (I presume) are the PWM variables (Enable, ChangePeriod, etc). Have I missed a step in using the PWM component? ie, was I supposed to copy some code int...

Thanks, Benj.

I'm sure I'm not the first to assume that the wires emerge from the chassis adjacent to the wheel (whose motor) they are connected to!

Cheers!

Hmm... the instructions are a little confusing though. The designation 'left' and 'right' would normally be taken as viewed 'looking forwards' (ie in the direction the buggy moves forwards). This would make each motor connect to the circuit board without crossing over the chassis. I made precisely t...
