PropBasic Counter question.

Mickster

How do I simply set the counters to accumulate POS pulses?

This page of the manual is blank.

Cheers!

Here is the application note and example code (AN001) for using the counters.

Bean

Check out page 45.

Let me know if you need more info.

Thanks guys, I already have all of the above

Do I understand this correctly?

COUNTERA mode{, apin {, bpin{, frqx{, phsx}}}}

mode = 80 (pos edge detection)
apin = 7 (the pin I want to count)
bpin =0 (not using)
frqx = 1 (the increment value ?????)
phsx = 0 (the initial setting of the counter???)

So, at any time in my code, PHSA can be referenced to determine how many pulses have occurred?

Correct.

Bean, where can the 1.43 executable be obtained? I've looked far and wide but can only conjure up 1.42. The 1.43 pdf you just posted is new to me and has a couple of things documented and/or new that are interesting. STACK, I2CSPEED and documentation of the SERIN timeout, label parms for example,based on a super quick speed read of said doc.
As always, thank you for PropBasic, it's fantastic for quick, fast prototyping of ideas for sure!

I can't find a 1.43. 1.42 is the last I downloaded on 9/15/2015.

I don't think I've posted version 1.43, but there is no additional instructions.
Only some optimizations.
I'm actually up to version 1.44, but there are still some things I want to improve.

Version 00.01.43
  Changed SERIN so it doesn't wait for stop bit
  Optimize Divide and remainder operation [June 27,2014]
----------------------------------------------------------------------------
Version 00.01.44
  Made PAUSE a subroutine
  Made *, */, **, /, and // operators subroutine
  Optimized COUNTERx if bpin is -1 no instruction is generated
  Optimized var = -shortIntConst to NEG var,#shortIntConst
----------------------------------------------------------------------------

Thanks, Bean, I'm looking forward to your optimizations.
