Re: Documentation broken link

the new WAITMICRO word is not referenced on the TIMER page (like in an earlier version of the Help) -- online version a person would have to know to "Search" for the word, I only see it in the index. on the "Contents tab" NOT the "Index tab" ?? is there a reason the "alphabetical KEYWORDs' don't lis...

Re: Multi core BASIC being tested

Yes, multi-core means several mcu.s - but unless you load each one separately with a program, there is the sense of multi thread -- the main M4 passes off a routine or command [ie thread]to the M0 or the IO processor. the programmer has to keep the result and it storage location in mind to use in th...

Re: Exception Processing

Whooho - you're in like Flynn
use 'em up - that is what they're there for.

I've ordered some level translators 74LVC54? devices for my projects.
*ANY luck on the Exceptions?? what led you to believe it was that, and not a program variable going wonkers
(along the lines of zero reading from the ADs)

Re: Exception Processing

if you need that much current - try a ULN2003 ?? or possibly a 7407-type
transistors are another option but
IN ANY CASE from what I understand - you will need a current limiting resistor
be it the base of the transistor or the TTL type of chip.

Re: Multi core BASIC being tested

so multi-core implies multi-tasking, with the associated symaphores/mutexs; round robin or co-operative scheduling -- ** how is this progressing ?? - we are getting to the point of a OS almost- Well Pi and Beaglebone Black are there with LInux -- Is FreeRTOS in the wings?? ** enlighten us , oh wise ...

Re: Exception Processing

personally - I think you are pushing to the max --- limits
p0(29 & 30) AFAIK are not 5v tolerant so I would increase my R
can you get by with about 10-12 ma for your LEDs --
**I assume you are just debugging your circuit/PROGRAM - not final assy.

Re: Exception Processing

Good question -- info from the data sheet isn't 100% clear it states up front -- All GPIOs support a new, configurable open-drain operating mode. Single 3.3 V power supply (2.4 V to 3.6 V). Imax for supply or ground current is 100ma - total, I think the chip uses 50ma.... ** on page 47 it shows a ch...

Re: Exception Processing

Hi, Good morning - I was looking over your previous posts -- Good info -- 'cuz I want to add some Arduino shields to a ProStart Board - (I haven't graduated to the SuperPro YET). I'll have to look at the 5v turn on issue a little more. I'm currently evaluating the LPC812 (it was free!) and want to p...

Re: Exception Processing

Haven't done a SuperPro yet, and not much C - but memory issues came to mind. this could also imply stack usage/overflow. not sure how much memory clean up MakeItC does. --- are there any faults printed out ??, or the header/version info like on a restart??? - you mention "exceptions" - have you set...
