Flywheel and valves programming

[PicoPuls]

My question is how to approach this task in Flowcode6 and with a suitable PIC processor.
( I would prefer the ecio40p or eico40p16 )

A flywheel gives one reset-pulse at each revolution and 1024 clock pulses within one revolution.
Most PIC have a timer that could be used to follow one revolution of the flywheel, but I can't find a reset to syncronize the timer with the flywheel.

The goal is to have 6 outputs, in principle controlling valves, injection etc... where each ON and OFF of the output can be
adjusted within the range 0 .... 1023 pulses - and the last ranges stored for the next startup

It would be of great help to have some ideas about how to approach this:

Use an external CMOS 4040 counter ???
How to reset the PIC counter
Create a software counter in the PIC ??

Thanks and best regards

What is the rotational speed of the flywheel and is it relatively constant, or what is its range?

[PicoPuls]

It is very slow, up to 5 revolutions per second.
But it would be nice with an approach that allows for more speed sometime in the future

So you would be getting pulses at about 5KHz.
At that rate you could poll both the pulse and reset input signals in software, certainly with the eico40p16,
Use the pulse transitions to increment a counter, which you then compare with the various trigger points for your outputs,
clear the counter if you get a reset input transition.
You could enhance that by using an interrupt input for the pulse signal

Hi
Now when setting up ECIO40P16 I have 3 questions

The processor on ECIO40P16 requires 3.3 V Is it a potential conflict to use EB061 Application Board and different other 5V Eblock modules ?

"ECIO can easily be integrated with LabView and Visual Basic." ( I cant find the necessary download of DLLs and suite of sample programs )

"If bootloader is overwritten it has to be sent to Matrix for restore" ( in mLOADER.zip it seems to be Bootloader.bin - can you explain )

Thanks and Best regards

ECIO40P16 can be used with EB061, but you just need to be careful what you attach to it.
The 3v3 dsPIC33EP256MU806 device on ECIO40P16 has a few 5 volt tolerant pins, mainly on Port D.
We have a number of products that have (different) internal bootloader firmware, for ECIO40P16 it has to be sent to Matrix for restore in the unlikely event of it getting corrupted.
I think the references to LabView and Visual Basic are related to the fact that the device can be used as the basis of a USB peripheral.

Hello,

This link has some Labview and VB examples used with the Flowcode USB Slave component.
