Hopefully I would land by the end of winter... I would be at Toronto.

Hi All,

I managed to put together all the interrupts and got it working, The PIC I chose was PIC16F73. There were some glitches that I faced.

I was using PORT B for everything

Water flow sensors (cheap & reliable): https://www.seeedstudio.com/G1%262%22-Water-Flow-Sensor-p-635.html

I've used these before and they're very accurate. It creates a pulse for every rotat ...

Thanks Jay!

That was pretty awesome suggestions.

#1 is covered, I am using a lot of caps 0.1, 0.01, 0.001 - EMI is covered works perfectly with my protoboard. It has a lot of protection against ...

Thank You PCM

Thanks for the quick response PCM.

I think the waterflow sensor continuously gives a 115 Hz pulse.

With your response I think a pic can handle all these at the same time. So let me go back to my ...

Did not think of it at all, was just trying to ...

Currently you have non working code, and are blaming the compiler because this does not work. You need to start from a 'known working' location. There are extra features with the newer Modbus code, bu ...

Looks like today is my lucky day, I hooked up the hard disk from my shot OLD machine to the laptop and I was able to retrieve the PICC folder.

Here are the changes I noticed.

1) Modbus.h has som ...

An addition to my comment

I don't remember seeing any warning messages like the one below when I compiled it in the older version. I will try my best to make some time tomorrow and try to get the d ...

Thanks Mr T,

Let me pull up the hard disk that I salvaged from my burnt system. Hopefully I would be able to get more information to provide you with.

Good thing that its a weekend.

Mr T, The hardware is working fine, if I burn the old hex it works. If I burn the new hex with Compile 5.049 it will not.

I do not know how to reproduce it again since I only have the one 5.049 ve ...

Did some more testing today. Seems like Modbus is broken even the example don't work.
