Tried many things and could not find the real cause of this.
But for just to bypass this error implemented FvM's method, although not liked the way but seems to be working for now:
Since it is a mains signal the period is known, taking a safety margin of 48-52Hz timing, just disable the INT...
I dont have spectrum analyzer, but with oscilloscope as far as I can setup, there is no disturbance at the Input of the ZC , pin B0 ! But the output of it ( just put a pin toggle inside the interrupt routine ) is get disturbed. And this disturbance is only some shifting: before starting the...
Yes the main problem should be isolating ( at least to some point ) the return path of mains. Since also the PIC supply is working on mains, any disturbed signal is coming all the way to PIC also ! There are some designs limiting the current at NEUTRAL and directly connecting LIVE, especially on...
Not sure exactly you referring to, but:
By ground actually referring to RETURN - NEUTRAL on mains, or (-) on power supply.
The motor is connected to the mains Neutral, also the power supply ! (which labelled AGRN in schematics )
The problem is that the triac is not triggered unexpectedly but...
Hi,
Designing a power control board, controlling various loads. Trying to make it universal as possible, targeted 16A max load only for switching and 5A for dimming with a triac.
Using XC8 v1.38, cpu as 18F25k22, using internal crystal and PLL with 64Mhz clock.
Also this board will make some...
You can be right, subject is deep I tried to be brief.
Big picture is to measure the volume of the liquid while flowing, without any interfering parts inside but the liquid has variety size bubbles inside and since this solution will be used on many stations cost is very important, cant use...
I am stuck at and seeking different ways of thinking or knowledge sources, any help appreciated.
I am trying to design a liquid flow meter circuit using lines of IR led – Photodiode couples, driving and reading the output with uP. At first I am trying to get a stable reading of the height of...
