Oh, but it can. I guess it might depend on the specific device but on the 18F57Q43 I happened to use it certainly could.
HenrikOlsson Today, 05:36i'm guessing the signal is impressed on to the power line in a "balanced" phantom cailho style. i don't know how to simulate that or how to extract it properly either in any simple way with proteus ....
richard Today, 04:43Thanks Richard, appreciate the effort but (always a but)....
If I'm not reading the sim setup wrong (which I might) you have a +/-3V signal sitting on a DC-bias of 32V when, in reality, it is a...
Did a detailed analysis of how MIBAM affects pause and general code execution at PIC16F1936 running at 32mhz and with 13 BAM outputs.
This is the simple code, and output is monitored with scope.
...
if you drive a voltage divider after the dc blocking capacitor? You will have a predefined dc level to consider as "0 volts" for the comparator I guess.

Yeah, never used ZCD before either, looked to be the perfect solution for this and a good excuse to play with it.
Problem with the ZCD and my signal is that the bus idles at 35VDC for "long"...
if you don't try you will never know
richard - 11th October 2025, 06:39i have zero experience with zcd module but reading the blurb it seems to bias the pin to about 0.7 ish volts. the signal is applied through a suitable R, so that when the signal goes negative the...

richard Today, 05:48zcd is NOT particularly useful for this project since it cannot drive a timer gate directly or be a capture source for any of the pic chips that my crusty old version of proteus can...
