Thanks for all the people who tried to help and special thanks to @chegewara for a previous help in a different topic . The problem was fixed by inverting the Signal , not by any software changes . It looks like if you hold an INPUT PIN high , you get that behaviour but if you invert the signal "whi...

@idahowalker I don't think the behaviour I'm getting from the chip is related to the method I use to detecting the edge Rising/Falling It looks like a Power Issue I powered the Opto Coupler on the Circuit above from an external source , and now I'm getting much more stable readings .. I still get th...

If this statement: // I got One ESP32 to produce a Square wave and send that through 1 wire to another ESP32 that reads the pulses , everything worked perfectly and it was so stable , but once we connect mains power .. we get those erratic readings // Then your problem is with your power circuit an...

Could be that the issue is that you're naively assuming that you're the only thing running on an ESP32... while in reality, you also have the OS, WiFi stack, BT stack, NVM, whatever that all can interrupt your task and make you detect the edge too late. Suggest you use a hardware peripheral (e.g. R...

After so many issues with esp32 as a frequency counter , I decided to put the issue here ..hopefully I'm wrong . So , during making this project ..we needed the addition of frequency counter ..and we started noticing erratic behaviour from esp32 I'm the software guy , so I thought something is not r...

Thank you so much
I'll be testing this with mains very soon
Really appreciate putting this effort for the community .

I had the same issue on Win7 . Exactly this python2.x and 3.x I also noticed that python3.4+(64bit) is not installing correctly on Win7 When I switched to Win10 , All works out of the box with no Issues . And python 3.7 (64bit) is installing fine . I think IDF is only supporting python3.7 (64bit) Ch...

You're a great help

Thank You

Yes, that's the best way to do this. Thank you so much There is no workflow at the moment for taking the same device from Development mode to Release mode If you have a use case for using the same chip in first Development then Release mode then let us know I actually don't , I just assumed that th...
