ESP32 reboots #3

Open k7ilo opened 1 year ago

k7ilo commented 1 year ago

Is there an issue with this library working on the ESP32? When test signal is applied, the esp32 does not boot. Or if it does boot, it continues to reboot. I have tried this with multiple pins. Is there something in the code I should look for. I would rather use this library instead of the built in PCNT since i have had good results on my teensy with this.

Thanks

I have never had that issue tbh, so I can't really help.

are you using a 5v signal instead of 3.3v?

If so, you can level shift the 5v input signal to a 3.3v with a couple resistors.
