Re: Frequency Measurement on digital input

Wouldn't you get more accuracy by using a hardware signal to gate the counter? Like... using a 5Hz signal from the LEDC, fed to a GPIO that's also used as the counter gate. Then it's just a matter of adding an interrupt routine on the negative edge of the gate signal to grab the count. I've had to ...

Size of the code generated by the compiler

Hi all, why the code generated by the compiler is around 3-4 times the size generated for the ESP8266 ? For example, the same ESP8266 source code compiled for the ESP32 generates a much bigger program size. A soon as a new library is included in the code, the program size increases very fast, reachi...
