One idea could be to XOR the two signals to get one signal with twice the frequency where the pulse width will correspond to the delay.
If it would be simpler to measure the pulse width using some functionality in the ESP32.

Measure delay between two signals
Hi, I need to measure the delay between two repeating signals with a +-100us accuracy. The frequency is 60Hz, 50% duty cycle and the delay between the two signals can be between 0 - 5ms. The signal amplitude is 3.3V. Is it possible to do this using the MCPWM, RMT or any other HW function in the ESP3...

Re: ESP32 resets on mechanical shock
To test the hypothesis you could feed the ESP32 using an external signal generator through a flexible coax cable. Or try a MEMS based oscillator which should be more shock resistant than a crystal. In one design I have seen the oscillator mounted on a cushion of foam to reduce vibrations/shock. If y...

Re: ESP32 resets on mechanical shock
Could also be the crystal oscillator, vibrations will modulate the output signal.

LWIP Statistics
Hi,
We are interrested in to characterize the data consumption at byte level for our application.
Is it possible to read out the statistics defined in the "stats_mib2_netif_ctrs" struct ?

Recommendations for creating production build
Hi, Browsed through the ESP-IDF documentation but couldn't find any specific part regarding recommendations for creating a production build. Our device will be used in a public environment where anyone can access it and easily steal it if wanted, so making it as hard as possible to reverse engineer,...

Could you share the same information for ESP-WROVER-I and IB?

ESP-WROVER version for new design
Hi,
For a new design shall we choose ESP32-WROVER-I or ESP32-WROVER-IB?
Will the I version be phased out since that's the oldest?
