ESP32 and AVR UART TX response rate issue
Hi, I`m having issue with UART communication between AVR and ESP32. Issue is with TX response rate. Here is what I`m sending with AVR, first 2 bytes are command, last 3 are data: //command Serial2.write(0x01); Serial2.write(0x62); //data Serial2.write(0x69); Serial2.write(0x70); Serial2.write(0x71);...

ESP32 and AVR UART communication issue
Hi, so I`m using UART communication between ESP32 and AVR chip. Having issue with TX response rate. AVR is sending 5 bytes, first two are command bytes and last 3 are data bytes: //command Serial2.write(0x01); Serial2.write(0x62); //data Serial2.write(0x69); //high byte Serial2.write(0x70); //low by...

ESP32 PWM duty cycle measurement from input
I am trying to measure the duty cycle interval (from falling to rising edge) in microseconds of an incoming PWM signal of 20 KHz. I made a test PWM signal on a GPIO pin (50% duty) and connected it to input pin. Up to 80 microseconds it is all good and stable, but if I raise the PWM frequency, below ...
