Using delay with WebServer handleClient

Hello, I am using this library to run a simple webserver, with the ESP32 as AP https://github.com/espressif/arduino-esp32/blob/master/libraries/WebServer/examples/PathArgServer/PathArgServer.ino Everything works fine, if there's only server.handleClient(); in the loop and nothing else. But the probl...

Do You have grounds connected between each device?
I do.

I managed to solve the problem.
It turned out, that the built in wire library for the esp32 arduino is very flaky (at least the i2c part), so I used a 3rd party library instead and now it is working as expected.

I2C between esp32 and Attiny85

Hello, I am attempting to communicate between Esp32 (devkit1 version) and ATTINY85 (digistump version) over I2C. The attiny is a slave and the esp32 is the master, but for some reason, I cannot get it to work at all. I tried the to run the master code on arduino UNO, where it works flawlessly and co...

How to use the built in 1V1 reference?

Hello, I would like to take a voltage reading with one of the ADC pins via analogRead. By default ESP32 uses whatever its current + rail voltage is as a reference,if I am not mistaken. However, I need to use the built in 1V1 reference instead. On arduino, this is very easy, I simply do this: analogR...
