AT Mega Zero

Blynk 2.0

Do you have arduino ide librarie recommendations that work with the AT Mega Zero ?

what is “AT Mega Zero”?

Its a development board based on the Espressif Esp32-S2 chip.
I tried the BlynkSimpleESP32.h library but it won’t let the atmegazero compile in arduino ide.

I’ve just done a quick test.
I have Blynk library v1.2.3 and ESP32 core v2.0.11 installed and am using v1.8.19 of the IDE.
I took the Blynk Blink example for ESP32 from the Sketch Builder/Example Browser, chose “ATMegaZero ESP32-S2” as my board type and compiled the code.
It compiles fine, the starts trying to communicate with the board (which I obviously don’t have)…

It seems that your problem has something to do with your software setup on your PC.

your link says

The ATMegaZero is a microcontroller board based on the Atmel ATMega32U4 microchip

There’s a link on the left hand side that says “ATMegaZero ESP32-S2 (New)” which fits the description of…

so I assume that’s the board he’s talking about.
