It generates the clock, acts like a serial port, acts like a disk drive, and so on. However, the ATMega32 doesn’t directly have Arduino IDE support so you have to install a toolchain for it.

If you use the Arduino IDE to program the ESP32, you might be interested in [Andreas Spiess’] latest video (see below). In it, he shows an example of using all three ESP32 UARTs from an Arduino ...

STEP 4 Set the board type and the serial port in the Arduino Programmer. STEP 5 Test the microcontroller by using one of the preloaded programs, called sketches, in the Arduino Programmer.

Serial Plotter is an amazing tool available in Arduino IDE (from v1.6.6) to visualize the “returned” data beyond just seeing numbers spit out onto the traditional serial monitor window. The Arduino ...
