It is not too difficult to start ESP32 provided you go through the right steps. It is ready for beginners and everyone interested to learn STM32 ARM-Cortex-M based microcontrollers together with its ecosystem around microcontroller itself. It got me wondering what the differences between the hardware are. ESP32 can interface with other systems to provide Wi-Fi and Bluetooth functionality through its SPI / SDIO or I2C / UART interfaces. rising tide IoT: OSes & ... Technically, those work on ESP32 too. ESP32 and ESP8266 boards are similar, and you wonât feel almost any difference programming them using MicroPython. TinyML benchmark: Arduino Portenta H7 vs Teensy 4.0 vs STM32 Nucleo H743ZI2; Esp32-cam motion detection WITH PHOTO CAPTURE! This means that anything you write for the ESP8266 should also run with no changes or minimal changes on the ESP32 (mainly changing the pin assignment). STMicroelectronics recently launched STM32 step-by-step learning program to educate and speed-up learning curve. ELI5 (or just a noob) why I would want to use the STM32 over the ESP32 for DSP programming.
