The ESP32 is a powerful and versatile microcontroller developed by Espressif Systems. It integrates Wi-Fi and Bluetooth capabilities, making it suitable for Internet of Things (IoT) applications. The ESP32 is known for its low power consumption, dual-core architecture, and a rich set of peripherals. It can be programmed using the Arduino IDE or using the Espressif IDF (IoT Development Framework).
Connection
We will use the STM32 MCU to send the data to the computer. Some of the Nucleo and Discovery dev boards from ST supports the virtual com port. This feature enables the USB connected for the ST link to be also used for the data transmission between the MCU and the computer.
The Virtual Com Port is supported by many Nucleo and Discovery boards but not all. You need to check the schematic of the board to confirm whether the respective board supports it.
Below are the images from the schematic of the Nucleo F446RE and Discovery F412.
The STM32 microcontroller series is a family of 32-bit ARM Cortex-M based microcontrollers designed by STMicroelectronics. These microcontrollers are widely used in various embedded applications, from simple projects to complex systems. STM32 devices are known for their performance, low power consumption, and a wide range of peripherals. They are commonly programmed using the STM32CubeIDE integrated development environment (IDE).
