Ultra-highspeed real-time monitor of WebSocket on Microcontroller [STM32Nucleo]

I managed to send data from a microcontroller (STM32Nucleo) implementing WebSocket to a browser and display it on the monitor, but when I increased the update rate, the system became unstable and would stop or disconnect. At first I thought it was due to browser or WebSocket specifications, but when I found the cause and […]

Bidirectional communication via WebSocket on Microcontroller[STM32Nucleo]

In the previous article "Bidirectional communication via WebSocket on Microcontroller", I explained how to develop IoT for devices more closely by installing a web server in MCU and accessing it from a browser such as a PC or smartphone without using a dedicated application. Browsers usually communicate with devices according to the HTTP protocol, but […]

Microcontroller system with the HTTP protocol [STM32Nucleo]

If the microcontroller is equipped with a TCP server, which I explain in the section "Socket communication with TCP server", it can easily be developed into a web server configured with the HTTP protocol. The advantage of a system equipped with a web server is that it can be accessed from a browser, allowing communication […]

Operating the STM32 with ESP32 WiFi from a browser

Nucleo (STM32) is converted to wireless (WiFi) using the ESP32 wireless module and configured as a web server. We will introduce an application that remotely operates MCU by sending a string of command codes from a web browser on a client PC or smartphone. The details of setting up the ESP32 and browser and sending/receiving […]

Send from WiFi enabled STM32 with ESP32 to web browser

This section introduces an application that uses the ESP32 wireless module to put Nucleo (STM32) into wireless (WiFi) mode and send strings to a terminal on a PC or smartphone as a web server. The details of ESP32 and browser settings and sending/receiving are explained in "Remote control of WiFi enabled STM32Nucleo with ESP32 using […]
