ATOMIC_BLOCK in avr-libc
Even in microcontrollers, there are various interrupts that can be used, so the execution of the code may be interrupted. This can be managed by using atomic operations.

Investigation on USB Applications with AVR
The key point of using AVR for USB is whether the chip itself has built-in USB support. Currently, only ATmega32u4 is still in production, but it may also be difficult to obtain due to semiconductor supply shortages.
Raspberry Pi Pico PIO Exploration
In early 2021, Raspberry Pi released the pico microcontroller, which is quite affordable at just over 100 Taiwanese dollars. One interesting feature of it is PIO, which allows the implementation of different communication protocols using specialized assembly language and architecture without consuming the resources of the main processor.
Creating an Air Quality Monitoring Application with Arduino and ESP32 (4) - WiFi
Our goal this time is to bring the whole idea into place, so I purchased a ESP32 development version that already has built-in WiFi and Bluetooth to develop!
Create an Air Quality Monitoring Application with Arduino and ESP32 (3) - Arduino
This will talk about some mines on Arduino and language unfamiliar and stepped on
Creating an Air Quality Monitoring Application with Arduino and ESP32 (2) - Data Communication UART
Among the networks, the most common one is the TCP protocol. To ensure the accuracy of data transmission, we need a series of mechanisms to ensure that the data is accurate and that both parties can receive messages. You need to do similar things in the hardware.
Implementing Air Quality Monitoring Applications with Arduino and ESP32 (1) - Introduction to Sensors
Create air quality monitoring applications with arduino, esp32, sensors! Although it is air quality, it is only the carbon dioxide concentration and temperature and humidity monitoring. If there is a sensor, it is not too much of a problem.
