We have already described Idle mode and the relative power consumption, in this article we continue to measure power consumption of other sleep modes to have a brief comparison.
In a remote device, one important feature can be the power consumption, and like other devices, STM32 allows a set of Low Power states.
In this article, we look at the library to use and performance with our devices.
In this guide, we aim to explore the many aspects of interfacing the I2C protocol with the popular ESP8266 microcontroller. As a versatile and powerful component, the ESP8266 has found its place in numerous IoT projects, primarily due to its WiFi capabilities and low cost.
One of the most important features of the ESP32 is the ability to perform over-the-air (OTA) updates, which allows developers to remotely update the firmware of the device without the need for physical access.
In this article, we will explore how to perform an OTA update on an ESP32 using the Arduino IDE. We will cover the entire process, including updating the filesystem and firmware, as well as securing the OTA update with a password.
I love the I2C protocol, and when I need a sensor, every time I try to find one with this protocol, I have also written some libraries for various sensors that use I2C.
In this article, we will learn I2C basics, analyze the Arduino SAMD MKR management, add interfaces with SERCOM, and create a heterogeneous network.
It’s time to explore the new series of microcontrollers based on the rp2040 chip from the Raspberry Pi Foundation. As usual, we are going to use a generic Arduino IDE and C language.
The sensor GY-273 QMC5883L clone HMC5883L magnetometer for Arduino, esp8266, and esp32 is cheap and reasonably precise but needs some check for the clone version.
The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. This device works with i2c and SPI protocol and Is suitable with Arduino, esp8266, stm32, and esp32.
This article will explain how to program the Black Pill STM32F4 microcontroller board. It can be considered the big brother of the STM32F1 series, more powerful, and with all the features of the F1 version.
Navigating the STM32 world is more complicated than other microcontrollers, one of the reasons is that it is an extremely large world and there are many options for both software and hardware.
In this tutorial we try to create a path to follow to reach a good knowledge of these devices.
Let’s start with the famous STM32 Blue Pill, let’s see how to program it and the basic features.
