Serial Peripheral Interface (SPI) is a synchronous serial communication interface, used to communicate between microcontrollers and peripheral devices such as sensors, displays, and memory. STM32 microcontrollers support SPI communication, which enables fast and reliable data transfer between devices. In this article, we will explore SPI communication with STM32 microcontrollers, including Read more
Learn how to implement a Real-Time Operating System (RTOS) with STM32 microcontrollers using STM32CubeIDE. This article includes an example code for blinking LEDs using FreeRTOS on an STM32 board, making it a great starting point for beginners to learn RTOS with STM32. Introduction to RTOS on STM32 Microcontrollers: Real-time operating Read more
CH340 is a very common USB-to-serial interface IC for different purposes. With Arduino, ESP, or even adding a USB-serial port with any microcontroller this IC is a kind of legend now. So, let’s check it out! What is CH340: CH340 is a USB bus conversion chip, it can realize USB to Read more
Sine wave generation using dsPIC is one of the most popular topics in electronics. Many engineers and hobbyists try this project. So in this article, I’ll start writing on sine wave generating using dsPIC. About dsPIC: The dsPIC (digital signal controller) is a microcontroller family developed by Microchip Technology. They Read more
Sometimes, we need to measure or check the internal temperature of the microcontrollers for safety reasons. So, in this article, I’ll cover how to measure the Internal Temperature of STM32 microcontrollers using the STM32CubeIDE compiler. So let’s begin. Why need to measure Internal Temperature? The answer is simple, for safety. Read more
R503 is a popular capacitive fingerprint sensor. We can use this sensor for industrial purposes. In this article, we’ll make a fingerprint attendance system with R503 capacitive sensor with Arduino. I hope this project will help many people make their own attendance system. So, let’s start! About R503 Capacitive fingerprint Read more
In this article, we are learning about PWM Generation with STM32. Here we are using STM32F103C8Tx MCU, but you can also follow the same way for most of the other MCUs. So let’s start! What is a PWM signal: PWM or Pulse Width Modulation is a kind of digital signal Read more
DMA is an important feature of any microcontroller. In this article, we are going to learn how we can use DMA for ADC reading with STM32. Here I’ll continue from the previous article. So let’s start. About the previous article: In our previous article, we discussed how we can use Read more
In this article, we will learn ADC Reading with STM32 BluePill or other STM32 ICs. We are using CubeMx IDE and here is how we can configure the code for this purpose. Why do you need ADC? ADC is one of the fundamental features of microcontrollers. ADC helps read analog Read more
Those who worked with Arduino and built any GPRS or IoT project, are familiar with Adafruit_FONA Library. This library is handy for the Arduino platform to build any GSM, GPRS, or related project. But unfortunately, this library doesn’t work with ESP32 directly. And I had awful experiences with this issue. Read more
