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…
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…
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…
In this article, we are going to learn INA219 interfacing with STM32 microcontroller. For STM32, CubeMX IDE will be used. Using a suitable Shunt resistor we can configure the sensor for the different current ranges. Here in this article, we will learn in detail. So let’s started. INA219: The INA219 Read more…
In this article, let’s make a USB device using an STM32 microcontroller. USB is a very popular communication method and we almost every day, use such device that works with USB. Now, let’s make our own device. USB communication: USB is the most popular and daily life communication protocol among Read more…
In this article, we are going to see how we can store String in the EEPROM of a microcontroller and recall those strings to print on display or use it for different purposes. Usually, we use ROM as the main memory and RAM for variables. But this technique will save Read more…
In this article, we are going to learn about Interfacing External EEPROM with a PIC microcontroller. All the microcontrollers do not have EEPROM but sometimes, we need to save some information in EEPROM while the MCU does not have any. In that case, external EEPROM is the only solution. So Read more…
