Overview In this tutorial, we will see how to use IWDG (Independent Monitor) and WWDG (Window Monitor) in STM32. Both monitors are used for a similar purpose, but the difference is in their implementation. The main difference between the two is that a standalone watcher can be reset at any time before it times out,…
In this tutorial, I want to show you how to flash the code using a mobile phone application. Nearly every embedded system needs the ability to have its firmware updated in the field to add new features or fix bugs. However, firmware field updates can be challenging as a developer must either program their bootloader…
Real-time clock A real-time clock (RTC) is an electronic device (most often in the form of an integrated circuit) that measures the passage of time. Although the term often refers to the devices in the personal computer, servers and embedded system, RTCs are present in almost any electronic device which needs to keep accurate time. Components Required: STM32F303CB/STM32 blue pill boards –…
A/D Converters (ADC) In this tutorial, I will show you how to use ADC in STM32F303CBT6/STM32F103C8T6 to measure the Input Analog Voltages. Analog to Digital Converters (ADC) translate analog electrical signals for data processing purposes. With products matching performance, power, cost, and size needs, Analog Devices offers the industry’s largest A/D converter portfolio. As the…
The post explains about how to use stm32 pins as input using stmcubeIDE. A simple led on/off tutorial with push button as input is made to explain the coding and working. When a push button is pressed the led turns on and when push button is released the led turns off. The project is pretty…
HAL. USART. Data transfer In this tutorial, we’ll be discussing the USART / UART hardware in STM32 microcontrollers. Starting with an introduction to UART serial communication. And we’ll get a closer look at the STM32 USART hardware module and its internal functionalities, modes of operation, options, and configurations. In conclusion, we’ll take a look at the possible…
After working a lot with 8-bit microcontrollers and learning all the protocols and functions they offer, now I thought to switch to 32-bit microcontrollers. I decided to go with arm 32-bit processors, because of their popularity in the market. I choose the arm cortex-m3 processor series for my new hobby/learning projects. The reason behind choosing…
Hi everyone, this blog is to send a data to ThingSpeak server using the STM32 microcontroller. What are AT commands? AT commands are commands which are used to control the modems where AT stands for Attention. These commands were derived from Hayes commands which were used by the Hayes smart modems. Every wireless, as well as the…
Program STM32F4 with UART STM32F3 devices have a great feature. They can be programmed with the only USB to UART converter. Each device has a bootloader inside, which supports UART programming. This is not a very great method for Discovery boards, because they have a better and faster solution onboard, ST-link. But if you are…
Introduction: Hi, in this article we will see how to send SMS with SIM800 GSM module using blue pill microcontroller in Keil IDE. SIM800 is a quad-band module 850/900/1800/1900MHz and this module support USART Communication. Requirements: Blue pill – 1 ST-Link Debugger – 1 FTDI – 1 Breadboard – 1 Jumper wires Schematic Diagram: GSM…
