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…
Hi guys this article is to discuss the Lora module interfacing with the STM32F blue pill board. The driver is implemented to transmit and receive the data between two devices in Keil IDE using the HAL driver. This library mostly focuses on the Lora mode and uses SPI communication. In Lora mode, we can access…
Hi guys, in this article we will discuss how to monitor the DHT sensor values in the Blynk application. For this we should have an account in the Blynk app, we can signup into Blynk either by Gmail or Facebook. After signup create a project with text labels, and we get an auth key to…
Hi guys, this article is to read the DHT sensor values temperature and humidity, these values are displayed on the PyQt5 GUI application. This GUI is designed in Qt designer (see below image) and converted to the .py file. DHT11 is a temperature and humidity sensor. This sensor has 3 pins (VCC, OUT, and GND)….
Introduction: In this tutorial, I am going to explain about sending sensor values to the thing speak server. ThingSpeak is an open-source server, so users just need to sign up with your email id. After sign up creates a new channel to get an API key, this key is unique for every channel. By using…
