Learn how to interface the MCP4921 12-bit Digital-to-Analog Converter (DAC) with a TI microcontroller using SPI and TI-RTOS driver libraries. Introduction In embedded systems, Digital-to-Analog Converters (DAC) play a vital role in converting digital signals into real-world analog voltages. Whether you’re building sensor simulators, waveform generators, or control systems, a reliable DAC interface is essential….
If you ever tried to communicate STM32 microcontroller over RS485 and got confused about wiring or code, this post is for you. In this tutorial, I’ll show how to implement Modbus RS485 communication in STM32 using TTL to RS485 converter module and USB to RS485 converter connected to a PC. We will see how data…
When working on MAX31855 STM32 interface projects, accuracy and reliability are critical for industrial temperature sensing applications. Whether for furnace control or process automation, the right sensor defines how stable your system will be. In this post, we’ll see how to connect the MAX31855 thermocouple-to-digital converter with an STM32 microcontroller using SPI. Basically, this project…
Introduction A complete step-by-step guide to building a reliable cellular IoT MQTT connection using STM32 and Quectel EC200U When I first started experimenting with the Quectel EC200U-CN cellular module, my goal sounded simple:I wanted my microcontroller — an STM32 Blue Pill — to talk to the internet through 4G, publish sensor data (temperature, gas, distance,…
In this project, I’m going to show how I made a simple but useful system that can control GPIO peripherals using SMS messages. You can just send a message like “MOTOR ON”, “LIGHTS OFF”, or even “PC ON” from your mobile phone, and the STM32 Bluepill board will receive the SMS through the Quectel GSM…
Managing a website’s look can be tricky — especially if you’re changing styles manually. In this guide, you’ll learn how to build a PHP MySQL theme editor that lets you update and preview CSS variables dynamically from a simple dashboard. A website’s visual identity is one of those tasks that sounds simple — “just change…
STM32 Dual UART Communication plays a vital role when you need to read data from multiple sensors like NDIR gas sensors and send processed values to another system in real time. When I start this project, I had a simple goal – to read the NDIR gas sensor output and use that data together with…
