?? Understanding the CAN Protocol: Key Elements You Should Know ???? The Controller Area Network (CAN) protocol has been a game-changer since Bosch introduced it in 1986. It simplified communication between the Electronic Control Units (ECUs) in vehicles by allowing data to flow seamlessly over a single bus. The Mercedes-Benz W140 S-Class was the first car to use CAN, opening the door to smarter, more efficient automotive networks. But what makes up a CAN frame? Let’s break it down: 1?? Start of Frame (SOF): A 1-bit signal that marks the beginning of a message and synchronizes the system. 2?? Identifier (11 bits for Classic CAN, 29 bits for Extended CAN): The identifier shows the message priority. Lower numbers = higher priority (important for safety-critical data, like braking). 3?? Control Field (6 bits): It includes the Data Length Code (DLC), which tells how many bytes of data are included in the message. 4?? Data Field (0-64 bits, 0-8 bytes): The heart of the message, carrying important data like sensor readings or commands. 5?? CRC Field (15 bits): This field checks for transmission errors, ensuring the data is accurate. 6?? CRC Delimiter (1 bit): A reserved bit that helps separate the CRC from the rest of the data. 7?? ACK Slot & Delimiter (2 bits): The ACK Slot signals that the data was received correctly, while the Delimiter keeps everything organized. 8?? End of Frame (EOF, 7 bits): Marks the end of the message, making sure everything flows without overlap. ?? Total Frame Size: CAN frames can range from 47 bits to 127 bits, depending on the message’s data and identifier length. With its efficient structure, the CAN protocol has become a critical part of modern automotive and industrial communication systems. ?? #CANProtocol #AutomotiveTechnology #VehicleCommunication #IoT #Innovation #TechExplained

?? I’m excited to share a recent project I completed with my colleague Wafa Tlili, entitled "Smart Distance Monitoring System with CAN Bus" using the STM32F407G-DISCOVERY Kit. The setup involved two nodes connected via CAN bus: one node dedicated to distance measurement with an HC-SR04 ultrasonic sensor and a 16x2 character LCD display with an I2C interface, and the other serving as the central board. ?? The distance measurement node collects data and sends it to the central board. If the detected distance exceeds 10 cm, a buzzer activates and a blue LED lights up. We also implemented a feature to deactivate the buzzer using a push button, with the distance continuously displayed on the LCD. ?? This project showcases practical applications in safety systems, industrial automation, smart home setups, and vehicle parking assistance. It illustrates how embedded systems and sensor integration can solve real-world problems and enhance efficiency. ?? Special thanks to Centre Supérieur de Formation (CSF) for providing us with the resources that made this project possible. ??

?? **Project Showcase: Exploring the Inverse Relationship between Temperature and Humidity** ????? In this video, I'm thrilled to demonstrate a hands-on experiment showcasing the dynamic relationship between temperature and humidity using the DHT11 Temperature & Humidity Sensor paired with a DS1307 Real Time Clock (RTC) module. By adjusting the environmental temperature with a hairdryer, we observe real-time changes in temperature and humidity. ??? The values are dynamically displayed on an LCD, providing instant feedback as the temperature varies. This setup not only highlights the inverse relationship between these two critical environmental variables but also demonstrates the integration of sensors, microcontrollers, and display technology in real-time data logging. ??? Tools & Technologies Used: - DHT11 Sensor: Measures ambient temperature and humidity. - DS1307 RTC Module: Keeps track of the current time and date, ensuring accurate timestamps for our data. - LCD Display: For real-time output of sensor readings and time stamps. - Hair Dryer: Used to manually alter the temperature, simulating environmental changes. ?? This experiment is part of my ongoing exploration into environmental monitoring and control systems, providing insights into how small changes can significantly impact sensor readings. ?? Watch how the humidity decreases as the temperature rises, validating the fundamental principle of their inverse correlation in atmospheric science. Stay tuned for more updates on this project and others in the realm of IoT and sensor technology! #Engineering #IoT #Sensors #EnvironmentalScience #TechInnovation #ProjectDemonstration #DHT11 #DS1307

Since this circuit pretty much gives about 5 to 15 volts DC at max say 5 mA, that means the output power is 25 mW to 75 mW which is a silly micropower to be applied for something connected to the grid, particularly because the heat and losses would be probably 100x this rated power, and given the fact that this circuit can START A FIRE, or can zap someone with the hot connection to the grid, or can damage for example a scope in case it is connected to the same grid (I did this already 40 years ago), my recommendation is SIMPLE : Just have a solar cell, you can even hack an old calculator, with a simple dc-dc converter you can POWER YOUR MICROWATTS stuff out of sunlight, and simply FORGET this circuit here, you will then have something Cool, Safe, Modern, Renewable, and if you hacked a PV cell out of an old appliance, calculator, you even REUSED, in our 21st century we have to Reuse, Reduce, Recycle and Upscale by making things that were something old, into something else useful, this is the Principle of Circular Economy.
