🚀 Successful UART communication demo between BeagleBone Black and TI LaunchPad CC2652R1! Initially, updating BeagleBone Black's software environment is a major asset if it is running an outdated OS image referring to 2015, with outdated libraries that could interfere with the CPU's code execution. To ensure smooth operation and compatibility with the necessary libraries' versions, I flashed the board with the Debian Buster IoT Image (2020-04-06). On the BeagleBone Black, I utilized the termios library to set up UART communication with settings of 115200 baud rate, 8 data bits, 1 stop bit, no parity bit, and no flow control by default. For the TI LaunchPad CC2652R1, I customized the UART driver using TI-RTOS7, to transmit data every second with matching UART settings. A major part of this project was implementing through a multithreading approach, with C language on both boards, taking advantage of multithreading benefits: More efficient CPU usage Enhanced system reliability Improved performance This project has been a great learning experience in embedded systems and real-time communication. I’m excited to keep pushing the boundaries in embedded technology! 💻🔧 #BeagleBoneBlack #TILaunchPad #UART #EmbeddedSystems #EmbeddedC #Multithreading

Wanna know How to control transistor Outputs using Node-Red on RPI HMI? Explore the simple example program using the RPI-HMI-OUT node. 1.Understand Button Press: Recognize that when a button is pressed, it sends true and false values, signifying a trigger event. 2. Add Switch Node to Node-RED Dashboard: Include a switch node (Q7 ON & Q7 OFF) in the Node-RED dashboard. This switch node will represent the ON and OFF states of the output. 3. Display Program on Dashboard: Integrate a button node (Toggle Switch7) onto the Node-RED dashboard. This button node allows interaction with the program from the dashboard interface. 4.Configure Program: Set up the configuration of the program according to the desired functionality. Ensure that the button press triggers the appropriate response in the program. 5. UI of RPI HMI: Check that the user interface of the RPI HMI reflects the desired functionality after configuring the program. 6. ON State: Understand that when the output is in the ON state, it signifies activation. Verify that in the ON state, the associated LED is illuminated. 7. OFF State: Understand that when the output is in the OFF state, it signifies deactivation. Confirm that in the OFF state, the associated LED is turned off. 8. Verify Hardware Connection: Ensure that the hardware connections match the schematic provided. Confirm that the RPI-HMI output is connected to the GND end of the LED, while the other end of the LED is connected to a resistor, and then to the power in (24+).

Am sure most of us have been using some form of a card or a tag to either enter the work office building or at the checkout counter in a store for payments. Ever wondered what is really going on here and how does this really work ??? Want to actually setup a physical card reader to get a sense of how it works ??? This is where the 𝐑𝐅𝐈𝐃/𝐍𝐅𝐂 technology comes into play. In my article will show how one could setup an 𝐑𝐅𝐈𝐃/𝐍𝐅𝐂 reader using a Raspberry Pi 4 along with a Mifare RC522 𝐑𝐅𝐈𝐃 module. Here is the link to my article: https://bit.ly/47kD3Po ... #iot #nfc #rfid #python
