For IoT applications, LPWAN technologies like NB-IoT and LoRaWAN are essential. Optimizing network coverage, performance, and power usage is still difficult, though. In order to obtain optimum battery life and dependable connectivity, how can we efficiently optimize LPWAN network parameters ...

How can passive components like resistors, capacitors, and inductors be used to design complex filter networks, such as Butterworth or Chebyshev filters? What are the challenges in selecting component values and achieving the desired frequency response?

Although I'm a complete novice when it comes to bare-metal PI, however, I do have experience on the Arduino. I've learned a lot from going through the demos, but I'm still not quite sure what clock speed means. According to the specs, the CPU in my PI4-B is a BCM 2711 with a 1.5 GHz speed. I did ...

Hi there I recently attempted to use my esp32 camera with the CameraWebServer code that the Arduino IDE offers in the sample menu. but I'm experiencing the following issues. I ran into a problem using port com3: An error with serial exception occurred: Put a timeout in writing. Note: PySerial is the ...

Hello Everyone,

What are the best techniques when using Arduino to implement communication protocols like SPI, UART, and I2C? How can you manage problems in multi-device or high-speed communication settings such protocol timing, data integrity, and bus congestion?

Hello Everyone, I recently bought a Raspberry Pi 5, and I’m encountering an issue with the RPi.GPIO library not working due to hardware changes. Consequently, I need to use a library compatible with the new hardware, like gpiod or GPIOZERO. I was advised to use GPIOZERO as it is more beginner-f ...

Hello Everyone,

In embedded systems using RTOS, how do task priority and scheduling algorithms impact real-time performance? Can someone provide examples of how different RTOS implementations handle task preemption and context switching in high-throughput applications?

Hello Everyone, Is it possible to run the matter controller and thread border router on the same ESP32 device could you please provide an example or some advice from esp? Is there any way I could make this work? It would be a great help if someone could provide some guidance or point me towards an ...

Hello, I'm using a ST Link V2 to program my STM8S microcontroller board, but I'm having problems with the programmer. I am attempting to flash a.hex file into an STM8 using STVP and the ST Link V2, but I am unable to connect to the device. Even after disabling read protection in STVP, the device is ...

Hello , I am using this module with an ESP8266 MCU. Initially, the module works fine for 20 to 25 minutes. However, after that period, it stops responding for the remainder of the day. I have downloaded all the necessary libraries and tried different sketches. When setting the serial monitor to the ...
