How to Resolve Connection Errors When Uploading Code to ATmega32A Microcontroller?

Good morning everyone! Now, every time I try to upload the code to my microcontroller, it gives me an error that it can't establish a connection with the target chip. I've checked the connection more than twenty times, and I'm sure it's correct. I've also simulated the code, and it works fine on Proteus. Even though it's a simple code just to toggle an LED, I keep getting this error. Could the issue be with the microcontroller? I have three microcontrollers, and I've tried them all, but they all...

anybody around here involved with reed-switch manufacturing/testing/selection?

anybody around here involved with reed-switch manufacturing/testing/selection? Niche subject... I'm creating a tester for reed switch parameters since about a year as my side job, and it's been fascinating to see that reed switches are everywhere yet I've never met anybody working with them/distributing them besides the friends I am working with.

Load Cell Calibration Challenges: Troubleshooting Parameters?

Hello, i'm trying to calibrate my load cell to get the right weight.. using rassbpery pi pico &i try it with arduino uno i've followed readme file of the library HX711 wich says start with no weight..than devide the raw value by the known weight to get scale factor But the result printed is always different(-/+)..even if i don't touch nothing, the weight the scale nothing... so how can i get the right paramater to pass to "set_scale()"?...

Ask a Developer: Getting Started with Reference Designs

Reference designs. They can literally get the job done for you. After all, why reinvent a wheel someone else has already developed and validated? @.PetrDvorak is a big advocate of following reference designs as closely as you possibly can, even in commercial products. Why trade a sure thing for the unknown when dealing with components as complex as a modern Ethernet controller, for example? But Petr knows where to find reference designs that align closely with his projects. Do you? In this Ask a Developer demo video, @Petr Dvořák explains why and where you can find reference designs to match any system build, and the steps you should take in there isn't one available to meet your needs....

Is there a way to fix this my ESP32CAM?

Hii guys . On an ESP32CAM, I desoldered the resistor to put the external antenna there. And there the drama 😔 Is there a way to fix this? Even if it means going back without an external antenna? Thank you....

how can I transfer audio data from ISR to a task using queues on my STM32F401 with FreeRTOS?

So guys please how can I efficiently transfer 433-byte audio data from an ISR to a task using queues on my STM32F401 with FreeRTOS? Because the ISR frequency is causing data loss, resulting in noisy audio recordings. Any alternatives to ensure a smooth data transfer? @Middleware & OS @MCU, MPU & Firmware...

Has anyone experience with the integrated pcie block from the xilinx 7 series fpga's?

Has anyone experience with the integrated pcie block from the xilinx 7 series fpga's? I cannot get is to identify as an memory controller. Of course, I selected it in the configuration dialog, but my cpu always reports it as an simple communication controller.
