I'm looking to set up an ESP32 that communicates with a backend server over MQTT using .NET Core 9 and SignalR. The primary objective is to enable remote control of devices, with additional functionality for real-time monitoring of sensor data, such as temperature and humidity. Key Requirements: - Establish a Wi-Fi connection for the ESP32. - Implement the MQTT protocol for communication. - Set up SignalR for real-time updates. - Use .NET Core 9 for the backend. Ideal skills would include: - Proficiency in working with ESP32 and MQTT. - Experience with .NET Core and SignalR. - Knowledge of Wi-Fi connectivity and sensor data handling. - Prior work in remote device control projects. Please include relevant experience in your bid.

I need an expert in ESPHome and ESP32 boards to assist with creating YAML code for controlling a servo via ESPNow. Key Requirements: - The main purpose is to automatically control a servo from 0% to 100% then return to 0% after 1s using an ESP32. This will happen when a photoelectric retroreflector switch is triggered on a different ESP32 board. ( When switch is triggered on one ESP32 board 1. The servo on ESP32 board 2 should instantly changes to 100% position and returns to 0% after 1s) - The communication between ESP32 devices should use the ESPNow protocol. - The yaml code should be suitable for ESPHome. - The ideal freelancer will have extensive experience with ESPHome, ESP32 boards, and ESPNow. I’m an electrical engineer with no coding knowledge. This project is based on...

I have my own fully custom C++ audio DSP project that currently runs on a dedicated DSP platform (Sharc ADSP). I want to migrate/convert this project to a VSC project on Raspberry Pi5. The C++ source code is already in a „Rpi-portable” version, i.e. stripped of Sharc peripherals-specific code Hardware concept: • Use of two USB to I2S/SPDIF UAC2 converters like this: ((as input Converter1 and output Converter2) or (as output Converter2) • I2S pins of Converter 1 will be connected to RPi GPIO header and feed input audio signal via the standard RPi I2S port • Converter 2 will be connected to a Rpi USB port and will output audio signal via ALSA USB audio device Scope of work - 3 main tasks: • The current project has two „interface” buffers ...
