I have an existing JSON dataset that needs to be enriched and prepared for integration with a REST API. Key Requirements: - Augment the dataset with New Data Points, Metadata, and Additional Records. - Ensure the enhanced dataset is compatible and optimized for linking to a REST API. Ideal Skills: - Proficient in working with JSON format. - Experienced in data augmentation and metadata integration. - Knowledgeable in REST API requirements and standards. Please provide examples of similar projects you've completed in your proposal.

The project is to port a I2S mechanism implemented using PIO on Raspberry PICO to Raspberry 5 that also has this PIO peripherals. The Pico github project is here There is also: - a discussion around I2S and PIO with reference to the Pico project from the link above - a valuable resource on PIO on the target RPi5 although it does not cove specifically the I2S but may help and speed up the porting with some supplement here The project should allow to handle this I2S PIO mechanism using possibly built-in ALSA buffering functionality. A simple concept like using the DMA that is also part of the Pico project to feed ALSA buffers would be enough [if DMA can work with PIO]. My preferred idea is to test the project with sound playback, e.g. simple file player to ALSA/Pulse Audio buffers tha...

Project: OpenGL ES1.1 Initialization on STM32MP157 with OpenSTLinux This is a very simple and quick project for someone with experience in OpenSTLinux and STM32MP1 Environment: • Development Board: STM32MP157F-DK2 () • OS: OpenSTLinux with Wayland () Objective: I am seeking an experienced developer to assist with the initialization and operation of OpenGL ES1.1 on the STM32MP157 platform running OpenSTLinux. The platform includes the necessary OpenGL libraries, and the goal is to successfully initialize OpenGL ES1.1 and render a simple shape (e.g., a triangle or rectangle on a non-white background). Current Status: I’ve made partial progress in initializing OpenGL ES1.1 in C, but I am encountering errors at fbCreateWindow() and fbCreateWindowSurface() calls. It appears t...

I'm seeking an expert who can significantly enhance the speed of loading images and displaying videos on a ST7789 2.4 Inch TFT Screen, powered by an STM32H743 CPU. The images are primarily RAW images stored in an SD card. I already have the code, but the speed of the image loading is slow. The best way is to use DMA (which I didn't implement in my code) for both the CPU-Screen SPI interface, and the SDIO-CPU interface Your tasks will include: - Optimizing both initial load time and image rendering speed - Writing a high-performance library for displaying videos - Ensuring the library prioritizes performance above all The ideal candidate should have: - Extensive experience with STM32 microcontrollers - Proficiency in writing libraries for embedded systems - Deep understandin...

AC servo motor (INVT) drive connected to ATmega328P or PIC16F, your choice. The Sensor attached to the microcontroller - MPU6050 (Inertial Measurement Unit) Communication with the servo drive - MAX485 converted to TTL for microcontroller Flow:- Acceleration data received from MPU6050 --> motor position received from servo drive --> Motor actuated to the output derived formula (cannot explain in detail here)
