Piezo & ARM Firmware Integration
My current prototype relies on a microcontroller-based platform built around an ARM family device. I already have the basic hardware in place, but I need an engineer who can close the loop between the piezoelectric drive circuitry and the embedded code…
ESP32 4G Chunked Upload Integration
I need to move a single 3 MB binary file from an ESP32 to the internet through a SIM-based 4G module, landing it on my Nginx web server with an HTTP POST request. The modem’s buffer tops out at roughly… (Budget: ?1500 – ?12500 INR, Jobs: Arduino, C P…
ESP32 Commander Life Counter Firmware
I need a clean, well-commented program for an ESP32-P4 that turns the board into a dedicated life counter for a four-player game of Magic: The Gathering – Commander format. The hardware on my bench is… (Budget: $250 – $750 USD, Jobs: Arduino, C Progr…
Arduino Sensor Parsing & GPS Sync
I need a clean, well-commented Arduino sketch that continuously reads the serial stream coming from my magnetometer sensor, extracts the meaningful fields, time-stamps each record using a GPS fix, and then forwards the newly formatted string to the boa…
ARM DSP System Porting / Enhancement
I have a mature real-time codebase that currently runs on a SoC including ARM and a CFX DSP. The next product revision will ship on a different ARM architecture, so the task is to take everything that works today and make it work just as well—if not be…
Headband EEG Wearable Development Lead
I’m bringing a next-generation wireless headband to market that gives team-sport athletes real-time neurotraining feedback from clean EEG signals. To move from concept into a field-ready prototype I need an embedded and firmware specialist who can own …
A18R Camera Docs & Sample
I own an A18R 3-D face and palm-vein recognition camera but was given no material to work with. To start development I need three things: the official user manual, the full technical datasheet, and a working sample project that illustrates how to build…
ESP32 Firmware Backup Assistance
I need a reliable, step-by-step walkthrough for pulling a complete firmware image off my ESP-32 over USB so I can keep it as a safety backup. The board is powered up and reachable, but I’m still undecided on which utilities or drivers to install… (Bu…
STM32F072 SLCAN Firmware Build
I already have the source for an SLCAN-compatible firmware that targets the CANable2 / SH-C31A board (STM32F072). What I’m missing is a clean, reproducible build and a ready-to-flash binary. Scope •… (Budget: $10 – $30 USD, Jobs: Adobe Flash, C Pr…
STM32 DS18B20 Real-Time Temperature Reader
I’m integrating a DS18B20 temperature sensor into my STM32 board and need clean, lightweight C code that talks to the sensor over its native 1-Wire bus. I don’t want to rely on HAL or LL helpers—I’m after fully custom code that I can drop into an exist…
