Eden Sheiko

Embedded software engineer. I write firmware for STM32 and ESP32: bootloaders, real-time communication stacks, and motor control that keeps working in the field.

That's my name on the wire: four bytes over UART, eight data bits each, least significant bit first.

Selected work

Custom STM32 bootloader

Dairycs · Alpha Mark 2 milking robot

Field robots need new firmware without anyone opening the cabinet. I designed a bootloader that takes a new image over UART, manages the flash itself, and only hands control to an application that checks out.

STM32 · UART · Flash · Cortex‑M

  1. Reset lands in the bootloader.
  2. Listen briefly for an update request on UART.
  3. If one comes: erase the application sectors and write the new image in chunks.
  4. Check the application before trusting it.
  5. Hand over: interrupts off, vector table to the app, load its stack pointer, jump to its reset handler.
Simplified for public view.

Robotic platform for the field

Taumed R&D · built with an elite IDF unit

A military-grade robot has to keep talking to its operator and keep its motors in check far from any bench. I built the embedded side on an STM32L4: the radio link, the motor bus, and the interfaces between components.

STM32L4 · Cortex‑M4 · LoRa · CANopen · UART · Maxon BLDC

Simplified. Platform details stay with the unit.
