I will do programming in emb c, bare metal or micro python
Electronics Engineer, PCB Designer, Hardware Developer
I'm Satya, an electronics engineer. I design circuits, PCBs and firmware for products meant for manufacturing,
Most of my work is battery powered like BMS boards (TI BQ76952, BQ77915), EV chargers, L...
About this Gig
I write embedded C firmware for microcontrollers, mostly for products that have to keep working in the field, not just on a dev board.
Platforms I work with:
- STM8 (bare-metal, register level)
- AVR (bare-metal C or Arduino)
- ESP32 / ESP32-S3 (Arduino)
- Padauk low-cost 8-bit MCUs
Recent firmware work:
- Charger supervisor on an STM8S003: CC-CV control, soft start, over-voltage, over-current and short-circuit cut-off, AC-loss handling, watchdog recovery and fault codes on an LED. When one timer on that chip wouldn't count, I rebuilt all the timing on another timer.
- SPI driver for a TI BQ76952 with CRC checking, plus bring-up firmware for a 16S BMS on ESP32-S3.
What you get:
- Source code with Doxygen-style comments
- A short note on how to build, flash and test it
- Help bringing it up on your hardware
If your board already exists, send me the schematic and tell me what it should do. If it doesn't, I can design the board as well.
Please message me before ordering so we can agree on the scope.
