Embedded Projects I have Developed

I keep working on different embedded projects in my spare time to learn new embedded technology, software, and applications. Some of my personal work which I did in the past is shown here. I am sharing these so others can learn and get some inspiration.

Some of my embedded system projects which I did in my spare time are mentioned below:

1. Renesas (R8C2B Tiny) General Purpose Breakout Board

Purpose of this board was to create a break outboard so that while developing various projects it will help in PoC development and test the solution quickly.


  • Character LCD
  • I2C RTC
  • Programming Connector
  • Parallel Interface for Dot-Matrix
  • UART interface for Thermal Printer
  • PS2 Keyboard Interface
  • GSM/GPRS Interface for Modem
  • Some more IOs on header connectors

2. Graphic LCD interface with Renesas MCU (R8C Tiny)

Interfaced Graphic LCD over parallel interface and build the library from scratch for characters/ string display using different fonts, and image display. It was quite a learning experience.

3. SD/MMC Card interface with Renesas MCU

For the first time, I tried Sd Card / MMC Card Interface using SPI interface. I tool one readily available adapter board and connected to the Renesas board I developed and did the coding from scratch. I was able to make it work with basis read, write function. That time I did not implement the file system and the experiment I did was with a 2GB SD card.

DC load testing at 75 Watts

5. STM32 based IoT platform (OLED, USB, RS485, WiFi, Switches, Temperature/Humidity Sensor)
