This repository contains professional STM32 embedded systems projects, each including Proteus circuit simulations for hardware validation. The projects demonstrate advanced peripheral configurations (USART, SPI, ADC, TIMERS) using HAL libraries with optional low-level optimization.

STM32 peripheral libraries such as ADC, UART, SPI, I2C etc.

The core objective of this project was to implement a set of libraries for STM32 based Microcontrollers that supports multitasking along with other various on-Chip resources like Timers, UART, ADC, DAC, GPIOS. This will make the usage of complex STM based Micro-Controllers as simple as Arduino. C/C++, Assembly languages and Keil IDE was used for the development.

Simple ADC libraries for STM32F4xx controllers

A collection of **bare-metal programming examples for STM32 microcontrollers**, showcasing direct register-level coding without HAL or libraries. Covers peripherals like GPIO, timers, UART, ADC, and interrupts — ideal for learning low-level embedded system development.

IIR Filter Design and Simulation in MATLAB Plus C Implementation Using the CMSIS DSP Libraries in STM32CUBEIDE for Multichannel ADCs in STM32 MCUs

A bare-metal ADC driver for the STM32G030 series, implemented using direct register access via CMSIS. Features ADC clock configuration, voltage regulator setup, calibration, channel selection, continuous conversion mode, and polling-based data acquisition without relying on STM32 HAL or LL libraries.

[Universtiy Project] ]A smart prepaid electricity controller built on STM32G0B1RE, featuring OLED display, RFID admin access, keypad input, SD card logging, and energy monitoring via ADC. Peripherals are managed using STM32 HAL libraries with interrupt-driven logic for efficient system control.
