STM32F103RB Learning Journey

This repository documents my embedded systems learning journey using the STM32 NUCLEO-F103RB development board.
The focus is on understanding STM32 peripherals through practical examples using STM32CubeIDE and the HAL library.

Project Steps

✅ 00 – LED Blink

• GPIO configuration
• Basic LED control using HAL
• Status: Completed

✅ 01 – UART Control

• Serial communication using USART2
• LED control via terminal commands
• Configuration: 115200 baud, 8N1
• Status: Completed

🟡 02 – PWM Output (In Progress)

• PWM generation using TIM2 (Channel 1)
• Duty cycle control via CCR register
• Configured using HAL
• Hardware output available on PA0 (TIM2_CH1)
• Status: In Progress

Hardware & Software

• Board: NUCLEO-F103RB
• MCU: STM32F103RBT6
• IDE: STM32CubeIDE 1.19.0
• OS: Arch Linux

Notes

• Virtual COM Port: /dev/ttyACM0
• ST-LINK firmware: V2J46M33
• UART communication tested via terminal
