Timers in STM32 Timers in STM32 microcontrollers are versatile peripherals that can count input clock signals and trigger interrupts when the count reaches a predetermined value. The timer's time base unit consists of a 16-bit counter, prescaler, and auto-reload register, enabling maximum timing periods of 59.65 seconds with a 72MHz clock. Beyo ...

Interrupt Fundamentals An interrupt is a mechanism that temporarily suspends the main program execution when a specific interrupt condition is triggered. The CPU pauses the current task, executes an interrupt service routine (ISR), and then returns to continue the main program from where it left off. Interrupt Priority When multiple interrupt s ...

Introduction to SG90 Servo Motors The SG90 is a compact positional servo motor designed for applications requiring precise angular positioning and holding capabilities. Servo mechanisms, derived from the Greek word for "slave," are systems that follow external commands to achieve desired motion parameters including position, velocity, ...

Pulse Width Modulation (PWM) Overview PWM is a technique used to simulate analog signal levels by modulating the width of digital pulses. In control applications, such as motor speed regulation, the duty cycle dictates the average power delivered to the load. By rapidly swithcing the output state, the system effectively manages the average volt ...

Project Overview This project demonstrates controlling LED brightness through PWM (Pulse Width Modulation) on the MSPM0G3507 microcontroller using Keil MDK. Two push buttons adjust the brightness level up and down. Project Setup Creating the Project Obtain the MSPM0 SDK from the officiall Texas Instruments website. Navigate to the driver librar ...
