Overview
This course provides an in-depth understanding of ARM Cortex-M4 microcontroller programming using the STM32 platform. Participants will gain hands-on experience in using STM32CubeMX and STM32CubeIDE for embedded system development. The course covers topics like GPIO programming, timers, interrupts, serial communication (UART, I2C, SPI), ADC configuration, debugging, and ARM bare-metal programming. Designed for entry-level embedded engineers, this course enables practical implementation through guided exercises using development boards and sensor kits.
