Learn the three common STM32 interfaces: use UART for debugging, I2C for sensors, and SPI for displays or memory with STM32CubeIDE and HAL.

Combine timer, ADC, DMA, PWM, I2C, and UART into a small STM32 bench monitor with a clear firmware architecture, fault handling, and room to grow into a real project.

Learn to configure GPIO, capture a button event with an EXTI interrupt, and create a periodic time base with a timer on STM32CubeIDE using a NUCLEO-G071RB board.

Learn to read analog signals with ADC, control LED brightness with PWM, and transfer multiple samples through DMA on STM32CubeIDE using HAL.

Learn what STM32 is, distinguish chips, modules, and development boards, then choose a practical board for learning GPIO, HAL, STM32CubeIDE, and embedded firmware from the beginning.
