1 Designing with STM32F2x & STM32F4 Course Description Designing with STM32F2x & STM32F4 is a 3 days ST official course. The course provides all necessary theoretical and practical know-how for start developing platforms based on STM32F2x and STM32F4 families. The course begins with an introduction to STM32F microcontroller families and focuses on Cortex-M3/M4 architectures. The course continues with an in-depth study of the memory organization, reset unit, interrupts handling, low power modes, and all the SoC peripherals such as I/O ports, ADC, RTC, USART, I2C, DAC, TSC, SPI, CAN, USB, Timers, Op-Amps, embedded comparators, HDMI, DMA and CRC. The course also employs hardware and software design tools, and combines 60% theory with 40% practical work in every meeting. Course Duration 3 days
