Embedded Systems STM32 Low-Layer APIs(LL) Driver Development from Udemy

Welcome to the Embedded Systems STM32 Low-Layer APIs(LL) Driver Development course.

The STM32 Low-Layer APIs ( known as LL) offers a fast light-weight expert-oriented layer which is closer to the hardware than the HAL APIs (Hardware Abstraction Layer). The LL offers low-level APIs at the register level with better optimization. These require deep knowledge of the MCU and peripheral specifications which we shall cover in this course.

With a programming based approach, this course is designed to give you a solid foundation in firmware and peripheral driver development for the STM32 family of microcontrollers. The goal of this course is to teach you how to navigate the microcontroller reference manual and datasheet to extract the right information to professionally build peripheral drivers and firmware using the STM32 Low-Layer APIs

By the end of this course you will be able to develop drivers for peripherals like the ADC, UART,PWM, GPIO, TIMER,I2C, SPI, RTC, WWDG, IWDG, RCC, EXTI etc. You will also master the STM32 architecture and how to build professional embedded firmware for STM32 microcontrollers.

Please take a look at the full course curriculum.

REMEMBER : I have no doubt you will love this course. Also it comes with a FULL money back guarantee for 30 days. So put simply, you really have nothing to loose and everything to gain.
