STM32F407xx MicroController

STMicroElectronics’ STM32F407xx family is based on the high-performance 32-bit RISC engine ARM® CortexTM-M4, operating at frequencies up to 168 MHz. The single-precision floating point unit (FPU) in the Cortex-M4 core supports all ARM single-precision data processing instructions and data inputs. It also uses the Memory Protection Unit (MPU) and all DSP commands to secure the application.

The STM32F407xx series includes two APB buses, three AHB buses and a 32-bit multi-AHB bus matrix, as well as a variety of I/O upgrades and peripherals. It also includes high-speed onboard storage (up to 1 MB flash memory, up to 192 KB SRAM), up to 4 KB spare SRAM, and more. The entire hardware includes three 12-bit ADCs, two DACs, one low-power RTC, 12 target 16-bit timers (including two PWM timers for motor control), two target 32-bit timers and a true random number generator (RNG). ). They also have sophisticated and complex communication skills.

Based on the ARMv7 instruction set, this microcontroller is popular in embedded systems due to its cost effectiveness, performance and 32-bit processing capability. The special model STM32F407xx has features suitable for many applications.

Blink LED in Arm Cortex Microcontroller using Keil software

The ARM Cortex-M4 is a 32-bit processor core that is widely used in microcontrollers for embedded systems. It is designed to be highly efficient, and low-cost. The Cortex-M4 architecture is based on the ARMv7 instruction set architecture and It’s capable of handling up to 4GB of memory address space.

In this tutorial, we will demonstrate how to blink the inbuilt LED of an ARM Cortex M4 microcontroller using the Keil software and the C programming language.
