Inbuilt Led location for reference:
The Above circuits Diagrams
- At the core of the circuit lies the ARM Cortex-M4 Microcontroller (STM32F407xx). It follows specified orders to run the LED.
- A Type A to Type B Cable is used here. It links the microcontroller to the PC- acting as a bridge for programming and identifying errors. This cable facilitates both data movement and power supply to the microcontroller. One end of the cable plugs into the PC and the other into the microcontroller.
- The built-in LED of the microcontroller is the end product for this project. This LED illuminates when the corresponding GPIO pin is activated to high.
Connection Steps
- Connect PC to the microcontroller using a Type A to Type B USB cable. This connection enables the Keil software to communicate with the microcontroller for various functionality.
- See the inbuilt LED on STM Microcontroller which will glow/blink with the delay according to the program written by the user.
- Program and configure the STM32F407xx microcontroller with the help of Keil Software.
- Flash the code to the microcontroller after compiling the code successfully and doing necessary configuration settings.
- The inbuilt LED on the microcontroller should start blinking according to the program flashed into it. This shows that the setup is good and working correctly.
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.
