arm stm32f1 microcontroller Cortex-M3 tutorial

The STM32 is a family of microcontroller ICs based on the 32-bit RISC ARM Cortex-M33F, Cortex-M7F, Cortex-M4F, Cortex-M3, Cortex-M0+, and Cortex-M0 cores. STMicroelectronics licenses the ARM Processor IP from ARM Holdings. High performance with first-class peripherals and low-power, low-voltage operation is paired with a high level of integration at accessible prices with a simple architecture and easy-to-use tools. The series consists of five product lines which are pin-to-pin, peripheral and software compatible.

Why is STM32 so popular?

There are many reasons why STM32 is better . These days the ATMEGA series controller’s are widely used among hobbyist becoz of arduino boards. If we compare ATMEGA328 which sits on arduino uno with STM32 . STM 32 is much better compare to ATMEGA IC’s in terms of everything.
 

Which programming language is used in STM32?

True, it makes it much easier to get started, however it uses a simplified version of the C / C++ language. So learning it won’t let you migrate later on to another IDE, or even to another family of microcontrollers. Arduino is very limited when it comes to STM32.

These microcontrollers are used in a variety of applications, from simple printers to complex circuit boards in vehicles. As a result, the technical know how of developing firmware and embedded systems using STM32 microcontrollers are an essential skill-set for an engineer in electronics and communications

Note that you will need to sign up for an account on ST’s site (free, but requires an email address). Follow the installation process, accepting all the defaults. Start STM32CubeIDE, and you will be presented with a window asking you to choose your workspace.STM32CubeIDE is an advanced C/C++ development platform with peripheral configuration, code generation, code compilation, and debug features for STM32 microcontrollers and microprocessors. It is based on the Eclipse®/CDT™ framework and GCC toolchain for the development, and GDB for the debugging.

  1. create a new project in STM32CubeIDE.
  2. in Target Selection Tool, select the appropriate microcontroller or Evaluation Board.
  3. give your project a name.
  4. in Device Configuration Tool initialize all the necessary peripherals.
  5. generate a project.
  6. complete this project with your code.

 

How do I use interrupts in STM32?

The ARM processor has two levels of external interrupt, FIQ and IRQ, both of which are level-sensitive active LOW signals into the processor. For an interrupt to be taken, the appropriate disable bit in the CPSR must be clear
