The following section describes in detail how to create a simple UART application for the STM32F030 microcontroller that echoes whatever is typed on a terminal window.

The STM32Cube comes with an extensive set of drivers for all types of peripherals and support for an optional FreeRTOS (a free Real-Time Operating System) pre-integrated with the code. The STM32CubeMX tool can be downloaded from here. It also can be used to configure the peripherals on the multiplexed pins of the microcontroller. Then, add the code that is required for the specific application and model of microcontroller.įortunately, STMicroelectronics provides a very useful graphical tool called STM32CubeMx that helps in creating a basic application project for any STM32 microcontroller of your choice. It’s always easiest to start with a readily available basic code framework. There are several ICSP programmers available that support these protocols, including:

The ARM Cortex-M microcontrollers support two programming protocols: JTAG (named by the electronics industry association the Joint Test Action Group) and Serial Wire Debug (SWD). The ICSP is required to interface the microcontroller to the PC software tools via a USB port. However, this article focuses on developing and flashing a program using the very popular Keil MDK ARM uVision5 IDE.Īpart from the software tools, an In-Circuit Serial Programmer (ICSP) is required to program and test the code on the actual microcontroller. There are also several other IDEs that are available for use with STM32 microcontrollers.

CoIDE – A free tool chain which is based on a trimmed down version of the Eclipse IDE integrated along with an embedded ARM version of the free GCC compiler.

For developing larger programs a licensed version needs to be purchased here. It allows development of code up to a program size of 32 KB.

Keil MDK ARM (uVison5 IDE) – The MDK ARM IDE is a very stable development environment which can be downloaded for free.

The software tools are available as Integrated Development Environments (IDE) which combines all of the necessary tools into an integrated environment. There are several software development tools available for code development on STM32 microcontrollers. Programming the STM32 via the In-Circuit-Serial-Programmer (ICSP).

Development Toolsĭevelopment tools are required to develop the code, program the microcontroller and test/debug the code.

These more advanced models blur the line between a microcontroller and a microprocessor.įinally, the STM32L sub-series is designed specifically for low-power portable applications running from a small battery. The more advanced models are available with Floating Point Units (FPU) for applications with serious numerical processing requirements. Some of the most basic variants include the STM32F0 and STM32F1 sub-series that start with a clock frequency of only 24 MHz, and are available in packages with as few as 16 pins.Īt the other performance extreme, the STM32H7 operates at up to 400 MHz, and is available in packages with as many as 240 pins. The range of performance available with the STM32 is quite expansive. All STM32 variants come with internal Flash memory and RAM. STM32 microcontrollers offer a large number of serial and parallel communication peripherals which can be interfaced with all kinds of electronic components including sensors, displays, cameras, motors, etc. This family of microcontrollers from STMicroelectronics is based on the ARM Cortex-M 32-bit processor core.

They also have an excellent support base from multiple microcontroller development forums. The STM32 series are some of the most popular microcontrollers used in a wide variety of products.
