25 SharesArticle Technical Rating: 8 out of 10The STM32 family of microcontrollers from STMicroelectronics is based on the ARM Cortex-M 32-bit processor core.The STM32 series are some of the most popular microcontrollers used in a wide variety of products. They also have an excellent support base from multiple microcontroller development forums.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. All STM32 variants come with internal Flash memory and RAM.The range of performance available with the is quite expansive. 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.At the other performance extreme, the STM32H7 operates at up to 400 MHz, and is available in packages with as many as 240 pins.NOTE: This is a long, very detailed article so here's a of it for easy reading and future reference.The more advanced models are available with Floating Point Units (FPU) for applications with serious numerical processing requirements. These more advanced models blur the line between a microcontroller and a microprocessor.Finally, the STM32L sub-series is designed specifically for low-power portable applications running from a small battery.You may also be interested in these other STM32 articles:–––Development ToolsDevelopment tools are required to develop the code, program the microcontroller and test/debug the code. The development tools include:.

Compiler. Debugger.

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

Keil MDK ARM (uVison5 IDE) – The MDK ARM IDE is a very stable development environment which can be downloaded for free. It allows development of code up to a program size of 32 KB. For developing larger programs a licensed version needs to be purchased here:. – 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.There are also several other IDEs that are available for use with STM32 microcontrollers. However, this article focuses on developing and flashing a program using the very popular Keil MDK ARM uVision5 IDE.Apart from the software tools, an In-Circuit Serial Programmer (ICSP) is required to program and test the code on the actual microcontroller. The ICSP is required to interface the microcontroller to the PC software tools via a USB port.The support two programming protocols: JTAG (named by the electronics industry association the Joint Test Action Group) and Serial Wire Debug (SWD).There are several ICSP programmers available that support these protocols, including:.Developing the first applicationIt’s always easiest to start with a readily available basic code framework. Then, add the code that is required for the specific application and model of microcontroller.Fortunately, 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 also can be used to configure the peripherals on the multiplexed pins of the microcontroller.The STM32CubeMX tool can be downloaded from. 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 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. Install the STM32CubeMX software. Run the application and select New Project. It will then open the MCU Selector window as shown below. Double click to select the microcontroller model being used. In this case we’re using the STM32F030K6.

It then takes you to the pinout page for the selected microcontroller.The STM32F030K6 is an ARM Cortex-M0 core with 32KB of Flash memory and 4KB of RAM memory. The example code enables the UART that uses the PA9 and PA10 pins for receiving and transmitting serial data as shown below with the green pins.Configure the UART settings under the Configuration Tab and choose the UART settings as shown below. Enable the NVIC global interrupt option under the NVIC Settings tab.Next, navigate to Project–Settings in order to add the new project name and select the tool chain IDE to be used. For this example, set the project name to ‘UARTEcho’ and select the Keil-MDK5 IDE for the project development.Finally, generate the project code by clicking Project - Generate Code. Building and flashing the codeNow open the generated MDK-ARM project file UARTEchoMDK-ARMUartEcho.uprojx.This program so far just initializes the UART peripheral and stops in an infinite loop.It’s important to note that the STM32Cube generates /. USER CODE BEGIN x./ and /.

USER CODE END x./ comment blocks to implement the user specific code. The user code must be written within these comment blocks. Whenever the code is re-generated with modified configurations the STMCube tool retains the user code within these user comment blocks.Next, define a global variable to receive a byte from the UART in the main.c source file. /. USART1 interrupt Init./HALNVICSetPriority (USART1IRQn, 0, 0 );HALNVICEnableIRQ (USART1IRQn );The code generated by the STM32 Cube will have the IRQHandler implementation of all the interrupts.

When the interrupt is enabled the code will be included into the application.Usually the generated code already handles the IRQ and clears the flag which generated the interrupt. It then calls an application callback that corresponds to the event that generated the interrupt for the module.The STM32 HAL (Hardware Abstraction Layer) implements a callback for each of the event types within each module as part of the driver.

In this example the Rx Transfer Complete callback should be copied from the stm32f0xxhalUART.c file.The callback functions within the driver will be implemented with a weak. The user needs to implement a copy of the necessary callback function by removing the weak attribute in one of the application files and then writing the specific handling required within that function.

Hi John, some how I ran across you via a telegram talking about programing STM32 controllers. This group is into Bitcoin mining. Most of the miners are rendered not profitable in a very short time frame. I have 4 of these now. One could be profitable if reprogrammed to turn up the hash rates and stabilize them. It is normal for some to come into mining at twice the target rate.

I would imagine this drop happens after it reads the program in the STM32 controller that controls the hash rates on the hash cards. I can see big money bringing lots of miners back to work. Hi Mohan and John,Excellent point raised about only 16 external interrupts being available, which means that if for example you used it on PA0, then you can’t use it on PB0 as well that burnt us before, because we did not RTFM 🙂My go-to tools are Segger J-Link, Makefile for building and Segger Ozone debugger.

Attolic TrueStudio looks like a better alternative to CoIDE now that ST have acquired them.IMO the STCube libraries are pretty obfuscated, but good enough for quick proof-of-concept. There are a lot of good libraries out there and I’m creating one too with portable architecture support for AVR and STM32L0 (it’s a WIP):Regards,Pieter.
