Introduction This article provides a step-by-step guide on configuring the GPDMA linked list in STM32CubeMX. It does not cover the legacy standard DMA approach, which is described in the article "How to configure the GPDMA." 1. Software prerequisite...
Introduction This article provides a step-by-step guide on how to use the Instrumentation Trace Macrocell (ITM) console to redirect print statements and LWIP debug messages in STM32CubeIDE. These tools are valuable for debugging and optimizing your ...
This series of articles will provide you with: Tips&tricks on how to implement ADC interleaved mode to double equivalent sampling rateADC interleave mode details from practical point of viewInfo on DMA data transfer using ADC Common Data Register Par...
There are two possible solutions for connecting two quad-SPI memories using only one OCTOSPI interface. Solution 1: Use a dedicated bit in the OCTOSPI_CR register for external memory selection: MSEL bit for STM32H5, STM32U5, and STM32L5 series or FS...
Introduction Some STM32 MCUs embed two unique identifiers: a unique 96-bit unique identifier and device ID. This article shows how to both obtain these values in your code, and describe some possible use cases for them. 1. 96-bit unique ID This 96-b...
After programming my STM32H7 and performing a reset, I find that I can no longer connect to my target using STLINK. Why does this happen? How can I recover my board?Note that your STM32H7’s SMPS or LDO firmware power configuration must match with the...
After updating or installing STM32CubeIDE 1.13.x or STM32CubeMX 6.9.x, you will be asked to connect to your STMicroelectronics account to download the packages. That is why you need to choose one of the following types of proxy server. Use System Pro...
The bootloader inside STM32 families uses the protocol described in AN3154. It is supported by the STM32F1, F2, F4, F7, L4 series. The purpose of this article is to give a guide on how to connect to a STM32 CAN bootloader Target, to erase and program...
Introduction Accessing SRAM during Sleep mode for debugging purposes on the STM32L476 MCU requires a specific device configuration, relative to the memory architecture of the STM32L4 and the optimization strategies for low-power consumption. To sum...
You will receive one or more compilation errors if you download any given STM32Cube package by using the GitHub Download ZIP option. This is because our repository is created using the git submodule command. So, if the GitHub Download ZIP option is...
Introduction In this article, I briefly demonstrate how to enable FreeRTOS™ within a project for STM32U5 MCUs. As a toolchain I use STM32CubeMX in version 6.11.1 and STM32U5 cube library in version 1.5.0. Additionally, we use the X-CUBE-FreeRTOS libr...
Introduction For cost reasons, many ST boards do not feature an external Crystal to feed the STM32’s system clock over the high-speed external clock (HSE). On the other hand, some peripherals need a precise clock source to work and behave correctly...
If you want a customized interface to work on your projects, you can try the alternatives offered by the STM32CubeIDE to personalize the appearance of your files. To change the default settings to give it a personal touch, follow the steps below. Cre...
Introduction The purpose of this article is to provide some external memories tips and tricks, frequently asked questions, and a list for useful link resources. 1. Overall FAQs for QUADSPI/OCTOSPI/HSPI/XSPI 1.1. How to check whether a device is sup...
When uploading a stack on an STM32WB and the wireless stack is not running, this is due to the following: Most of the time, the reason is that after the installation of a wireless stack, it by default starts running without the need for any user act...
Introduction The IWDG (Independent Watchdog) offers the possibility to exit from stop modes in STM32U5. The wakeup from stop with interrupt is supported in Stop 0, Stop 1, Stop 2, and Stop 3 modes for STM32U535/545/59x/5Ax/5Fx/5Gx as described in t...
Introduction Input capture is one of the advanced timer features available on the STM32 microcontrollers. This article guides you through the theoretical aspects of input capture, provide a practical example, and discuss troubleshooting common issu...
Introduction The STM32’s integrated RTC (Real-Time Clock) peripheral can be used to periodically wake it up from one of the various Low Power modes. It is very common for battery powered applications to have a power scheme where the application will ...
Summary This article guides readers through locating key information in STM32 documentation, using the STM32G081xB datasheet as a practical example. We illustrate how to identify details about the current sinking capabilities of pins, including the ...
After re-programming STM32H7 device, I can’t connect to the device. Connect under reset doesn’t help. Why?There are two possible root causes, that can cause this issue. First one is more probable and is related to power supply misconfiguration. And s...
