How to calculate and generate post-build CRC? 1. Cyclic Redundancy Check Cyclic Redundancy Check (CRC) is an error detection method for digital data based on binary division.CRC algorithm generates a fixed checksum code length. 2. How to calculate ...
Important Notice for Keil® MDK Users Default toolchain update Keil® MDK version 5.37 and later: Default toolchain: Arm Compiler 6 (AC6)Deprecated toolchain: Arm Compiler 5 (AC5) Compatibility alert If you’re working on STM32 projects generated using...
Introduction This article dives into how you can avoid communication disruptions. In some cases, you may see that FDCAN messages are repeated even though they’re acknowledged. You may also observe some other unexpected behavior. We cover a possible ...
Introduction It can be especially useful during code development to display messages in a terminal window about various system parameters to help with debugging. An easy way to do that is to use the printf function and redirect the output to a UART f...
Introduction UART is a communication protocol that enables the user to send data asynchronously through transmit (Tx) and receive (Rx) lines. It involves a shared baud rate between the transmitter and receiver. This article shows you how to set up an...
Summary This article provides a step-by-step guide on how to create a memory section in the linker script. Additionally, how to allocate a variable in that specific memory address region using two different IDEs: STM32CubeIDE and IAR EWARM. Introdu...
The Ethernet peripheral on STM32H7x3 is not sending, or receiving data correctly. Or, the IP stack is not able to establish connection to other devices. What could be the problem? In most cases, the problem is related to memory layout and Memory Prot...
This FAQ concerns the DSP Libraries, how to integrate them in an STM32CubeIDE project and to execute an example based on the Digital Signal Processing. Note: If you are using CMSIS V 5.8.0, refer to the article below. How to integrate CMSIS-DSP libra...
Introduction Many customers requested to have FDCAN communicating at 8 Mb/s. We provide a GitHub hotspot that contains a simple project on several STM32 part numbers. The project allows for FDCAN to reach a bit rate of 8 Mb/s in the data phase. The ...
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...
