Introduction In this article, we cover the steps needed to use the Register callback's feature in STM32. The NUCLEO-H503RB (with an STM32H503RBT6 microcontroller) board is used, but the steps can be easily tailored to another MCU. All the implement...
Summary This article provides information about the STM32 boot process. In the first part, it gives you an overview of this process and it presents the different boot modes. In the second part, it details the STM32 system bootloader and the STM32 boo...
Summary This article aims to familiarize readers with STM32CubeMonitor by focusing on understanding its message structure and using the function node to create custom functionalities. The knowledge gained is applied in an example that implements a si...
Introduction There are many possible ways to access the System Bootloader in STM32 devices and, in this tutorial, we will cover how to easily perform this jump directly from application code for all our families and product series, except for the STM...
Introduction Many STM32 MCUs feature a CAN2.0 interface named bxCAN. The Loop back mode is one of the modes implemented in this peripheral. It is mainly used to test and debug transmit and receive CAN messages and mainly to validate the filter config...
Introduction This article addresses an issue where the USB_OTG_GRSTCTL_CSRST bit in the GRSTCTL register fails to reset, resulting in a timeout during USB initialization. The problem is related to timing and initialization, particularly with the USB ...
STM32 MCUs feature the system memory boot mode, which enables programming the device through the integrated peripheral interfaces, as outlined in AN2606 - Introduction to system memory boot mode on STM32 MCUs To select system memory boot mode at devi...
Introduction This article is a tutorial on how to get the STM32F769I-EVAL board’s CAN_Loopback example project working on the STM32F769I-DISCO board using CAN2. This example project was created for the STM32F769I-EVAL board. However, since the STM32F...
Introduction Understanding the absolute maximum ratings of STM32 microcontrollers (MCUs) is critical for ensuring their reliability and longevity. These ratings define the limits beyond which the device may suffer permanent damage. This article expl...
Summary This article is a step-by-step guide on how to use the push-pull mode with deadtime using the STM32G4 HRTIM (high-resolution timer). The example in this article is demonstrated using the NUCLEO-G474RE board but can be tailored to any other ST...
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 gives you the key information you need to dive into USB development on STM32. It mentions various resources, including training (MOOCs), articles, and application notes, that can help understand USB theory and hardware imple...
Welcome back with the part 2 of our article series that explains how to add a custom SPI flash memory in the External Loader portion of the STM32CubeProgrammer and in the STM32CubeIDE. In the first part we covered the pre-requisites and linker scrip...
Summary Recent STM32 series have an interesting feature called readout protection with password. It is possible to configure it using the SWD/JTAG debug interface or within user application code. The theory and an example of the first method is full...
How to access to the right RAMECC monitor to get the RAM failing address when an ECC error occurs?How to translate the content of the failing address register to the actual RAM address (e.g. FADD= 0x2004)? Note: For simplicity and clarity, the descr...
After programming my STM32H7/STM32H7RS 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/STM32H7RS’s SMPS or LDO firmware power configuratio...
Introduction The purpose of this article is to explain how to generate a custom signal, a sine wave in this case, using an STM32 Microcontroller’s DMA controller and a PWM output from a timer. Although this example uses the NUCLEO-H745ZI-Q, the same ...
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...
Is there an interface that replies to your need? Yes, it is the PSSI. What does a PSSI stand for? Parallel synchronous slave interface. What the PSSI interface is? A generic synchronous 8/16-bit parallel data input/output slave interface that...
Introduction Debug authentication is a critical security feature of the system considering that with a debugger the user can access a large part of the system. To control a reopening of the debug port, the device imposes a debug authentication proto...
