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...
Introduction ST Open Bootloader is example application code for STM32 microcontrollers providing In-Application programming (IAP) and is offered in the STM32Cube MCU Packages and GitHub. It is fully compatible with the STM32 System Bootloader and sup...
Introduction Timing aspects are crucial in a CAN bus system design. The designer of the CAN bus system must study it carefully to prevent any communication issues on the CAN network.This article does not cover the CAN protocol description and its fra...
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...
Summary This article is intended for users who would like to integrate STM32CubeIDE and GitHub. It covers the entire process from GitHub account creation to integration with STM32CubeIDE. Introduction STM32CubeIDE is an integrated development envir...
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...
0. 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 sa...
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...
Introduction Clock configuration is a fundamental aspect of microcontroller (MCU) design, directly influencing the performance and power consumption of the system. In the STM32 series, the reset and clock control (RCC) peripheral manages the system...
