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...
Introduction As with many microcontrollers, STM32 MCUs could be clocked by an external source like crystals (XTAL) or crystal oscillators (XO). This is in addition to internal clocks such as LSI, HSI, MSI, CSI etc. For crystals, a preliminary calcula...
Do you need a fast slave interface with high throughput? This is for you.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...
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...
Summary The first stage bootloader (FSBL) is a key component in the boot process of STM32N6 microcontrollers. It’s responsible for initializing the system, configuring the hardware, and loading the application code from external memory into the inte...
Summary This article provides an overview of the low-power modes available in the STM32N6 series. It provides hands-on instructions for utilizing the Standby demo, detailing how RAM retention is implemented and how to run the demo code. Introduction...
Summary This article presents a tutorial for importing and using the legacy STMicroelectronics USB middleware in the new lines of STM32 to implement a CDC class to open a virtual COM port. The STM32H5 series was selected for this tutorial, but the st...
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 ...
