This article provides guidelines on how to use the LPBAM feature in the STM32U5 series to allow peripherals to be autonomous and optimize the power consumption in STOP2 mode.The LPBAM stands for low-power background autonomous mode. It is an operatin...
How to build a GUI application for the STM32F469-Discovery board using the STemWin Graphical library and starting from the CubeMX tool default configuration ?When selecting an ST development board such as the STM32F469-Discovery one some default sett...
STM32CubeMX is a graphical tool that allows users to configure STM32 MCUs (microcontrollers) and MPUs (microprocessors) quickly and simply. In addition, the tool also assists in generating the corresponding initialization C code for the Arm Cortex-M...
Every STM32 comes with a STM32Cube MCU package composed of the STM32Cube hardware abstraction layer (HAL) and the low-layer (LL) APIs, plus a consistent set of middleware components (RTOS, USB, FAT file system, etc). In addition, all embedded softwa...
STM32s are typically composed of a mixture of three-volt (3V) tolerant and five-volt (5V) tolerant GPIOs. Tolerant represents the voltage value which can be accepted by the GPIO. Please be wary of each GPIO's maximum voltage tolerance, as applying mo...
Summary This article allows the process to regress from RDP 2 to RDP 0 on the STM32U5 series. This example uses the STM32U5 Nucleo board with STM32U5A5ZJT6Q and STM32CubeProgrammer V2.13.Note:To regress from RDP2 to RDP0, you must be sure that your ...
This is part 1 of an article. To read part 2 click here. Summary For this demonstration, we configure a Nucleo-U575 using STM32CubeMX and generate the source code to display a low power application. We utilize the two LEDs and a push button that are...
Summary In a secure application, it is common that one would need to take simultaneous advantage of both flash memory read protections (RDP) and the TrustZone® controller. In this configuration however, there is a possibility of putting the device i...
How to configure the MPU of an STM32 using STM32CubeMX1. Introduction The MPU (Memory Protection Unit) is included in the Cortex-M4 and M7 based STM32 Microcontrollers (refer to specific product datasheets to confirm availability). The MPU can be use...
How to load and view the professional looking TouchGFX graphical demo on a low cost STM32G0 based solutionIntroduction TouchGFX framework includes support for low-cost microcontroller based applications, such as the STM32G0, with a professional looki...
Summary This article describes the steps that are needed in Keil®'s µvision configuration to ensure proper time measurement value is given when using the event recorder. STM32CubeMX Setup In this example, we use the STM32L746 Nucleo board. The dir...
Summary This article describes the steps that are needed to make time measurements of code execution using the GPIO pins 'EVENT OUT' function and a lab oscilloscope. Most of the STM32s GPIOs can be placed in an alternate function of EVENTOUT. In th...
Introduction In this article, we cover the needed steps to use the FreeRTOS™ in tickless mode, specifically entering in STOP2 low-power mode with the STM32U5. In this example, we use the X-CUBE-FREERTOS™ pack with the LPUART and EXTI as the wake up s...
How to set up the LTDC peripheral to interface with the display panel ATM0500D27-CT from AZ Displays1. Introduction The STM32’s integrated LTDC (LCD-TFT Display Controller) peripheral can be used to interface with parallel displays. It is very common...
How to configure and use the STM32’s ADC Analog Watchdog feature1. Introduction In most of the STM32’s ADC (Analog Digital Converter), there is a feature called the Analog Watchdog. In this article we will learn how to configure it using the STM32Cub...
In continuation of part 1 of this article [1], we will also briefly discuss how you can easily export your STM32 project to different STM32 series using the “List pinout compatible MCUs” option in the STM32CubeMX. 1 Troubleshooting sourcing the STM32...
