Introduction STM32 MCUs users may face an issue with CAN message reception mainly when the CAN2 instance is used. This issue may appear even if the hardware setup is correct, and CAN bit time and filters are configured correctly. If the value of Sta...
Summary To understand how middleware like NetXDuo and LwIP use the STM32 HAL Ethernet driver, this article demonstrates a bare metal application to send and receive Ethernet frames. SummaryPrerequisitesObjectivesStep-by-step instructions1. Board conf...
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...
How to configure and use the DTS (Digital Temperature Sensor) on the STM32H71. Introduction The DTS (Digital Temperature Sensor) was introduced in our high performance STM32H7 family. In this article we will see how to configure and use this peripher...
Introduction In this article, we discuss some debugging tips when the Ethernet is not working as expected. When working with the Ethernet peripheral on an STM32 either through a costume board and firmware or with one of ST provided boards and middle...
Introduction CAN bus is a robust protocol to transmit/receive data. It can be very sensitive to any issue that could lead to communication errors or even halt communication. STM32 users need to have a basic knowledge of the CAN bus (protocol + hardwa...
How to find the RAM ECC failing address? 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)? No...
Introduction For a firmware developer targeting and STM32 MCU based on a Cortex® M, they need to keep an eye on memory access, hardware availability, clock, and power to avoid running into issues that can be hard to follow and determine their root c...
Programming a STM32 with another STM32 Summary In this article, we implement the host side using one STM32 to program another STM32 via the USART interface by leveraging the native system bootloader. The entire project is available at our GitHub pag...
Summary This article provides a step-by-step guide on how to use the LwIP with the STM32H5 series. A simple DHCP connection is made using the NUCLEO-H563ZI board, outlining the process from configuring the basic hardware connections up to the firmwar...
Summary and problem description The STM32WL55 is a dual-core, low-power microcontroller with a sub-GHz radio that is connected internally through SPI. Note that whenever "radio" is mentioned in this article, it relates to "sub-GHz radio". To enhanc...
No. This is only possible if the communication bitrate does not exceed 1 Mb/s. A CAN2.0A/B transceiver cannot pass through bitrates > 1 Mb/s and transmitting higher bitrates could lead to communication errors due to distortions in bits. Find below...
Yes, it is possible. The transceiver does not have the intelligence to differentiate between CANFD and CAN2.0A/B and filter the CAN frame accordingly. It is just an active component that transforms digital signals to differential signals. The most i...
All STM32 have options and even though the functionalities may vary among the different families and series, they are all meant to allow the user a way to customize the general settings of the microcontroller. Option Bytes are mostly used to pre-conf...
1. Introduction Optimizing power consumption is one of the biggest challenges when designing an MCU based application.In this article we selected the STM32F401 MCU that can be configured in four different modes: Run mode, Sleep mode, Stop mode and St...
Introduction For those developing applications that use low power modes, trying to achieve the current consumption numbers listed in the datasheet and performing general debugging can be troublesome. The purpose of this article is to give an overall...
Summary The following article is a tutorial on how to implement the USB device, HID mouse class, using the Azure RTOS USBX package in standalone mode (without the RTOS). 1. Introduction Hello developer and welcome to this article! For this tutorial,...
Introduction Since CMSIS V 5.8.0, the CMSIS-DSP libraries are supplied as an individual package. The advantage is to decouple the release cycles of DSP from the CMSIS-Core stuff. As a side-effect, the DSP libraries structure was changed and the step...
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...
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...
