Introduction STM32F3 microcontrollers offer three levels of read-out protection: level 0 (no protection), level 1 (Flash memory, backup SRAM, and backup registers protected), and level 2 (same as level 1, but with permanent protection by locking the ...
Introduction STM32F2 microcontrollers offer three levels of read-out protection: level 0 (no protection), level 1 (Flash memory, backup SRAM, and backup registers protected), and level 2 (same as level 1, but with permanent protection by locking the ...
Introduction Most of STM32Fx microcontrollers offer three levels of read-out protection: level 0 (no protection), level 1 (Flash memory, backup SRAM, and backup registers protected), and level 2 (same as level 1, but with permanent protection by lock...
Summary This article provides the necessary information for getting started with the B-U585I-IOT02A IoT Node with Azure IoT 1. Hardware The B-U585I-IOT02A discovery kit provides a complete demonstration and development platform for the STM32U585AI mi...
1. Programming without JTAG/SWD probes There are a few reasons a bootloader is needed in a microcontroller, including the main one: programming/updating the user application without the need of JTAG/SWD probes with the desired level of security neede...
Yes, any Flash page can be cycled more than 10 000 times.Each Flash memory cell can be programmed and erased up to 100 000 times. However, the total cycling capability for one complete bank is limited by the programming/erasing circuitry (such as the...
1. Introduction DMAMUX is included in the latest STM32 microcontrollers (STM32H7/G0/G4/L4+/L5/WB/MP1 Series) and is an enhancement over the previous DMA controller, providing more flexibility and fully dynamic peripheral request mapping over pseudo-d...
Following Part 1 Step 3: Building Binary file for Bank1 1. Add FLASH_BANK1 as preprocessor: Project Options> C/C++ Compiler > Preprocessor 2. Check that vector table settings are as following (Project Options > Linker > Linker Configuration File Ed...
1. What is STM32CubeProgrammer? STM32CubeProgrammer is our standalone software tool that can automate STM32 programming via a very easy graphical or command line interface. The tool can also be used to read and configure Option bytes. This tool suppo...
1. Introduction One of the many features that STM32CubeMX embeds is the cross-tool selector which we’ll be focusing on in this article and discussing one of its use cases.The cross-selector tool is a tool embedded in the STM32CubeMX that allows users...
How to use STM32CubeProgrammer and the STLINK-V3SET to access the SPI bootloader on my STM32 board? Our example here, we will use the Nucleo-G071RB as our STM32 reference board along with the STLINK-V3SET to show you how to leverage the STM32CubeProg...
Introduction One of the many features included in STM32CubeMX is the ability to allow users to select and configure the MCU’s or MPU’s clocks through a GUI (graphical user interface). In the clock configuration tab, users can: select from various clo...
1. Introduction This article shows how to implement and redirect the scanf function to the UART, in a nonblocking way. Therefore, was chosen that this function is working through tasks on FreeRTOS™ and so the main code is located at the FreeRTOS™ app...
This is an application note and contains a list of examples about 2 distinct topics: Receiving data with UART and DMA when application does not know in advance size of bytes to be receivedTransmitting data with UART and DMA to avoid CPU stalling an...
In this article, you learn how to visualize real-time use data that your IoT hub receives with a Node.js web app running on your local computer. 1. Introduction In this article, we use an IoT Hub, which has the B-U5U5I-IOT20A board connected to it. B...
