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...
This article extends the integration of the modular AWS FreeRTOS™ software by reconfiguring the original project to send an MQTT message to AWS and performing an action using the Rule Engine. This project runs on the STM32U585 IoT discovery kit and c...
