Summary This article provides a quick guide on what the STM32N6’s OTP bits are and how to program them. It includes step-by-step instructions and explanation on configuring the OTP124, responsible for changing the VDDIOs' voltage to 1.8 V instead of...
Defining HSLV HSLV is a characteristic of certain I/O ports that allows them to operate at higher speeds while using lower voltage levels. This feature is particularly useful for applications that require fast data transfer rates without the higher ...
1. System (ROM) bootloader The system bootloader is present on all STM32 MCUs. As the name suggests, it is located on the system memory (ROM) area of the MCU. The system bootloader is located on the read only portion of the memory and is programmed ...
Summary This article is a step-by-step guide on how to use the half and interleaved modes of the STM32G4 HRTIM (high-resolution timer). The examples in this article are demonstrated using the B-G474E-DPOW1 board but can be tailored to any other STM32...
Introduction On the NUCLEO-WB55RG, we have an embedded ST-LINK/V2-1. However, for several reasons, users may want to use an external ST-LINK for debugging or programming. In this article, I demonstrate a simple use case of programming an STM32WB55RG...
Introduction Many customers requested to have FDCAN communicating at 8 Mb/s. We provide a GitHub hotspot that contains a simple project on several STM32 part numbers. The project allows for FDCAN to reach a bit rate of 8 Mb/s in the data phase. The ...
Summary This article shows how to implement inter-processor communication between CM7 and CM4 cores on the STM32H7 series through hardware resources. This article uses the bare metal OpenAMP method.If you're looking for inter-processor communication...
Introduction The USB Type-C® and USB PD specifications revolutionized device connectivity by merging data transfer and power delivery for up to 240 W (with EPR in USB PD 3.1). A key feature, fast role swap (FRS), allows a power supplying device quic...
Introduction Many STM32 users start their development based on one of ST boards either to evaluate the STM32 MCU or to get the proof of concept of their application. One of the first steps to do in the evaluation process is to look at the board schem...
Introduction The WB55CG USB dongle is included in the P-NUCLEO-WB55 bundle together with the NUCLEO-WB55RG. The WB55CG dongle does not have an ST-LINK/V2-1, but the NUCLEO-WB55RG does. The WB55CG USB dongle can be programmed through USB BootLoad or...
Introduction The NUCLEO-WB55RG has an on-board ST-LINK/V2-1 debugger/programmer. This ST-LINK/V2-1 is integrated on the same SoC as the MCU. This means that we cannot separate the hardware design into two parts; ST-LINK, and target MCU. For this rea...
