Hi, I have a Nucleo 144 STM32H743ZI2 and I try to convert 3.3v to 5v with level converter to send signal to a driver. I bought a Level Converter MH but when I measure the high voltage, marks 2.5V and in the low voltage 3.2v. I tried putting 3.3v from...
The typesetting of the second picture is inconsistent with that of the datesheet, does it exist? In addition, what is the meaning of E3 and E4, and what is the meaning of "X"
Hi,I'm trying to program a 32-bit STM32 Cortex-m4 MCU (specifically STM32L4P5ZGT6P).I'm using v 4.6.0 of ST-Link Utility, and I've tried both an ST-Link V2, and an ST-link V3, both with latest firmware.Both succeed at connecting (reading) the MCU, bu...
I have a minimal prototype circuit (breadboard actually) with this schematic: The firmware initializes a few peripherals (including the RTC) and enters an infinite loop calling __WFI(). Nothing else happens and nothing else outside the BOOT0 pulldown...
Hi,I just powered up my own board and i just wanted to start debuging.The first thing i tried was to connect with the STM32 ST-Link Utility and an ST-Link V2.This works fine. I can connect via SWD and can read the Chip-ID and see the Flash.In terms o...
Hi , Recently i buy STM32F103c8 Bluepill development board. I use STM32CUBEIDE create LED project and download using STM32utility tool. After programming done it will be automatically disconnect.Next, If need connect in STM32utility means need reset ...
Hello,I want to connect to the VCP of a Nucleoboard by a C# application. I don't want to iterate through all available COM ports on the system, so I'm searching a way to detect if one or more Nucleoboards are connected and connect to the correspondin...
Hello nice people. I am supposed to develop a board that will have 2 STM MCUs (STM32F334 and STM32F01).Is it anyways possible to be able to program both MCUs (simultaneously or individually) using a single SWD port. I know how to do it using JTAG cha...
