Will there be different typesetting for ST 32-bit MCU body screen printing of the same model? Will there be different screen printing layouts due to different origin, packaging and environmental materials.
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"
Resolved! ST-Link Utility - The elf loader file is not accessible
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...
STM32F051C8: High current draw from VBAT when VDD is on
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...
Resolved! Cant debug my own board with a STM32F303VB MCU - how to resolve this issue?
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...
Resolved! Blupill development board STM32cube IDE & STM32 utility problem?
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 ...
Detecting ST-Link V2-1 virtual COM port with C#?
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...
STM32L081KZT6 Programmging
Hello! I've developed a pcb using the STM32L081KZT6I power it with a 3v3 volt supply and I'm trying to program it via JTAG-SWDSo I connected the SWCLK and SWDIO pins to pin 24 and 23 as shown in the datasheet, then I connected ground and 3v3 to their...
Resolved! Would like information on the two pushbuttons on the Nucleo L476rg
Are there pins which enable external operation of the pushbuttons, the Black (Reset) and Blue (User) pushbuttons?Where is their operation described (and what are they named in that document so I can search for the details in the document)
