Ask questions and find answers on STM32 hardware set-ups, including schematic-related challenges, debugging probes, power configurations, and more.
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! 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...
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)
Hi,I am not able to connect NUCLEO-L4P5ZG board to a PC and ST_LINK utility. It alway gives me "unexpected error". Detailed message follows:15:06:46 : ST-LINK SN : 066BFF343039564157205441 15:06:46 : ST-LINK Firmware version : V2J35M26 15:06:46 : Con...
Hello,I just ordered a STM32769I-EVAL board, it has revision B.Reading via ST-Link says: Version: 0221Build: Aug 23 2019 16:24:56I did some tests and finally wanted to reinstall the original demo software.So I downloaded the demo binary from ST webs...
Why did they use such a strange new design for the ST-Link interface on this Nucleo board?The "older Nucleo/Discovery" ST-Link-Target connector (6 pin, e. g. CN11 on the Nucleo-LQFP64 boards) is missing.There is some "strange new mini size MIPI conne...
I have custom board with minimal design only stm32 chip is there and couple necessary capacitors and due to some soldering issue, i got shorted with 3.3 and gnd .. accidentaly i powered it on and for debuging it was connected like this for 2 minutes....
