Hello People, I have 2 ST-Link/v2 here and I ordered another one from Mouser who arrived yesterday. So I decided to test it today. As a surprise, I plug it to my PC and opened the STM32CubeProgrammer. At first I saw the Serial Number in the ST-Link c...
Hi everyone, I just wondered if anyone is privy to information if STMicroelectronics is still in the maker business, that is do they plan any new Nucleo boards for hobbyists this year? Or maybe that was too much hassle for the company and not worth i...
I use STM32F030R8T6 and an interface card that plugs into a breadboard for direct prototyping, ST-Link v2 STM32 and STM8 Programmer, both from Newbiehack.com.Connected as on photo: SWDIO to pin 46 (PA13), SWCLK to pin 49 (PA14), GND to pin 62, 3.3V t...
Hello,I'd like to power my nucleo L152RE from a 3V external battery.I thought this should be easy but then I read that some soldering needed to be done? Is that true? I'd like to be able to power the board from an external 3V battery to use it as an ...
Hi, Everyone,I am developing the standalone SWD programmer operating by battery.I have a problem to program flash thru SWD directly.So, I traced SWD line with the ST-Link Utility. It looks that some tiny flash program code and updated user firmware a...
Hello,We've developed a custom board with STM32H750VB at the core. The relevant page of the schematic is attached. It is not communicating properly with the ST-Link on a STM32L053R8 Nucleo board. STMCube Programmer is the software used on Windows. Th...
Hello,I'm currently working on an PCB for an lecture about uC programming. It should be an education board for students to engage and learn hardware programming using an STM32 and the given ICs and interfaces on the board.Because this pcbs will be of...
Hi All!I am working on STM32H745 dual core controller and IAR Embedded Workbench for ARM toolchain V8.40.1 for development. I have completed all my work on individual core test and debugging with help of ST-Link V3 as debugger but unfortunately , I ...
For long term reliability and not dealing with interface subtleties I practice using 3.3V/5V translators (e.g. SN74LV1T34, ...) rather than taking advantage of the 5 volt tolerant inputs. I see this as reducing the voltage stresses & load current dr...
