Resolved! On STM32G431 is the BOOT0 pin (PB8) no pull-ups or weak pullup?
On the STM32G431x6/x8/xB UFQFPN48 I've been assuming that BOOT0 pin PB8 was a weak pull-up during reset, but in trying to track this I think it has no pull-ups/ pull-downs. Is this the case?
ST-LINK upgrade under Linux fails, do other options exist?
There were several issues so I am not certain which is the real issue.I am using STM32CubeIDE version 1.1.0Note I believe ST needs to consider more carefully how to install things and give direction when something seems wrong in installation. I belie...
Resolved! Is it ok to connect an ST-LINK V2 to a board which has a powered 3.3V rail?
I ask because I need to test the analogue part of a (custom) board which is powered from 12V, but also generates a 3.3V rail from that. I'd prefer to leave the ST-LINK connected if at all possible.
Resolved! How to connect VREF+ pin on stm32F722RET6?
I am designing a custom PCB using STM32F722RET6. How to connect the VREF+ pin(13) on the SMT32F722RET6?.As per the hardware development manual, it says"The VREF+ pin can be connected to the VDDA external power supply"and then, "VDDA=VDD and VSSA=VSS...
Resolved! In NUCLEO-L432KC Is it possible to use pins PB6 and PB7 if I have allocated pins PA9 and PA10 for the I2C1 port?
Hi ST community,I'm working with NUCLEO L432KC and in my application I need to use I2C1 port. Using STM32CubeMX to generate the project, I could see that when I enable the I2C1 port, Automatically the CubeMX allocate the PA9 and P10 pins. For my appl...
Miniature KNX transceiver - search for circuit faults
As part of a project work of my studies I have designed a board with which I want to read a KNX bus. Unfortunately, two identical prototypes broke down and I'm not sure why (the components were soldered cleanly and the PCB also made a very good impre...
Resolved! Don't drive LEDs from these pins. "PC13, PC14 and PC15 are supplied through the power switch". What does this power switch really do?
SummaryAt the end of the day, my issue is missing something in documentation. The lesson here, is test thoroughly. Just because it works for a few minutes, doesn't mean forever. Anyway, I've been running >3mA through the pins that are limited before ...
Resolved! STM32L011F3U6TR mcu boot0/PB9 pin has internal pull-up/pull-down resistor feature?
Please help to find out whether STM32L011F3U6TR mcu boot0/PB9 pin has internal pull-up/pull-down resistor feature. There is no mention that boot0 pin is special in this respect, ie no internal pull-up/pull-down resistor. On my board, unable to bring...
STlink V3 connections.
I want to be sure of the interconnects between the STlink and STM32 that will give me full debug capability using the CUBEIDE development environment. It would require 4 connections; 3.3v,gnd, SCLK(PA13) and SDIO(PA14). Some STM docs identify two add...
