STM32 MCUs Boards and hardware tools

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...

Resolved! We are currently doing a design with STM32H725REV. What should we do with the exposed pad in the middle of the package. Connect to ground or floating or?

Resolved! STM32F769BIT6 Operating current and temperature

HiWe have a board with STM32F769BIT6 MCU. When we drive the board with 3.3V, MCU current consumption is about 400~450 mA and it gets really hot!When we drive the board with voltages below 3V, for example 2.5V, it takes about 20~30 mA and stays cool a...

Resolved! I am miniaturizing the STM32F767ZI and need to know how to ensure it still has the USB ST-Link aspect, where can i find firmaware/resources for it.

I am miniaturizing the STM32F767ZI for a project I am working on and would like to have it function identically to the standard STM32F767ZI. Part of this includes having the ST-Link aspect of the board so we can program it via USB. I have not been ab...

Resolved! Problem with connecting STlink v2 and STM32L451CCU6

We buy original STlink v2 and we hawe problem with connect to STM32L451CCU6. On china programator MCU connect all time. On STlink connect time to time and if we are connented we can't program MCU. Bellow screen, first china programator, second STlink...
