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...
Stm32F407zgt6 (DevEbox)- how to use touch spi pins in tft connector
I have stm32f407zgt6 board. Came to work with Touch. On tft, I use Touch on xpt2046 via spi, on the stm32_f4x (DevEBox) board, the processor pins are wired as sck - pb0, miso-pb2, mosi- pf12. Pins data, CubeMX cannot map like any of the 3 spi on boar...
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...
