dear sir we are using ST microcontrollers in our machines. we need to know how we can read the program logic written in memory. however we are using STM32- utility link for debugging the error but in that software we can't explore the program logic.
for your information we are using .srec software file. we want to open this file in readable format.
Why in the STM32H7445I-DISCO Highspeed path length we only consider the length between the resistance and the ram, but not the length of the resistance to the MCU (for example the netRXX to the MCU pin)? So we don't consider the full path between MCU-RAM?
I am a student starting in highspeed tuning...
Resolved! External SMPS VDD12 pin supply required?
Hi, I have to use STM32L562CEU6P on my project.This uP has two VDD12 pin for external SMPS.My question is simple, this SMPS supply is required or can I left this pins floating?I don't need this feature and manual is not very clear.Thanks in advance.
Resolved! What is the pin for the user LED on UM2516?
Hello,I am using an UM2516 (B-G431B-ESC1 Discovery kit) eval board with the STM32G431 microcontroller.In the documentation is written:"2 user LEDs: 1 green LED for 3.3 V level, and 1 red LED configurable by the user"I want to use the red LED as visua...
Resolved! LSE won't start - Do I have to big capacitors?
Hi!I'm using FC-12M 32.7680KA-A5 LSE crystal and my STM32F373VBT6 won't start if I'm suing LSE crystal. But if I'm suing LSI crystal, then my STM32 will start.I have made two(2) boards and both of them LSE won't start. My suggestions why are:To big ...
Discovery board stm32f746 with i cannot connect anymore on the st-link port
Hi, I have a discovery board stm32f746 with witch i cannot connect anymore on the st-link port.. Windows does not detect anymore the st-link port .. i took out the chip put it on a smal test board and the chip it's ok is detected as st-link... but on...
Resolved! Re-Generating with CubeMX sets the project to ST-LinkV2 instead of ST-LinkV3. It will not recover until I delete the generated folders. Initially CubeMX generates correctly.
I am working with IAR EWARM 9.10.1 and STM32CubeMX 6.2.1 on a NUCLEO-H743ZI2.To reproduce:Create NUCLEO-H743ZI2 project in STM32CubeMXGenerate itStart IARDownload to target (compile & flash succeed)Change something in IAR, e.g. add a source file to p...
Resolved! Is it mandatory to power STM32G473 from 3.3v only when I need in USB functionality?
I am going to use STM32G473 for my application. Most of peripheral interfaces need in 1.8v power (QSPI, I2C, GPIO, etc.) but i need in USB device functionality too.There is a requirement form data shhet (DS12712 Rev3 p174) to power USB tranciever fro...
Hi all, i am using a STM32 Nucleo-144 developement board with the STM32F429ZI MCU and i am powering it with a 5V Battery. In the Datasheet it says that Pin7 is a 3.3V output. Can i use this Pin to power a Sensor?
I am referring to this datasheet (page 52) : https://www.st.com/resource/en/user...ucleo144-boards-mb1137-stmicroelectronics.pdf
