Resolved! Hello. I am using in my project STM32F730V8T6 with external resonator (HSE) 16.000 MHZ (XRCHJ16M000F1QB1P0). When outputting the frequency to external ports, I will experience a spontaneous frequency change (16.1000-16.1080 kHz).
Before that I used STM32F030R8T6, there was no such problem. Tell me where I could be wrong?I am attaching screenshots of the organization of power supply and settings of the CubeMX
The unstable of sine wave generating signal by DAC
Hello, I have the problem of sine wave generation by DAC. Time to time when I generate the sine wave signal from MCU (STM32F302R8T6), the signal is unstable. I try to debug, and found that the issue might results from the hardware which is MCU. I wou...
Resolved! STM32L562ZET6Q CAD symbol wrong
I used stm32l562zet6q in my item，i found in product page zet6q cad symbol is same as zet6 but in datasheet is not.
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...
