Resolved! My Nucleo-L152Re not connected by USART2 to PuTTY
Hello!I try to print message from my Nucleo-L152RE board by USART2 to PuTTY, but see only black screen without symbols. On other side, my Windows 10 see Virtual COM and I can to burn the code to Nucleo board from EWARM. What I must to do to solve ...
Compiling error.
Hi.Have you ever compile code with error: More than one section matches selector - cannot all be FIRST/LAST.I searching on google I see that the error because when appear two file same startup_stm32f746xx.s in Startup file and Divice File. I'm delete...
How to Trigger TIM2 via TIM3?
Hi. I'm reading Incremental Optic encoder with Timer3. The counter value is 4095 when the encoder rotates one turn. My goal is to produce pulses from 0-25ms through another timer when the Encoder turns half a turn. In order to do this, I am trying t...
STM32F051R8 not working after clock configuration
My device STM32F051R8 used to work without any issues prior to this. I was working with internal RC till then, and wanted to experiment with different clock source(HSE) and was trying out a code. It so happened that after flashing that code the devic...
Where can I find the STM32F469I Discovery Firmware zip file?
This file is mentioned quite a bit in the getting started notes but I can't seem to locate it on www.st.comThis is right out UM1962"Download the STM32F469I Discovery firmware from the www.st.com web page."
STM32F7 (Nucleo F767I) Ethernet Linkup Problem
Hello,I have generated sample project with latest STM32Cube for NUCLEO F767I and have ethernet linkup problems... (don't work)I have generated the same sample for NUCLEO F429ZI and working fine ! STM32F779I-EVAL (but here ist other MII PHY ) and work...
I2C clock not generated on SCK pin
I was working on i2c using STM32L476 nucleo board.I used stm32cube to make a code for keil.When I generated the code and programmed it in the board i found that the oscilloscope was not showing any clock on it .Oscilloscope's channel1 was connected t...
How to recover bricked STM32F051R8T6(STM32F0 discovery)?
My device is STM32F051R8T6, the same used in STM32F0 discovery board.I was tweaking with the clock configuration section to try different clock configurations like HSI and HSE, etc. I could erase, flash and verify the program successfully, however th...
USB Stall Behavior (CubeMx, CDC)
Hi,I'm struggling to integrate a USB interface into a bootloader. The microcontroller always stalls the USB communication. To find the cause of this problem I have set up a simple project to compare the USB transfers and came to a point where I can't...
