That is the ST-link V3 on NUCLEO-H755ZI board.The HSE MCO option is set to HSE/3, how to change it to HSE/5.Usually this is configurable in code, but this is ST-link firmware. If there is a way to change the division value, please some one let me kno...
Hi,I'm powering my NUCLEO-G031K8 from external 5V (LD2 led is On as expected) but the MCU stays in reset state (Vnrst=1.32V). I've changed the NRST_MODE to 1 (Reset Input only) with no success. The embedded ST-LINK is driving the MCU reset but in thi...
Hello dear community,I've started using STM32H743VGT6 on a custom board I've made.I'm testing the hardware now and I quickly detected that the temperature is really high (approx. 70°c on the top of the chip package).I have another board, based on a S...
I recently learned about Timers and I looked through the RM and DS of the MCU and I am trying to set up my TIM6 but it seems that I cannot even enable any Timer peripheral clocks in the RCC_APB1ENR register at all, I can write to bits 31-11 but bits ...
Hi Everyone!I am pretty new to the community and STM32. I have been trying to set up the Nucleo F429ZI board to act like a an HID keyboard and send keystrokes. I have initialized the USB_OTG_FS to Device Only, USB_DEVICE to HID, and as far as I can...
I create project with CubeMX, use Keil MDK IDE, CM7 core without user code , CM4 core has simple user code. Download code to both CM7 and CM4 then code runs correctly. Then switch to debug mode for CM4. Now, if i press Reset button on board or press ...
I just bought a NUCLEO-H7S3L8H kit. I have successfully tested a few demo programs, for example "\STM32Cube_FW_H7RS_V1.1.0\Projects\NUCLEO-H7S3L8\Examples_LL\USART\USART_Com_Rx_IT_Continuous_VCP_Init\MDK-AEx". Then I create a simple project with STM3...
I can get the right WHO_I_AM(0x70) from mpu6500 by i2c,but I cant read other register or write other register.I cant read the gyroscope/accelerometer . whats more ,i changed some mpu6500,and it doesnt work.
This fault has appeared very abruptly. One hour ago I was working with the board just fine, programming via STM32CubeIDE. Then I swapped the board to a different USB port on my laptop, now it is not programmable.When I hit the 'Run' button, it appea...
I am working with a Nucleo-H745ZI-Q development board and want to put it to standby mode to measure current consumption. I have put the domain D1, D3 in M7 and then domain D2 in M4 in standby mode. I also use 1 user LED for each core, so that I can k...
