Hi We are trying to test USB Device - CDC standalone example with STM32H753i eval2 board. Our main.c code is enclosed herewith, Issue: if we call USBD_START() function in the main the LED Toggling code which is written below is not executing.In Debug...
I have been trying to get the debug setup running in CubeIDE 1.16 according to : dm00629855 Getting started with projects based on dual-core STM32H7 microcontrollers in STM32CubeIDE - Application noteAnd I was able do see the debug break point holdin...
Hello everyone. I am currently learning by working on a project in which I have to establish a SPI communication between a Nucleo U575ZI-Q and a STEVAL-MKI168V1 (IIS2DH eval board). To set up the Nucleo board and its peripherals, I used the STM32Cube...
I want to be absolutely sure, so should T_NRST be connected to CPU reset. (In this case STM32H750.)
Hi, While working on Nucleo Board for STM32L433RCTxx, I have configured 9 ADC channels for taking voltage inputs of 1.6 to 3.0V from individual cells of the battery. I am able to get the readings but they are not consistent, a few channels are missed...
Hi! Im looking for a microcontroller with a lot of gpio. I have looked into NUCLEO-H755ZI-Q. As I understand it shall provide me with 144 gpio but im not sure if I need some header for this to happen? I have read about ST Zio and morpho connectivity ...
Hello,I have an STLINK-V3MODS debugger, and I want to solder the 14-pin target JTAG socket. I see that there are messing components around when comparing the file "UM2502" page 13, Figure 7. MB1467 top layout to my real debugger. I see lots of missin...
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...
