figure-1 I2C waveform with STM32L433rc-p Nucleo board.When I try to use STM32L433RC-P Nucleo's I2C for communicating with AT24C01 I2C EEPROM, two strange waveform occurred. This strange waveform is not occurred from another model STM32 MCU.(example. ...
After testing trying to write a byte to Flash I seemed to have bricked board. I thought board just went out, so I bought another one, programmed it and now that board is broken too. I commented code out, tried 3rd board and it works fine.Here is th...
We have new boards with STM32L433RCT6 as MCU and only 30% of boards can program with STM32CubeProgrammer. Other boards just cannot connect to ST-LINK. I have tried these:1. Use "under reset" mode, not working2. Use JTAG signals. The good board can be...
Hi,I am trying to make both IKS4A1 and WB05KN1 (see datasheet attached) shields work together on a NUCLEO-U575ZI.Using the example projects I can use both separately. I used the SensorDemo_BLESensor-App from X-CUBE-WB05N (https://www.st.com/en/embedd...
Hello,is it possible to change the baud rate VCP to USART bridge of the STLINK-V3EC on the Nucleo STM32H7S evalboards?The documentation states the following:Virtual COM portThe serial interface UART3 (PD8/PD9) that supports the bootloader is directly...
I am working on the Nucleo C031C6 and struggling to use the virtual com port. The datasheet says that the virtual com port is connected to PA3 and PA2, so I want to send data to my computer with USART2. Unfortunately, I do not understand why the pins...
Using CN4, there are instructions for using an external debug probe to program the on-board STM32G474RE MCU. This seems strange given the fact that there's an embedded ST-LINK/V3, but I've made it work. What I would really like to do is use the emb...
Hello,we wanted to run some timing tests with USB on the NUCLEO-H7S3L8 together with the SVW (Serial Wire Viewer).CPUCLK is set to 600 MHz from the CDC_Standalone example, Trace and Debug is enabled.SWV always fails if the 600 MHz are set in the Debu...
We are designing a board for internal product development and testing (not for sale) based on NUCLEO-U575ZI-Q (the Altium source). We aim to manufacture a handful of boards for internal use during development. We will re-use parts of the existing des...
HiI have found that the STWINBX1 loses RTC at poweroff (or does CubeMX write code to reset RTC at poweron? there is a ticket on that) so that I have to battery-power it on, connect usb, update RTC and then disconnect while still on in order to log wi...
