Dear helpers,Thanks to valuable assistance from members of this forum I managed to get my project running on a STM Nucleo-H723ZG board, even with a USB-OTG connection to a VCP on my desktop PC. There is only one issue with this connection I c...
Hello, the reset pin of the stm32f103 chip I use uses this method to limit the current and pull it up, but there is a phenomenon that the chip cannot be programmed normally. After checking. The reset terminal potential is about 1.23V. The chip can be...
I want to display the image captured from the TW9990 camera sensor on the LCD screen using the STM32H7S78-DK kit. Since the data from the camera sensor is in YUV422 format, I am converting it to RGB565 format for the LCD. However, I am uncertain if m...
Dear STM Community,I am currently working on enabling USART6 for data transmission on my STM32F7508-DK board, but I have been unsuccessful so far. I have checked the datasheet for the correct RX and TX pin configurations, and I have tried two differe...
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...
