We have a custom template project created in cubeMX for the board STM32H735-DK that was created only to have some functionalities,now I have taken that template and added the screen functionality and now im trying to add the touch functionality, I ha...
Hello,is there a possibility to turn on the OUT pin of the STLINK-V3PWR via openocd?I am currently using VSCode with opencd and gdb-multiarch for debugging. And I don't want to start STM32CubeMonitor-Power in the background all the time, to supply my...
I used NUCLEO-F103RB (MB1136 Rev C) and X-NUCLEO-NFC03A1 to run the example program in X-CUBE-NFC3. I received data from the serial port using 115200-8N1 and received the following: okcykkykkhht nkgkkkkfkca{sytcki{s{on qskkqcnsg Then I used a logic a...
Hi,I am working with the stm32h757 EVAL board, and I am trying to send some data to the PC using USART via STLINK VCP however I am not receiving anything on the PC side.In the board user manual and schematics, it says that USART1 is connected to the ...
Hi all,I am designing a PCB around the STM32H723 and wants to implement 4 bit SD card communication. As shown in the picture it can be done using 3.3V, with lower speeds, and avoiding these fine-pitch level translators. However does anybody have expe...
Hello,Target is power from another source. STlink from USB of laptopI was wondering if the power ON/OFF of STLINK and the target sequencing will damage either the devices? I had one STLINK v2 seems to be damaged while debugging and later it is not ab...
Hi team, I am doing experiment with NUCLEO-F439ZI board. after some time the LD4 "LED" was not glow. after I unplug the USB cable and reconnect the windows shows the flowing error"Power surge on the USB port – Unknown USB Device needs more power tha...
Hello Community,I want to use an external Debugger (Segger) with this Board. For this the jumper JP3 is left open to hold the STM32F7 (ST-LINK) in RESET.I attach the Segger to CN8. When connecting I get following message: Connecting to target via SW...
Hai all,I am using SDIO protocol for interfacing SD card with STM42F446RE.But While accessing the SD card, I am facing the following issues.1. Unable to access the card, even the card size , free space etc2. Also unable to open directory, and files. ...
I use STM32F4 Discovery, and when using I2C1 for communication, I encounter a situation where the chip becomes unresponsive while using UART and during operation with I2C1. When I use other I2C interfaces, it works normally. I want to understand what...
