My flash memory is getting erased in stm32 mcu after I power it off and on What could be the reason?I'm using stm32l562vet6 on a custom PCB. Once I upload the program untill the power is on the program executes properly even if I disconnect the st-li...
After creating my own STM32 PCB, which functions in the same manner as the WeAct BlackPill Development Board (utilizing the STM32F411CEU6), I found myself unable to connect to an external BLE board through UART. I utilized the same pins (Gnd, 3.3V, P...
could you please tell me - if I switch STM32F0Discovery from STLink to STM32F0 (using two jumpers) - will it show another usb PID and VID in my system?
Hi Community,I am currently facing an issue with my STM32H7B3I-DK board. The board was working fine, but suddenly, while I was uploading the code, the LD7 LED turned on indicating a low voltage fault. However, I am confident that the USB is providing...
Hello, I new with embedded hardware. I have a bluepill (original) and STLINK-V2 debugger (a not original).And now, I want to change the my STLINK-V2 for a new one, which I can make debug, not only programming.I found the STLINK-V3MINIE. But I'm sure ...
I am need to interface STM32F407 board with PDM digital mems microphone to Capture the Realtime sound waves through I2S Serial communication. But little bit confusion is there because in I2S communication there are three pin I2S2_ SD,I2S2_ CK,I2S2_ ...
