I have recently created a PCB in which I am attempting to program external FLASH via the QSPI interface. It is a very simple 2-layer PCB. The MCU is the STM32H723ZGT6. I am using an LDO to convert the 5V USB to 3.3V. There is a power LED. There a...
Thanks to SofLit, I managed to create a new project from a configured .ioc file. The next objectif is to see if I can read CAN data from an instrument cluster I have on my bench.I am attempting to read the data from STMCubeProgrammer. I can connect t...
Here is a sequence of screen captures demonstrating the problem I'm encountering (in particular, the firmware version displayed by the software appears to become same as the firmware version intended for upgrade; the upgrade says it failed, but then ...
how to use PWM timer1 in Interrupt mode
Hello everyone, I'm asking for your advice. I use STM32F429I-DISCO1 board, I want to use I2S_3(PCM3) in SLAVE mode .The <WS> signal is located in PORTA 15 pin, at the same time the same pin is connected to U4 (STMPE811QTR) as <TP_INT1> signal (output...
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 ...
