I am trying to source a 12.288MHz clock for an STM32L433 but having difficulties finding something.The clock is required for I2S playback with a bluetooth receiver (BT401).I have tried using the internal MSI RC to generate the 12.288MHz clock for SA...
One of the AF options on SPI1 is to use the SWD debug pins PB3-PB5.How can this be used in reality?Pretty obviously you can't do SWD breakpoints when SPI1 is thus mapped!But assuming no SWD debugging is needed, and you use SWD just to program the FLA...
Hi everyone, I'm using the NUCLEO-H7S3L8 to try to comunicate with a BOS1921 device using the I3C protocol. To get practice i'm trying to read form the Register Map in 6.10 (see the datasheet). Using some example codes from this link https://www.st....
Hello,I am working on a hobby project with https://www.st.com/en/microcontrollers-microprocessors/stm32f767zi.html.I have my own build and development environment based on arm-gcc-none-eabi and CMake and all HAL Drivers and Libraries from STM.The boa...
Problem When i call * USBPD_PE_SVDM_RequestAttentionI get a OK message response but the callback never gets called. * USBPD_VDM_SendAttention Curious to know if there's any good way to debug this? Current debugging stepsI have a STM32G0-Disco board...
Hi all,I am working on an STM32H755 project using external QSPI NOR Flash.I intend to use the QSPI Flash in two different ways:1. Memory-mapped mode for read-only resources (UI assets, fonts, images, etc.)2. Indirect mode for file system operations (...
Greetings!I have the following system:STM32U073CCVBAT pin is connected to a super-cap, and it's voltage was measured to be above the required minimum.During system reset (NRST) it behaves according to my expectations, the RCC_BDCR remains unchanged, ...
Hi guys i have a nucleo h7A3Zi-q dev board . i am trying to receive CAN messges sent from ESP32 borads . esp is sending can frame by using SN65HVD232D. and i configured the FDCAN to receive the can messages . esp can is set at 500 kbits , and my stm...
Hi, I am using the STM32H755ZIT6 dual-core microcontroller.The internal Flash memory has a sector size of 128 KB and a page size of 4 KB. In my application, I perform erase and write operations on a specific Flash sector. If a power failure occurs wh...
Hi There,So, I got some of the STM32C011J6 MCUs for my simple project of reading sensors data and generating an interrupt.But I am in a dilemma, that the MCU's has I2C Pins, SWD Pins for programming, GPIO pins to act as interrupt but how to initializ...
