I am using a custom PCB with stm32g474 and I am trying to get the CAN peripheral working. I believe I have everything set up correctly (bit rate, RAM etc) but when I call HAL_FDCAN_AddMessageToTxFifoQ(), FIFO is full error is raised after 3 iteration...
Hi!I'm trying to make a LCD screen work, but without success.I found this library:https://github.com/STMicroelectronics/stm32-ssd1315But I can'd find more documentation with examples (how to initialize).Can you give me a "wire"? Now I'm using a ssd13...
Hello,I am trying to enable the USB IP DMA mode on an STM32U5A5. Without DMA, I have it working as a USB device and it transmits and receives data without apparent issues. To start using DMA, my understanding is that all I need to do, in CubeMX, is c...
Dear All,I am testing the demo project for the NUCLEO-C071 to implement the USB HOST CDC_ACM (USBX). Below are some doubts that arose after the initial tests:After using the wizard to create the demo project 'Ux_Host-CDC_ACM', opening the .ioc file s...
Hi @stm32 I have a STM32G070 chip connected to a NOR_FLASH MX25L6433F using Standard SPI. I created an External Loader for the setup, but unable to read/write using the stm32 programmer. The custom driver for the particular flash is proved to work wi...
Hi ST Community,I'm working on an STM32H755ZIT6 project where I'm interfacing an SD card using SDMMC1 + DMA and FATFS (with exFAT) from the Cortex-M7 core. However, I'm facing a strange issue: the first time the board runs after programming, it write...
hello i have stm32f429i-disco card. fmc settings are configured. i defined sdram in the linker file but variable sdram is not written. can you help me? i am using cubeide. my linker file is attached and i am attaching the photo of my fmc settings. my...
Hi all,I am writing to you because I am trying to understand how to make the USB CDC ACM work on the Nucleo U5A5ZJ board. First of all I analyzed some ST webinars and tested the UX_Device_CDC_ACM program which works correctly. I tried to reproduce it...
I have NUCLEO-F756ZG board with STM32F765ZG and I have hooked up ICS43434 mic into I2S1 bus. Now I have been scratching my head for a day to figure out how to get data out from that puppy. Or actually getting data out is simple, but to make it sane i...
Hi guys, I'm trying to implement a sd card interface for the STM32U5 series using SDMMC1 interface. Since there is no native FATFS support over CubeMX, I guess, I started to use the generic fat file module from elm-chan.Basic configuration:1. SDMMC1 ...
