Hello,I have a doubdt and I haven't found the solution on the internet (probably I haven't asked properly or I have been missunderstood)The thing is that I have a peripheral driver,with a function to write and read to and from SPI, and between them, ...
USBD_CUSTOM_HID_SendReport(...) returns USBD_OK but nothing being send when code is generated with firmware version 1.12.1, but this function works without any problem in firmware 1.12.0
Hello, I wonder if it exists a basic example or application note illustrating how to configure the USB_OTG peripheral (host mode) of Stm32u5xx mcu as virtual port."Device USB" is anymore available under Middleware in STM32CubeMx and the USBx stack is...
Hi, I'm using STM32F429 to build a prototype. I found my board couldn't enter the USB bootloader mode. What I found was: Connect Boot0 to 3.3V via 100k ohm resistor, no pull down on Boot0. The MCU could enter USB bootloader mode properly. I can see a...
Hi, I'm trying to write i2c ISR by myself with LL. But after START condition address don't transfer(I see it in my oscilloscope), although I write to I2C1->DR address of slave and read reference manual with attention for proper handling.I generate in...
Hi,I prototype the use the USB virtual com port on a STM32F407 Discovery board andit worked without any problem. I then repeated the exercise on our custom board(STM32L4P5VGT6), the first stage was just transmitting it worked without aproblem. Now ad...
I am working with several STM32, let's focus on the STM32L4P5. I wrote a windows utility which does a nice job of loading code with the bootloader, per the AN3155 documentation. It is nicely robust, and I've been using it for a couple months. I wan...
Hello,I'm working on a NucleoF746ZG, for the past week i'm unable to communicate with board tought UART.The problem seems to be that HAL_UART_Init(&huartX) return 0 which means that the UART is not initialized.I tried to check if it was a hardware pr...
