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
Hi, I'm trying to output sound on my touchGFX application on STM32H747I-DISCO. I used the BSP example from STM32Cube_FW_H7_v1.11 ( wich work fine) to implement the same process in a thread in my main code.So as a first step, i expect to loop the exam...
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...
I have an ADC+DMA read that can performs at 4Mbytes/second.The conv is 12 bit, clock division is 1_of5. On the callback DMS interruptsI send half data's to USB using CDC_Transmit_HS. The ADC buffer is 1K. I Also tried 2, 4, 8, 16k. I played with the ...
Hello,We are designing a board with an STM32H7B0VBT6 and USB3320 USB HS-transceiver. The MCU will run at VDD=1.8V. In AN5307, p. 11 it is written:"On some packages neither the VDD33USB pin, nor the VDD50USB pin are available, it is the VDD pin which ...
