Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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 ...
Has anyone been able to convert a TouchGFX project from FreeRTOS to Azure RTOS by simply using the freeRTOS compatiblity module provided, then changing the oswrapper files to use non-CMSIS calls (pure FreeRTOS API) and no other changes? This would b...
Hello all. If I create a threadX build for say STM32L496QGI3Will I be able to use the same build in the entire STM32 line? Or just SMT32L's ?At what point do I need to build again?thanks
